Sustainable Software Engineering is an emerging discipline at the intersection of climate science, software, hardware, electricity markets, and data center design. In the most recent InfoQ Trends Report on architecture, the InfoQ team added designing for sustainability for the first time, suggesting that it's emerging because people are realizing that the software industry is responsible for a level of carbon usage comparable to that of the aviation industry. The question then is what can we do as individual developers and architects, if anything, and what role does the broader shift to the Cloud have? Charles Humble explores the topic with Microsoft's Asim Hussain, green cloud advocacy lead and chair of the Green Software Foundation. They discuss techniques such as demand shifting, as well as the current challenges that the Green Software Foundation is aiming to address.

This episode is a panel discussion from the microservices track QCon Plus, held in May 2021. Track host Nicki Watt asks "What have we learned over the last decade of microservices." The panelists included Chris Richardson, James Lewis, and Katie Gamanji. The discussion started with looking at how the meaning of "microservices architecture" has evolved over the past ten years. There were some great insights about how successfully developing, deploying, and maintaining software depends as much or more on cultural and environmental factors, than simply adopting microservices and all the tools and technology that now exist.

In this episode of the InfoQ podcast Charles Humble talks to Michael Perry about his book “The Art of Immutable Architecture”. They discuss topics including the eight fallacies of distributed computing: a set of assertions made by L Peter Deutsch and others at Sun Microsystems describing false assumptions that programmers new to distributed applications invariably make. Other topics include Pat Helland’s paper “Immutability Changes Everything”, Eric Brewer's CAP Theorem, eventual consistency, location independent identity, and CRDTs. They also discuss how the approach to building distributed systems advocated by Perry could be introduced to a real-world enterprise app that needs to integrate with mutable downstream systems.

Observability is a crucial aspect of operating Microservices at scale today. Today on the InfoQ podcast, Wes Reisz speaks with Chronosphere’s CEO Martin Mao about how he thinks about observability. Specifically, the two discuss Chronosphere’s strategy for implementing a successful observability program. Starting with alerting, Martin discusses how metrics (usually things like RED metrics or Google’s Four Golden Signals) are tools to aggregate counts and let operators know when things are moving towards an incident. In stage two of this approach, operators begin to isolate and triage what’s happening in an effort to provide a quick system restoration. Finally, Martin talks about root cause analysis (RCA) in the final stage as a way of preventing what happened from happening again. Martin uses this three stage approach (and the questions that should be asked in each of these stages) as a way of focusing on what’s important (or reducing things like Mean Time to Recovery) in a modern clo

In this episode of the InfoQ Podcast, Thomas Betts speaks with Chris Richardson about minimizing design-time coupling in a microservice architecture. Chris begins by defining design-time coupling, and contrasts it with runtime coupling. We then discuss some of the problems that arise from design-time coupling, anti-patterns and symptoms that are warning signs of high coupling, and the trade-offs that architects need to consider in their designs.

In this podcast, John DesJardin, Chief Technology Officer at Hazelcast, met with InfoQ podcast co-host Thomas Betts to discuss the idea of continuous intelligence. This is a paradigm shift from traditional business intelligence, and relies on a corresponding move from batch-based ETL and reporting to continuous processing of streaming data. Although the languages being used, such as Python and SQL, will be familiar, developers must pay special attention to the characteristics of time-series data, especially in near-real-time scenarios. We cover the current state of the tools and technologies in use, why companies are adopting continuous intelligence to remain competitive, and we even get a bit into what the future of data processing and analysis will look like.

The container runtime is software that executes containers and manages container images. Today, when many people think about a container runtime, they're likely thinking of Docker. However, Docker is more a set of tools for building, packaging, sharing, and running a container via Docker Daemon that then makes syscalls to another tool like containerd. Containerd, in turn, makes calls to an implementation like runc that lays down the file system for the container and is the executor for the process. Today, on The InfoQ Podcast Wes Reisz talks with Phil Estes, one of the containerd maintainers, about container runtimes. The two discuss the significance (in detail) of the announcement that dockerhsim will soon be deprecated in Kubernetes, the complete container runtime stack, work the Open Container Initiative (OCI) is doing today on a third container spec around registries, and more.

The Open Policy Agent is used for policy decision-making across the stack. In the case of Kubernetes, it is often used as an admission controller to protect the API Server with dynamic rules that don’t require recompilation to introduce. Today on the InfoQ Podcast, Wes Reisz speaks with Tim Hinrichs and Torin Sandall (two of the Open Policy Agent Project creators). The three talk about the project, including things like architecture, origin, community, the policy language (Rego), and, of course, performance. The podcast is an introduction to how OPA can is used across the stack for policy decisioning.

Several years ago, today's guest Michael Feathers published a book called Working Effectively with Legacy Code. This book introduced ways of wrangling large codebases. In the book, Feather's discussed leveraging unit tests to introduce--not only a validation of correctness but also-- documentation on a system's operation, ways to decouple/modularize monolithic code, and 24 different techniques to introduce change safely. Today on the podcast, Wes Reisz and Michael Feathers go back and review the book. The two spend some time reviewing key concepts from the book and then discuss how the techniques can be applied today. The two wrap with a discussion on what might change in a new version of the book.

In this podcast, Shannon Williams, co-founder and president at Rancher Labs and Darren Shepherd, co-founder and CTO at Rancher Labs sat down with InfoQ podcast co-host Daniel Bryant. Topics discussed included: the adoption of hybrid cloud across organisations, the evolution of Kubernetes as a key abstraction for portability and cross-cloud security, running thousands of Kubernetes clusters at the edge, and the value of open standards. Why listen to this podcast - Organisations are adopting hybrid cloud strategies. The use of containers to package and run applications across clouds has seen large adoption over the past five years. Containers and Kubernetes are everywhere: the datacenter, the edge, embedded systems, and other locations. - Two enterprise use cases for Kubernetes stand out: providing standardised abstractions and APIs to increase portability across vendors and cloud platforms; and providing a framework and homogenised foundation on which to build and implement (cross c

In this podcast, Nora Jones, Co-Founder and CEO at Jeli and co-author of O’Reilly’s “Chaos Engineering: System Resiliency in Practice”, sat down with InfoQ podcast co-host Daniel Bryant. Topics discussed included: chaos engineering and resilience engineering, planning and running effective chaos experiments, and learning from incidents. Why listen to this podcast: - The chaos engineering and resilience engineering fields, although inextricably linked, are often incorrectly conflated. Resilience engineering is focused on “identifying and then enhancing the positive capabilities of people in organizations that allow them to adapt effectively and safely under varying circumstances.” - The UX of internal or engineering-focused tooling, such as chaos experimentation tooling, is extremely important. However, engineers that create these tools often overlook the value of UX, or don’t have the relevant skills in user design research to undertake this. - We all work in socio-technical syste

In this podcast, Rob Skillington, co-founder and CTO at Chronosphere, sat down with InfoQ podcast co-host Daniel Bryant. Topics discussed included: metrics collection at scale, multi-dimensional metrics and high-cardinality, developer experience with platform tooling, and open standards related to observability. Why listen to this podcast: - Over the past ten years the requirements related to monitoring and alerting, and the approach taken to implement this, has changed considerably. Compute is now ephemeral and dynamic, services are more numerous, and engineers want to instrument more things. Scalability of a monitoring solution is vitally important. - One of the challenges with metric data is the limited information for providing context for collected values. This can be solved by using multi-dimensional metrics. Dimensions of a metric are name-value pairs that carry additional data to describe the metric value. High dimensionality can lead to high cardinality. - Uber’s M3 metri

In this podcast, Johnny Boursiquot, Site Reliability Engineer at Heroku, sat down with InfoQ podcast co-host Daniel Bryant and discussed topics that included: why Go is a useful language for building Function-as-a-Service (FaaS) style applications; how Heroku implement the role of Site Reliability Engineer (SRE); and why the ability to teach is such a valuable skill. Why listen to this podcast: - Go is a useful language for building Function-as-a-Service (FaaS) style applications. The ability to build Go applications into a static binary reduces the need for dependency management, and the quick runtime and application start time is good for initiation and scaling - The FaaS development toolchain has improved over the years. Many cloud providers now provide local runtimes, e.g. AWS SAM Local, and service simulators, e.g. LocalStack. Testing in production is facilitated by the ability to do dark launches and canary releasing at the ingress/API gateway - Developing “serverless” appli

In this podcast, Matt Debergalis, Founder and CTO at Apollo, sat down with InfoQ podcast co-host Daniel Bryant. Topics discussed included: the motivations for GraphQL, the Apollo Data Graph platform, data modelling in an enterprise context, and how incrementally adopting GraphQL can help with decoupling the evolution of frontend and backend systems. Why listen to this podcast: - The challenges of defining client-side-friendly data models, building maintainable and composable backend APIs, and moving data from the cloud to a client application contributes to making modern software development difficult and time consuming. - GraphQL is an open-source data query and manipulation language for APIs, and a runtime for fulfilling queries with existing data. GraphQL lets application developers describe the data they need and bring that data into the screens that they are building for their users. - The Apollo Data Graph platform is a middleware layer that provides a way of decoupling th

In this podcast, Lin Sun, senior technical staff member and master inventor at IBM, and Neeraj Poddar, engineering lead and architect at Aspen Mesh, sat down with InfoQ co-host Daniel Bryant. Topics discussed included: the evolution of service mesh data planes and control planes, the new Istio 1.5 architectures, Istio WebAssembly extension support, and the future of service mesh technology. Why listen to this podcast: - A service mesh in one implementation approach to provide service discovery, traffic management, and cross-cutting communication concerns that engineers see when they adopt (micro)service-based. - The data plane of most modern service mesh implementations run out-of-process as a proxy sidecar. This has evolved from library based implementations, such as Airbnb’s SmartStack or Netflix’s OSS libraries. - The recent release of Istio 1.5 saw the deployment packaging of the control plane move from a microservice-based approach to that of a monolithic implementation, nam

Today on the InfoQ Podcast, Wes Reisz talks with one of the thought leaders in Microservices, CI/CD, and Cloud -- Sam Newman. The podcast covers many of the topics, techniques, and patterns that Sam writes about in his latest book, Monolith to Microservices: Evolutionary Patterns to Transform Your Monolith. Topics covered in the podcast include understanding the problem you’re trying to solve, organizational/people changes when it comes to microservice architectures, database strategies for decomposing monolithic datastores, and why we’re seeing projects reverting from microservices to monoliths. Why listen to this podcast: - Fundamentally, microservices are distributed systems. Distributed systems have baggage (complexity) that comes along with them. The best way to deal with this complexity is not to address it. Try to solve the problem in other ways before choosing to take an organization to microservices. - A common issue that large enterprises run into that might be a strong

In this podcast, Tracy Miranda sat down with InfoQ podcast co-host Daniel Bryant. Miranda, Director of Open Source Community at CloudBees, and board chair at the Continuous Delivery Foundation (CDF), discussed topics that included: the aims of the CDF and an outline of the current hosted projects, the need for open standards and interoperability in the CD space, and the benefits offered by progressive delivery and software supply chain management. Why listen to this podcast: - The Continuous Delivery Foundation (CDF) serves as the vendor-neutral home of many projects within continuous delivery space, including: Jenkins, Jenkins X, Spinnaker, Tekton, and Screwdriver.cd - Jenkins X is a Kubernetes-native continuous delivery solution for cloud applications. This project uses a completely new architecture and code base in comparison with the original Jenkins project. - Spinnaker is an open source, multi-cloud continuous delivery platform. The Tekton Pipelines project provides Kuber

In this podcast, Marty Abbott and Tanya Cordrey sat down with InfoQ podcast co-host Daniel Bryant. Abbott, CEO and co-founder of AKF Partners, and Cordrey, partner at AKF Partners, discussed topics that included: their learning from working together in the early days of eBay, why and how to avoid creating software systems that are composed of deep call chains of microservices, and how to build effective product teams. Why listen to this podcast: - First introduced in the book “The Art of Scalability”, the AKF Scale Cube is a model for segmenting software components, defining microservices, and scaling products. It also creates a common language for teams to discuss scale related options in designing solutions. - The microservice architectural pattern is best used for implementing the “breadth” of business functionality. Engineers should avoid building deep call chains of services, as this can increase the probability of failure, and can also increase the challenges of locating and

In this podcast, Daniel Bryant sat down with Dave Sudia, senior DevOps engineer at GoSpotCheck. Topics discussed included: the benefits of PaaS; building a platform with Kubernetes as the foundation; selecting open source components and open standards in order to facilitate the evolution of a platform; and why care should be taken to prioritize the developer experience and create self-service operation of the platform. Why listen to this podcast: - When starting a business and searching for product-market fit, creating an application using a monolithic code base deployed onto a commercial Platform as a Service (PaaS) product is a very effective way of iterating fast and minimising operational costs. - There may come a point where the PaaS cannot provide bespoke requirements, or it has trouble scaling, or the costs become prohibitive. At this point many teams choose to build a custom platform using cloud technologies, such as Kubernetes. - Building a Kubernetes platform can be an

Today on The InfoQ Podcast, Wes Reisz talks with Peter Bourgon. Peter is a distributed system engineer working on Fastly. His area of interest is around coordination free replicated systems. The two engineers talk about the space of Conflict-Free Replicated Data Types (CRDTs) specifically in the context of edge compute. Topics covered on the podcast include Edge compute, CRDTs, CAP Theorem, and challenges around building distributed systems. Why listen to this podcast: - CRDTs (conflict-free replicated data types) are a class of coordination free replication systems (or systems that don’t require strategies such as leader election). - An easy way to think of a CRDT is as an associative, commutative, and idempotent data structure plus the operations needed to use it. The edge is an overloaded term that people tend to define based on where they sit on a spectrum between the customer and the data center. Fastly’s edge is away from the data center and but not to the telephone pole or

In this podcast, Daniel Bryant sat down with Joe Duffy, founder and CEO at Pulumi, and discussed several infrastructure-themed topics: the evolution of infrastructure as code (IaC), the way in which the open source Pulumi framework allows engineers to write IaC using general purpose programming languages such as JavaScript and Go, and the future of multi-cloud environments. Why listen to this podcast: ● Infrastructure as Code (IaC) enables engineers to programmatically define the configuration and provisioning of computing infrastructure, on-premises hardware, and cloud services. ● Traditional IaC tools were often imperative, requiring engineers to define and enumerate the necessary steps and SDK calls in order to configure the underlying infrastructure. ● Modern IaC tools like HashiCorp’s Terraform, AWS CloudFormation and other related cloud vendor tooling enable engineers to write declarative code to define a required state of the infrastructure. The tools parse the declarative co

In this podcast Charles Humble spoke to Dylan Schiemann, co-creator of Dojo and InfoQ’s JavaScript and Web Development lead editor, about the history and current state of Dojo, and key emerging trends in the JavaScript landscape today. Key topics include Dojo’s adoption of Typescript, web components, and client-side libraries such as Svelte and Stencil. Why listen to this podcast: - Modern Dojo (2.0 and upwards) is focussed on being a very small, opinionated reactive framework, but with a lot of the components you need to build a modern JavaScript application built in. - The framework tries to align closely to standards, for example using Web Components extensively for UI components, alongside ES modules and promises. The use of standards, as well as the convergence towards the reactive programming model for web UI, has improved interoperability, though there are some limitations such as the lack of an easy way to share resources across web components. - Dojo was one of the firs

In this podcast, Daniel Bryant sat down with Gareth Rushgrove, Director of Product Management at Snyk. Topics covered included Kubernetes as a platform, application abstractions, continuous delivery, and implementing good security practices in the cloud native space. Why listen to this podcast: - The value provided by Kubernetes depends on an organisation’s context. Kubernetes acts as both a series of lower-level building blocks for a platform, and also as a very powerful API for deploying and operating container-based applications. - Kubernetes provides several useful abstractions for engineers. For example, Pods, Deployments, and Services. However, Kubernetes doesn’t have an “application”-focused abstraction. Tools such as Helm and specifications like the Cloud Native Application Bundle (CNAB) are driving innovation in this space. - There is a large amount of open source Kubernetes tooling. This has been created by a range of vendors, groups, and individuals. Encouraging this di

- A Micro frontends is an approach to developing frontends that attempts to take some of the same benefits from Microservices and apply them to frontend development. - Microfront ends can be developed with different technologies and ownership of components on a single view. However, DAZN took a vertical approach to build them. Each Micro frontend is loaded into an app shell that offers an API for crosscutting concerns. Only one Micro frontend is loaded at a time into the app shell. - The ‘Inverse Conway Maneuver’ recommends evolving your team and organizational structure to create the architecture you want. - DAZN derisks deployments by using canaries implemented with Lambda at the Edge on Cloudfront. For code deployments, each of the Micro frontends can be introduced with a limited scope and then expanded once proven stable.

In this podcast, Daniel Bryant sat down with Zhamak Dehghani, principal consultant, member of technical advisory board, and portfolio director at ThoughtWorks. Topics discussed included: the motivations for becoming a data-driven organization; the challenges of adapting legacy data platforms and ETL jobs; and how to design and build the next generation of data platforms using ideas from domain-driven design and product thinking, and modern platform principles such as self-service workflows. Why listen to this podcast: - Becoming a data-driven organization remains one of the top strategic goals of many organizations. Being able to rapidly run experiments and efficiently analyse the resulting data can provide a competitive advantage. - There are several “architecture failure modes” within existing enterprise data platforms. They are centralized and monolithic. The composition of data pipelines are often highly-coupled, meaning that a change to the data format will require a cascade o

In this podcast, Daniel Bryant sat down with Brittany Postnikoff, a computer systems analyst specialising on the topics of robotics, embedded systems, and human-robot interaction. Topics discussed included: the rise of robotics and human-robot interaction within modern life, the security and privacy risks of robots used within this context, and the potential for robots to be used to socially engineer people. Why listen to this podcast: - Physical robots are becoming increasingly common in everyday life, for example, offering directions in airports, cleaning the floor in peoples’ homes, and acting as toys for children. - People often imbue these robots with human qualities, and they trust the authority granted to a robot. - Social engineering can involve the psychological manipulation of people into performing actions or divulging confidential information. This can be stereotyped by the traditional “con”. - As people are interacting with robots in a more human-like way, this can

In this podcast, Daniel Bryant sat down with Anurag Goel, Founder and CEO of Render. Topics covered included: the evolution of cloud platforms; simplifying developer experience; running large-scale workloads on Kubernetes; and the future of tooling and platforms within the cloud native computing space. Why listen to this podcast: - Render is aiming to be the next generation of cloud provider. Developers deploy and manage applications via a Platform-as-a-Service (PaaS) -like experience using custom simplified YAML configuration. - Render is built on top of Kubernetes, but the internals and configuration of this orchestration framework is not exposed to end user developers. - Many large scale usages of traditional cloud vendor platforms require the formation of specialised in-house “DevOps” teams. The provision of virtualisation and API-driven operation via the cloud providers was revolutionary, but it didn’t fundamentally change the existing platform paradigm. - Arguably platform

In this podcast, Daniel Bryant sat down with Greg Law, CTO at Undo. Topics discussed included: the challenges with debugging modern software systems, the need for “hyper-observability” and the benefit of being able to record and replay exact application execution; and the challenges with implementing the capture of nondeterministic system data in Undo’s LiveRecorder product for JVM-based languages that are Just-In-Time (JIT) compiled. Why listen to this podcast: - Understanding modern software systems can be very challenging, especially when the system is not doing what is expected. When debugging an issue, being able to observe a system and look at logging output is valuable, but it doesn’t always provide all of the information a developer needs. Instead we may need “hyper observability”; the ability to “zoom into” bugs and replay an exact execution. - Being able to record all nondeterministic stimuli to an application -- such as user input, network traffic, interprocess signals,

Today on The InfoQ Podcast, Wes Reisz speaks with CEO and founder of Solo Idit Levine. The two discuss the Three Pillars of Solo around Gloo, their API gateway, interoperability of service meshes (including the work on Service Mesh Interface), and on extending Envoy with Web Assembly (and the recently announced Web Assembly Hub). Why listen to this podcast: - Gloo is a Kubernetes-native ingress controller and API gateway. It’s built on top of Envoy and at its core is open source. - The Service Mesh Interface (SMI) is a specification for service meshes that runs on Kubernetes. It defines a common standard that can be implemented by a variety of providers. The idea of SMI is it’s an abstraction on top of service meshes, so that you can use one language to configure them all. - Autopilot is an open-source Kubernetes operator that allows developers to extend a service mesh control plane. - Lua has been commonly used to extend the service mesh data plane. Led by Google and the Envoy

Today, on The InfoQ Podcast, Wes Reisz talks with Gunnar Morling. Gunnar is a software engineer at RedHat and leads the Debezium project. Debezium is an open-source distributed platform for change data capture (CDC). On the show, the two discuss the project and many of its use cases. Additionally, topics covered on the podcast include bootstrapping, configuration, challenges, debugging, and operational modes. The show wraps with long term strategic goals for the project. Why listen to this podcast: - CDC is a set of software design patterns used to react to changing data in a data store. Used for things like internal changelogs, integrations, replication, and event streaming, CDC can be implemented leveraging queries or against the DB transaction log. Debezium leverages the transaction log to implement CDC and is extremely performant. - Debezium has mature source and sink connectors for MySQL, SQL Server, and MongoDB. In addition, there are Incumbating connectors for Cassandra, Ora

In this podcast, Daniel Bryant sat down with Kelsey Hightower, Staff Developer Advocate at Google. Topics covered included: the extensibility of Kubernetes, and why it has become the platform that other platforms are being built on top of; creating event-driven architectures and deploying these onto Function-as-a-Service (FaaS) platforms like the Kubernetes-based Knative and Google Cloud Run; and the benefits of learning, sharing knowledge, and building communities. Why listen to this podcast: - Kubernetes is a platform for building platforms. It may not be as opinionated as traditional Platform-as-a-Service (PaaS) offerings, but it has become popular due to its extensibility. There are PaaS-like solutions built on top of Kubernetes, such as OpenShift, Knative, and Cloud Run. - The creation of common interfaces within Kubernetes -- such as Custom Resource Definitions (CRDs), Container Networking Interface (CNI), and Container Runtime Interface (CRI) -- enabled the adoption of the

In this podcast, Daniel Bryant sat down with Katie Gamanji, Cloud Platform Engineer at Condé Nast International. Topics covered included: exploring the architecture of the Condé Nast Kubernetes-based platform; the importance of enabling self-service deployment for developers; and how the Kubernetes’ Federation API and Cluster API may enable more opportunities for platform automation. - Founded in the early 1900s, Condé Nast is a global media company that has recently migrated their application deployment platforms from individually-curated geographically-based platforms, to a standardised distributed platform based on Kubernetes and AWS. - The Condé Nast engineering team create and manage their own Kubernetes clusters, currently using CoreOS’s/Red Hat’s Tectonic tool. Self-service deployment of applications is managed via Helm Charts. - The platform team works closely with their “customer” developer teams in order to ensure their requirements are being met. - The Kubernetes Feder

In this podcast, Daniel Bryant spoke to Joseph Jacks, Founder of OSS Capital and the Open Core Summit, and discussed topics including the open source and open core models, innovations within open source hardware and the RISC-V instruction set architecture, and current opportunities for disruption using commercial open source software. Why listen to this podcast: - Recently, open source software and the open core business model have driven a lot of innovation and created a lot of value, particularly within the cloud “as-a-service” space. - There has been some disagreement between the open source and commercially-focused communities, for example, in relation to the licencing models and how value is captured. - The Open Core Summit (OCS) is a new conference focusing on the intersection of commercialisation and open source software that aims to facilitate discussion in this space. - Organisations building around open source software can potentially look at large cloud vendors as pa

In this special year-end wrap-up podcast Wes Reisz, Shane Hastie, Daniel Bryant, and Charles Humble discuss what we’ve seen in 2019 and speculate a little on what we hope to see in 2020. Topics include business agility and Teal, what it means to be an ethical engineer, bringing your whole self to work, highlights from QCon and InfoQ during 2019, the rise of Python, and progress in quantum computing. Why listen to this podcast: * Business agility is one of the major themes that the InfoQ team has seen emerge this year, with stronger emphasis on outcomes over outputs. We’ve also seen a growing interest in ethics and the ethical implications of the work we all do. * On the programming languages front the rise of Python continues, driven largely by its popularity in data science. * As Kubernetes cements its dominant position we’re hoping to see a simplification of the workflows associated with it, as well as in areas like observability. * There have been several big announcements in quan

Josh Wills, a software engineer working on data engineering problems at Slack, discusses the Slack data architecture and how they build and observe their pipelines. Josh, along with color commentary such as the move from IC to manager (and back), discusses recommendations, tips, tools, and lessons Slack engineering teams discovered while building products like Slack Search. The podcast covers machine learning, observability, data engineering, and general practices for building highly resilient software. Why listen to this podcast: - Slack has a philosophy of building only what they need. They have a don’t reinvent the wheel mindset. - Slack was originally a PHP monolith. Today, it is largely Hack-lang, HHVM, and several Java and Go binarys. On the data side, application logs are in Thrift (there is a plan to migrate to protobuf). Events are processed through a Kafka cluster that handles 100,000s of events per second. Everything is kept in S3 with a large Hive metastore. EMR is spu

In this podcast, Daniel Bryant sat down with Bryan Liles, senior staff engineer at VMware. Topics covered included: the challenges with deploying applications into Kubernetes, using the open source Octant tool to increase a user’s understanding of Kubernetes clusters, and how “serverless” technologies may influence the future approaches to building software. Why listen to this podcast: - Octant is a highly extensible platform for developers to better understand the complexity of Kubernetes clusters. Octant runs locally, using the local Kubernetes credentials. It currently displays information about a Kubernetes cluster and related applications as a web page. Soon this tool and resulting display will be provided as a standalone application. - The goal of Octant is to enable users to discover what they need to discover. The tool aims to provide context relevant to where a user is and what they are trying to achieve. The Octant plugin system allows integration with other tooling, such

Victor Dibia is a Research Engineer with Cloudera’s Fast Forward Labs. On today’s podcast, Wes and Victor talk about the realities of building machine learning in the browser. The two discuss the capabilities, limitations, process, and realities around using TensorFlow.js. The two wrap discussing techniques like Model distillation that may enable machine learning models to be deployed in smaller footprints like serverless. - While there are limitations in running machine learning processes in a resource constrained environment like the browser, there are tools like TensorFlow.js that make it worthwhile. One powerful use case is the ability to protect the privacy of a user base while still making recommendations. TensorFlow.js takes advantage of the WebGL library for its more computational intense operations. - TensorFlow.js enables workflows for training and scoring models (doing inference) purely online, by importing a model built offline with more tradition Python tools, and a hyb

In this podcast, Daniel Bryant spoke to Michelle Krejci, service engineer lead at Pantheon, about the Drupal and Wordpress webops-based company’s move to a microservices architecture. Michelle is a well-known conference speaker in the space of technical leadership and continuous integration, and she shared her lessons learned over the past four years of the migration. Why listen to this podcast: - The backend for the Pantheon webops platform began as a Python-based monolith with a Cassandra data store. This architecture choice initially enabled rapid feature development as the company searched for product/market fit. However, as the company found success and began scaling their engineering teams, the ability to add new functionality rapidly to the monolith became challenging. - Conceptual debt and technical debt greatly impact the ability to add new features to an application. Moving to microservices does not eliminate either of these forms of debt, but use of this architectural pa

In today’s podcast we sit down with Ryan Kitchens, a senior site reliability engineer and member of the CORE team at Netflix. This team is responsible for the entire lifecycle of incident management at Netflix, from incident response to memorialising an issue. Why listen to this podcast: - Top level metrics can be used as a proxy for user experience, and can be used to determine that issue should be alerted on an investigated. For example, at Netflix if the customer playback initiation “streams per second” metric declines rapidly, this may be an indication that something has broken. - Focusing on how things go right can provide valuable insight into the resilience within your system e.g. what are people doing everyday that helps us overcome incidents. Finding sources of resilience is somewhat “the story of the incident you didn’t have”. - When conducting an incident postmortem, simply reconstructing an incident is often not sufficient to determine what needs to be fixed; there is

In this podcast we sit down with Oliver Gould, co-founder and CTO of Buoyant. Oliver has a strong background in networking, architecture and observability, and worked on solving associated technical challenges at both Yahoo! and Twitter. Oliver is a regular presenter at cloud and infrastructure conferences, and alongside his co-founder William Morgan, you can often find them in the hallway track, waxing lyrical about service mesh -- a term they practically coined -- and trying to bring others along on the journey. Service mesh technology is still young, and the ecosystem is still very much a work in progress, but there have been several recent interesting developments within this space. One of these was the announcement of the service mesh interface (SMI) at the recent KubeCon EU in Barcelona. The SMI spec seeks to unlock service mesh integrators and implementers, as this can provide an abstraction that removes the need to bet on any single service mesh implementation. This can be goo

Today on the podcast, Bernd Rucker of Camunda talks about event sourcing. In particular, Wes and Bernd discuss thoughts around scalability, events, commands, consensus, and the orchestration engines Camunda implemented. This podcast is a primer on considerations between an RDBMS and event-driven systems. Why listen to this podcast: - An event-driven system is a more modern approach to building highly scalable systems. - An RDBMS system can limit throughput in scalability. Camunda was able to achieve higher levels of scale by implementing an event-driven system. - Command and events are often confused. Commands are actions that request something to happen. Events describe something that happened. Confusing the two causes confusion in application development of event-driven systems.

In this podcast we discuss a holistic approach to technical leadership, and Pat provides guidance on everything from defining target operating models, cultivating culture, and supporting people in developing the career they would like. There are a bunch of great stories, several book recommendations, and additional resources to follow up on. * Cultivating organisational culture is much like gardening: you can’t force things, but you can set the right conditions for growth. The most effective strategy is to communicate the vision and goals, lead the people, and manage the systems and organisational structure. * N26, a challenger bank based in Berlin has experienced hypergrowth over the past two years. Both the number of customers and the amount of employees have increased over threefold. This provides lots of opportunities for ownership of product and projects, and it creates unique leadership challenges. * A target operating model (TOM) is a blueprint of a firm's business vision that

Cilium is open source software for transparently securing the network connectivity between application services deployed using Linux container management platforms like Docker and Kubernetes. It is a CNI plugin that offers layer 7 features typically seen with a service mesh. On this week’s podcast, Thomas Graf (one of the maintainers of Cilium and co-founder of Isovalent) discusses the recent 1.6 release, some of the security questions/concerns around eBPF, and the future roadmap for the project. Why listen to this podcast: * Cilium brings eBPF to the Cloud Native World. It works across both layer 4 and a layer 7. While it started as a pure eBPF plugin, they discovered that just caring about ports was not enough from a security perspective. * Cilium went 1.0 about a year and a half ago. 1.6 is the most featured-packed release of Cilium yet. Today, it has around 100 contributors. * While Cilium can make it much easier to manage IPTables, Cilium overlaps with a service mesh in that it

The three pillars of observability are logs, metrics, and tracing. Most teams are able to handle logs and metrics, while proper tracing can still be a challenge. On this podcast, we talk with Yuri Shkuro, the creator of Jaeger, author of the book Mastering Distributed Tracing, and a software engineer at Uber, about how the Jaeger tracing backend implements the OpenTracing API to handle distributed tracing. Why listen to the podcast: - Jaeger is an open-source tracing backend, developed at Uber. It also has a collection of libraries that implement the OpenTracing API. - At a high level, Jaeger is very similar to Zipkin, but Jaeger has features not available in Zipkin, including adaptive sampling and advanced visualization tools in the UI. - Tracing is less expensive than logging because data is sampled. It also gives you a complete view of the system. You can see a macro view of the transaction, and how it interacted with dozens of microservices, while still being able to drill do

ROS is the Robotic Operating System. It’s been used by thousands of developers to prototype and create a robotic application. ROS can be found on robotics in warehouses, self-driving car companies, and on the International Space Station. Louise Poubel is an engineer working with Open Robotics. Today on the podcast, she talks about what it takes to develop software that moves in physical space, including the Sense, Think, Act Cycle, the developer experience, and architecture of ROS. Why listen to this podcast: - Writing code for robot development, you use the Sense, Think, Act Cycle. - ROS is an SDK for robotics. It provides a communication layer that enables data to flow between nodes that handle sensors, logic, and actuation. - ROS has two versions and has been around for twelve years. ROS 1 was entirely implemented in C. ROS 2 offers is a common C layer with implementations in many different languages, including Java, JavaScript, and Rust. - Released on a six-month cadence, Das

In this podcast we sit down with Matt Klein, software plumber at Lyft and creator of Envoy, and discuss topics including the continued evolution of the popular proxy, the strength of the open source Envoy community, and the value of creating and implementing standards throughout the technology stack. We also explore the larger topic of cloud natives platforms, and discuss the tradeoffs between using a simple and opinionated platform against something that is bespoke and more configurable, but also more complex. Related to this, Matt shares his thoughts on when and how to make the decision within an organisation to embrace technology like container orchestration and service meshes. Finally, we explore the creation of the new Envoy Mobile project. The goal of this project is to expand the capabilities provided by Envoy all the way out to mobile devices powered by Android and iOS. For example, most current user-focused traffic shifting that is conducted at the edge is implemented with co

On this podcast, we’re talking to Armon Dadgar, co-founder and CTO of HashiCorp. Alongside Mitchell Hashimoto, Armon founded HashiCorp over six years ago, and the company has gone from strength to strength, with their open source infrastructure product suite now consisting of Consul, Nomad, Vault and Terraform. We discuss the formation of the HashiCorp research division, and explore some of the computer science research underpinning Consul and Nomad. We also cover the challenges of supporting teams when they are looking to embrace new modes of working with dynamic infrastructure, and Armon introduces the new learn.hashicorp.com educational website and accompanying community and support forums. Why listen to this podcast: - There is a lot of fundamental computer science research that underpins the HashiCorp infrastructure workflow and configuration tooling. This helps to ensure that these mission-critical tools perform as expected, and enables sound reasoning about scaling these tech

In this episode recorded at QCon London 2019 Shane Hastie, Lead Editor for Culture & Methods, first spoke to Kingsley Davies about ethics and then with Cat Swetel about requisite variety and being mindful of the impact our decisions have for the future. Why listen to this podcast: • The need to explore the application of technology for good • The need for ethical standards in the technology industry • Data is the new oil and it is frequently used in ways that are not in the best interest of society • Other engineering professions have codes of conduct and ethical frameworks that are mandated as part of the education process, software engineering currently has very little • Ashby’s law of requisite variety – the more options that are available to a system, the more resilient the system is applies to all aspects of our socio-technical systems • We exist in the realm of ethics – we can’t just go to work and do what you’re told. Everything we do is a choice and our choices have a huge

The promise of Java has always been, “write once, run anywhere.” This was enabled through just-in-time compilation, which allowed developers to target a platform at compilation. But, this flexibility has given rise to comments like, “Java is slow.” What if you could compile Java to Native Code? On this podcast, we’re talking to Thomas Wuerthinger, a senior research director at Oracle Labs. Leading programming language implementation teams for Java, JavaScript, Ruby, and R. He is the architect of the Graal compiler and the Truffle self-optimizing runtime. Why listen to the podcast: - The GraalVM project was initially just a replacement for the JVM C2 just-in-time compiler, but has evolved to include support for multiple languages, as well as an ahead-of-time compiling mode. - Support for multiple languages can provide better performance for some languages, as well as making direct calls without inter-process communication. - With GraalVM’s AOT compilation, you can statically link s

On this podcast, Wes talks to John Xmas. Johnny works for Kasada, a company that offers a security platform to help ensure only your users are logging into your web applications. Johnny is a well-known figure in the security space. The two discuss common attack vectors, the OWASP Top 10, and then walk through what hackers commonly do attempting to compromise a system. The show is full of advice on protecting your systems including topics around Defense in Depth, Time-Based Security, two-factor authentication, logging/alerting, security layers, and much more. Why listen to this podcast: - While there are sophisticated web attacks out there that use things like PhantomJS or Headless Chome, the vast majority of the web application attacks are the same unsophisticated scripted attacks that you always hear about. These are simple scripts using tools like curl and BurpSuite with Python or JavaScript. These simple scripts are still incredibly effective. - OWASP Top 10 really hasn’t change

Today on the podcast, Wes talks with Mike Milinkovich, Executive Director of the Eclipse Foundation. The Eclipse Foundation was chosen to govern the evolution of Oracle’s Java EE to Jakarta EE. The two discuss the project, the recent news about issues with the javax namespace, the challenges around bundling a Java Runtime with Eclipse, and the path forward for Jakarta EE 9 and beyond. Why listen to this podcast: - Java EE, unlikely Java SE, has always been a multi-vendor ecosystem. It made sense for everyone for Oracle to invite their partners to be involved in the governance of the specification for Java EE for it to continue moving forward. This is the reason for moving Java EE into the Eclipse Foundation as Jakarta EE. - The current plan is for the Eclipse Foundation to get a copyright license to evolve the text of the specification and not a license to the trademarks of Java EE itself. - The javax namespace must remain as is. For it to be evolved, a different namespace must be

Ludwig is a code-free deep learning toolbox originally created and open sourced by UberAI. Today, on the podcast the creator of Ludwig Piero Molino and Wes Reisz discuss the project. The two talk about how the project works, its strengths, it’s roadmap, and how it’s being used by companies inside (and outside) of Uber. They wrap by discussing path ahead for Ludwig and how you can get involved with the project. Why listen to this podcast: • Uber AI is the research and platform team for everything AI at the company with the exception of self-driving cars. Self-driving cars are left to Uber ATG. • Ludwig allows you to specify a Tensorflow model in a declarative format that focuses on your inputs and outputs. Ludwig then builds a model that can deal with those types of inputs and outputs without a developer explicitly specifying how that is done. • Because of Ludwig’s datatype abstraction for inputs and outputs, there is a huge range of applications that can be created. For example, an i

Ben Sigelman is the CEO of Lightstep and the author of the Dapper paper that spawned distributed tracing discussions in the software industry. On the podcast today, Ben discusses with Wes observability, and his thoughts on logging, metrics, and tracing. The two discuss detection and refinement as the real problem when it comes to diagnosing and troubleshooting incidents with data. The podcast is full of useful tips on building and implementing an effective observability strategy. Why listen to this podcast: - If you’re getting woke up for an alert, it should actually be an emergency. When that happens, things to think about include: when did this happen, how quickly is it changing, how did it change, and what things in my entire system are correlated with that change. - A reality that seems to be happening in our industry is that we’re coupling the move to microservices with a move to allowing teams to fully self-determine technology stacks. This is dangerous because we’re not at t

- Web Assembly (wasm) is a set of instructions or a low-level byte code that is a target for higher level languages. It was added to the browser because it was a portion of the web platform that many felt was just missing. - Wasm is still a young technology. It performs really well for computationally intensive applications and also offers performance consistency (because it lacks a garbage collector). - Bootstrapping an application using the Rust toolchain looks like: pull down a template, export a function using an attribute (defines that you want to access this function from JavaScript), and run a tool called wasm-pack (compiles it into Web Assembly and then runs a tool called wasm-bindgen that generated Rust types for Wasm). Then you can talk to that binary as if it was written in JavaScript in your code. - Cloudflare workers allow JavaScript that you might have written for a server to be written and distributed at the application edge (or close to the end user). It uses a simil

Bryan Cantrill is the CTO of Joyent and well known for the development of DTrace at Sun Microsystems. Today on the podcast, Bryan discusses with Wes Reisz a bit about the origins of DTrace and then spends the rest of the time discussing why he feels Rust is the “biggest development in systems development in his career.” The podcast wraps with a bit about why Bryan feels we should be rewriting parts of the operating system in Rust. Why listen to the podcast: • DTrace came down to a desire to use Dynamic Program Text Modification to instrument running systems (much like debuggers do) and has its origins to when Bryan was an undergraduate. • When a programming language delivers something to you, it takes it from you in the runtime. The classic example of this is garbage collection. The programming language gives you the ability to use memory dynamically without thinking of how the memory is stored in the system, but then it’s going to exact a runtime cost. • One of the issues with C is

Duncan Macgregor speaks with Wes Reisz about the work being done on the experimental Graal Compiler. He talks about the use cases and where the new JIT compiler excels really well (compared to C2). In addition, Duncan talks about the relationship of Graal to Truffle. The two then discuss a language Duncan works on at OracleLabs (TruffleRuby) that is being implemented on the stack. Finally, the podcast wraps with a discussion of Project Loom and its relationship to TruffleRuby and Graal. Why listen to this podcast: - Graal is a replacement for the JVM’s C2 JIT compiler. It was tracked with JEP 295 (Ahead-of-Time Compilation) and included in Java 9. As of Java 10, Graal is experimental for the Linux x64 platform. - Graal is written in Java and excels at implementing code that takes a functional approach to solving problems (such as Scala). It can also offer improvements / optimizations for other languages (including other non-traditional JVM languages such as C and Ruby). - Truffle is

Today on The InfoQ Podcast, Wes talks with Rod Johnson. Rod is famously responsible for the creation of the Spring Framework. The two talk about the early years of the framework and provides some of the history of its creation. After discussing Spring, Wes and Rod discuss languages he’s been involved with since Java (these include Scala and TypeScript). He talks a bit about what he liked (and didn’t like) about each. Finally, the two wrap by discussing Atomist and how they’re trying to change the idea of software delivery from a statically defined pipeline (located in individual repositories) to an event hub that drives a series of actions for software delivery. He describes this as creating an API for your software. Why listen to this podcast: - The initial origins of the Spring Framework really came about through a process of trying to write a really great book about J2EE in 2002. It was through that process that Rod Johnson found he felt there was a better way and ultimately lead

Today on The InfoQ Podcast, Wes talks with Katharine Jarmul about privacy and fairness in machine learning algorithms. Katharine discusses what’s meant by Ethical Machine Learning and some things to consider when working towards achieving fairness. Katharine is the Co-Founder at KIProtect a machine learning security and privacy firm based in Germany and is one of the three keynotes at QCon.ai. Why listen to this podcast: - Ethical machine learning is about practices and strategies for creating more ethical machine learning models. There are many highly publicized/documented examples of machine learning gone awry that show the importance of the need to address ethical machine learning. - Some of the first steps to prevent bias in machine learning is awareness. You should take time to identify your team goals and establish fairness criteria that should be revisited over time. This fairness criteria then can be used to establish the minimum fairness criteria allowed in production. - Law

Today on The InfoQ Podcast, Wes Reisz speaks with Grady Booch. Grady is well known as the co-creator of UML, an original member of the design patterns movement, and now work he’s doing around Artificial Intelligence. On the podcast today, the two discuss what today’s reality is for AI. Grady answers questions like what does an AI mean to the practice of writing software and around how he seems it impact delivering software. In addition, Grady talks about AI surges (and winters) of over the years, the importance of ethics in software, and host of other related questions. Why listen to this podcast: - There have been prior ages of AI that has lead to immediate winters of where reality set in. It stands to reason, there will be a version of an AI winter that follows today’s excitement around deep learning. - AIs are beginning to look at the code for testing edge cases in software and do things such as looking over your shoulder and identifying patterns in the code that you write. -

Today on The InfoQ Podcast, Wes talks with Joe Beda. Joe is one of the co-creators of Kubernetes. What started in the fall of 2013 with Craig McLuckie, Joe Beda, and Brendan Burns working on cloud infrastructure has become the default orchestrator for cloud native architectures. Today on the show, the two discuss the recent purchase of Heptio by VMWare, the Kubernetes Privilege Escalation Flaw (and the response to it), Kubernetes Enhancement Proposals, the CNCF/organization of Kubernetes, and some of the future hopes for the platform. Why listen to this podcast: - Heptio, the company Joe and Craig McLuckie co-founded, viewed themselves as not a Kubernetes company, but more of a cloud native company. Joining VMWare allowed the company to continue a mission of helping people decouple “moving to cloud/taking advantage of cloud” patterns (regardless of where you’re running). - Re:Invent 2017 when EKS was announced was a watershed moment for Kubernetes. It marked a time where enough cu

Today on the InfoQ Podcast, Wes speaks with ThirdLove’s Megan Cartwright. Megan is the Director of Data Science for the personalized bra company. In the podcast, Megan first discusses why their customers need a more personal experience and how their using technology to help. She focuses quite a bit of time in the podcast discussing how the team got to an early MVP and then how they did the same for getting to an early machine learning MVP for product recommendations. In this later part, she discusses decisions they made on what data to use, how to get the solution into production quickly, how to update/train new models, and where they needed help. It’s a real early stage startup story of a lean team leveraging machine learning to get to a practical recommendations solution in a very short timeframe. Why listen to this podcast: - The experience for women selecting bras is poor experience characterized by awkward fitting experiences and an often uncomfortable product that may not even

Lynn Langit is a consulting cloud architect who holds recognitions from all three major cloud vendors on her contributions to their respective communities. On today’s podcast, Wes talks with Lynn about a concept she calls 25% time and a project it led her to become involved within genomic research. 25% time is her own method of learning while collaborating with someone else for a greater good. A recent project leads her to become involved with the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia. Through cloud adoption and some lean startup practices, they were able to drop the run time for a machine learning algorithm against a genomic dataset from 500 hours to 10 minutes. Why listen to this podcast: - 25% time is a way to learn, study, or collaborate with someone else for a greater good. It’s unbilled time in the service of offers. Using the idea of 25% time along with some personal events that occurred in her life, Lynn became involved with genomi

In this podcast Charles Humble and Wes Reisz talk about autonomous vehicles, GDPR, quantum computing, microservices, AR/VR and more. * Waymo vehicles are now allowed to be on the road in California running fully autonomous; they seem to be a long way ahead in terms of the number of autonomous miles they’ve driven, but there are something like 60 other companies in California approved to test autonomous vehicles. * It seems reasonable to assume that considerably more regulation around privacy will appear over the next few years, as governments and regulators grapple with not only social media but also who owns the data from technology like AR glasses or self-driving cars. * We’ve seen a huge amount of interest in the ethical implications of technology this year, with Uber getting into some regulatory trouble, and Facebook being co-opted by foreign governments for nefarious purposes. As software becomes more and more pervasive in people's lives the ethical impact of what we all do bec

On this week’s podcast, Wes Reisz talks with Brian Goetz. Brian is the Java Language Architect at Oracle. The two start with a discussion on what the six-month cadence has meant to the teams developing Java. Then move to a review of the features in Java 9 through 12. Finally, the two discuss the longer-term side projects (such as Amber, Loom, and Valhalla) and their role in the larger release process for the JDK. * The JVM’s sixth-month cadence changed the way the JDK is delivered and planned. While it definitely provides more rapid delivery at expected intervals, the release train approach turned out to also improve flexibility and efficiency. * Oracle JDK and OpenJDK are almost identical. Most of the JDK distributions are forks from OpenJDK with different bug fixes and backports applied. So the difference between the distributions now is largely which bug fixes are picked up. * Local Variable inference (which was released as part of Java 10) illustrated the tension on making changes

This week on the InfoQ Podcast, Wes Reisz talks to Tanya Reilly (Principal Engineer at Squarespace and previously a staff SRE at Google). Tanya discusses her research into how the fire code evolved in New York and draws on some of the parallels she sees in software. Along the way, she discusses what it means to be an SRE, what effective aspects of the role might look like, and her opinions on what we as an industry should be doing to prevent disasters. This podcast features discussion on paved roads, prevention, testing, firefighting (in software), and reliability questions to ask throughout the software lifecycle. Why listen to this podcast: - Teams increasingly are responsible for the entire software lifecycle. When this happens, they think about the software differently because they know their the ones that will get paged if it fails. This idea is at the core of the “You Build It, You Run It” philosophy in DevOps. - The role of SRE is to define how to do things in a really relia

On today’s podcast, Wes Reisz talks with Jason Maude of Starling Bank. Starling Bank is a relatively new startup in the United Kingdom working in the banking sector. The two discuss the architecture, technology choices, and design processes used at Starling. In addition, Maude goes into some of the realities of building in the cloud, working with regulators, and proven robustness with practices like chaos testing. Why listen to this podcast: - Starling Bank was created because the government lowered the barrier to entry for banking startups in reaction to previous industry bailouts. - The system is composed of around 19 applications hosted on AWS and running Java and backed by a PostgreSQL database. - These applications are not monolithic but are focused around common functionality (such as a Card or Payment Service). - Java was chosen primarily because of its maturity and long term viability/reliability in the market. - The heart of Starling is every action the system takes hap

Martin Fowler chats about the work he’s done over the last couple of years on the rewrite of the original Refactorings book. He discusses how this thought process has changed and how that’s affected the new edition of the book. In addition to discussing Refactors, Martin and Wes discuss his thoughts on evolutionary architecture, team structures, and how the idea of refactors can be applied in larger architecture contexts. Why listen to this podcast: - Refactoring is the idea of trying to identify the sequence of small steps that allows you to make a big change. That core idea hasn’t changed. - Several new refactorings in the book deal with the idea of transforming data structures into other data structures, Combine Functions into Transform for example. - Several of the refactorings were removed or not added to the book in favor of adding them to a web edition of the book. - A lot of the early refactorings are like cleaning the dirt off the glass of a window. You just need them

In June of this year, Consul 1.2 was released. The release expanded Consul’s capability around service segmentation (controlling who and how services connect East and West). On this week’s podcast, Wes and Mitchell discuss Consul in detail. The two discuss Consul’s design decisions around focusing on user space networking, layer 4 routing, Go, Windows’ performance characteristics, the roadmap for eBPF on Linux, and an interesting feature that Consul implements called Network Tomography. The show wraps with Mitchell’s discussion on some of the research that Hashicorp is doing around machine learning and security with Consul. Why listen to this podcast: - Consul is first and foremost a centralized service registry that provides discovery. While it has a key-value store, it is Consul’s least important feature. With the June release (1.2), Consul entered more into the space of a service mesh with the focus on service segmentation (controlling how you connect and who can connect). - Hashi

On the podcast this week Charles Humble talks to Camille Fournier about running a platform team, how her current role differs from the CTO role she had a Rent the Runway, the skills developers need to acquire as they move from engineering to management positions, tends like Holacracy, and her book "The Manager's Path" Why listen to this podcast: - When looking for platform engineers Camille looks for people who understand what it takes to build and run distributed systems - network, availability, data - and customer empathy. - The team needs to be focussed on taking the time do build robust software for operational excellence. - The technical skills were different at Rent the Runway - these would tend to be more full-stack engineers who worked in a more iterative way. - Much of what we do at work is really about human relationships. One thing about relationships is that they tend to be better when you have one on one conversations with people on our regular basis. A lot of the

On this week’s podcast, Wes Reisz talks to Emmanuel Ameisen, head of AI for Insight Data Science, about building a semantic search system for images using convolution neural networks and word embeddings, how you can build on the work done by companies like Google, and then explores where the gaps are and where you need to train your own models. The podcast wraps up with a discussion around how you get something like this into production. Why listen to this podcast: - A common use case is the ability to search for similar things - I want to find another pair of sunglasses like these, or I want a cat that looks like this picture, or even a tool like Google’s Smart Reply, can all be considered broadly the domain of semantic search. - For image classification you generally want a convolutional neural network. You typically use a model pre-trained with a public data set like Imagenet pre-trained to generate embeddings, using the pre-trained model up to the penultimate layer, and stori

On this week’s podcast, Wes Reisz talks with Ben Kehoe of iRobot. Ben is a Cloud Robotics Research Scientist where he works on using the Internet to allow robots to do more and better things. AWS and, in particular, Lambda is a core part of cloud enabled robots. The two discuss iRobot’s cloud architecture. Some of the key lessons on the podcast include: thoughts on logging, deploying, unit/integration testing, service discovery, minimizing costs of service to service calls, and Conway’s Law. Why listen to this podcast: - The AWS Platform, including services such as Kinesis, Lambda, and IoT Gateway were key components in allowing iRobot to build out everything they needed for Internet-connected robots in 2015. - Cloud-enabled Roombas talk to the cloud via the IoT Gateway (which is MQQT) and are able to perform large file uploads using mutually authenticated certificates signed via an iRobot Certificate Authority. The entire system is event-driven with lambda being used to perform ac

Vaughn Vernon is thought-leader in the space of reactive software and Domain Driven Design (DDD). Vaughn has recently released a new open source project called vlingo. The platform is designed to support DDD at the framework and toolkit level. On today’s podcast, Vaughn discusses what the framework is all about, why he felt it was needed, and some of the design decisions made in developing the platform, including things like the architecture, actor model decisions, clustering algorithm, and how DDD is realized with the framework. Why listen to this podcast: - Vlingo is an open source system for building distributed, concurrent, event-driven, reactive microservices that supports (at the framework level) Domain Driven Design. - The platform is in the early stages. It runs on the JVM. There is a port to C#. All code is pushed up stream. - The platform uses the actor model and all messages are sent in a type-safe way. - Vlingo supports clustering and uses a bully algorithm to achieve

On today’s podcast, Justin Cormack discusses how the modern operating system is being decomposed with toolkits and libraries such as LinuxKit, eBPF, XDP, and what the kernel space service mesh Cilium is doing. Wes Reisz and Justin Cormack also discuss how Cilium differs from service meshes like an Istio, Linkerd2 (previously Conduit), or Envoy. Justin is a systems engineer at Docker. He previously was working with unikernels at Unikernel Systems in Cambridge before being acquired by Docker. (edited) *Key Takeaways:* * LinuxKit is an appliance way of thinking about your operating system and is gaining adoption. There are contributions now from Oracle, Cloudflare, Intel, etc. Docker has seen interesting use cases such as customers running LinuxKit on large cloud providers directly on bare metal (more on this coming soon). * The operating system of today is really unchanged since the Sun workstation of the 90’s. Yet everything else about software has really changed such as automation, bu

Probabilistic Programming has been discussed as a programming paradigm that uses statistical approaches to dealing with uncertainty in data as a first class construct. On today’s podcast, Wes talks with Mike Lee Williams of Cloudera’s Fast Forward Labs about Probabilistic Programming. The two discusses how Bayesian Inference works, how it’s used in Probabilistic Programming, production-level languages in the space, and some of the implementations/libraries that we’re seeing. Key Takeaways * Federated machine learning is an approach of developing models at an edge device and returning just the model to a centralized location. By taking the averages of the edge models, you can protect privacy and distribute processing of building models. *Probabilistic Programming is a family of programming languages that make statistical problems easier to describe and solve. *It is heavily influenced by Bayesian Inference or an approach to experimentation that turns what you know before the experiment

Wes Reisz sits down and chats with Uncle Bob about The Clean Architecture, the origins of the Software Craftsperson Movement, Livable Code, and even ethics in software. Uncle Bob discusses his thoughts on how The Clean Architecture is affected by things like functional programming, services meshes, and microservices. Why listen to this podcast: * Michael Feathers wrote to Bob and said if you rearrange the order of the design principles, it spells SOLID. * Software Craftsperson should be used when you talking about software craftsmanship in a gender-neutral way to steer clear of anything exclusionary. * Clean Architecture is a way to develop software with low coupling and is independent of implementation details. * Clean Architecture and Domain Driven Design (DDD) are compatible terms. You would find the ubiquitous language and bounded context of DDD at the innermost circles of a clean architecture. * Services do not form an architecture. They form a deployment pattern that is a way o

Arun Gupta discusses with Wes Reisz some of the container-focused services that AWS offers, including differentiating ECS and EKS. Arun goes into some detail the role that Amazon Fargate plays and goals behinds EKS. Arun wraps ups discussing some of the open source work that AWS has recently been doing in the container space. Why liste to this podcast: - ECS & EKS are both managed control planes; Amazon Fargate is a technology used to provision clusters. - ECR is the Amazon Container registry (similar to the Docker Registry). - EKS is an opinionated why of running a Kubernetes cluster on AWS. It is a highly available managed control plane available on US East 1 and US West 2 - EKS uses a split account. The control plane runs in an Amazon account and the workers run in customer’s account. - Upstream compatibility is a core tenant of EKS.

In this podcast Wes Reisz is talking to Anastasiia Voitova, known as @vixentael in the security communities. She started her career as a mobile application developer, and in recent years has moved to focus mainly on designing and developing graphics software. We’re going to talk about cryptography, how to design libraries to be usable by developers, and designing cryptographic libraries. We’ll also discuss about her talk from the recent QCon New York , called “Making Security Usable”. Why listen to this podcast: - Choosing a good encryption algorithm isn’t enough - the parameters need to be chosen carefully as well - Algorithms like MD5 should not be used for hashing any more - Security is not just the encryption layer - it is the design of the whole system - Backups should be encrypted as well - Logs may contain sensitive GDPR data and need to be processed accordingly More on this: Quick scan our curated show notes on InfoQ https://bit.ly/2yRWdQc You can also subscribe to the

On today’s podcast, Wes Reisz talks to Matt Klein about Envoy. Envoy is a modern, high performance, small footprint edge and service proxy. While it was originally developed at Lyft (and still drives much of their architecture), it is a fully open source driven project. Matt addresses on this podcast what he sees as the major design goals of Envoy, answers questions about a sidecar performance impact, discusses observability, and thinks out loud on the future of Envoy. Why listen to this podcast: - Envoy’s goal is to abstract the network from application programmers. It’s really about helping application developers focus on building business logic and not on the application plumbing. - Envoy is a large community driven project, not a cohesive product that does one thing. It can be used as a foundational building blocks to extend into a variety of use cases, including as an edge proxy, as a service mesh sidecar, and as a substrate for building new products. - While there is performanc

On this podcast, Pam Selle (an engineer for IOPipe who builds tooling for serverless observability) talks about the case for serverless and the challenges for developing observability solutions. Some of the things discussed on the podcast include tips for creating boundaries between serverless and non-serverless resources and how to think of distributed tracing in serverless environments. Why listen to this podcast: - Coca Cola was able to see a productivity gain of 29% by adopting serverless (as measured by the amount of time spent on business productivity applications). - Tooling for serverless is often a challenge because resources are ephemeral. To address the ephemeral nature of serverless, you need to think about what information you will need to log ahead of time. - Monitoring should focus on events important to the business. - Build barriers between serverless and flat scaling non-serverless resources to prevent issues. Queues are an example of ways to protect flat scaling re

The Serverless Framework is quickly becoming one of the more popular frameworks used in managing serverless deployments. David Wells, an engineer working on the framework, talks with Wes Reisz about serverless adoption and the use of the open source Serverless Framework. On this week’s podcast, the two dive into what it looks like to use the tool, the development experience, why a developer might want to consider a tool like the serverless framework, and finally wraps up with what the tool offers in areas like CI/CD, canaries, and blue/green deployment. Why listen to this podcast: - Serverless allows you to focus on the core business functionality and less on the infrastructure required to run your systems. - Serverless Framework allows you to simplify the amount of configuration you need for each cloud provider (for example, you can automate much of the configuration required for CloudFormation with AWS) - Serverless Framework is an open source CLI tool that supports all major

In this podcast Wes Reisz talks to Colin Eberhardt, the Technology Director at Scott Logic, talks about what WebAssembly (WASM) is, a bit of the history of JavaScript, information about WebAssembly, and plans for WebAssembly 2.0 including the threading model and GC. Why listen to this podcast: - WebAssembly brings another kind of virtual machine to the browser that is a much more low-level language. - One of the goals of WebAssembly is to make a new assembly language that is a compilation target for a wide range of other languages such as C++, Java, C# and Rust. C++ is highly mature, Rust is maturing rapidly. Java and C# are a little further behind because of the lack of garbage collection support in WebAssembly. At some point in the future WebAssemblywill have it’s own garbage collection perhaps by using the Javascript garbage collector. - At runtime you use JavaScript to invoke functions that are exported by your WebAssembly instance. It should be noted that at the moment there

Martin Thompson discusses consensus in distributed systems, and how Aeron uses Raft for clustering in the upcoming release. Martin is a Java Champion with over 2 decades of experience building complex and high-performance computing systems. He is most recently known for his work on Aeron and Simple Binary Encoding (SBE). Previously at LMAX he was the co-founder and CTO when he created the Disruptor.  * Aeron is a messaging system designed for modern multi-core hardware. It is highly performant with a first class design goal of making it easy to monitor and understand at runtime. The product is able to simultaneously achieve the lowest latency and highest throughput of any messaging system available today. Why listen to this podcast: * Aeron uses a binary format on the wire rather than a text based protocol. This is largely done for performance reasons. Text is commonly used in messaging to make debugging simpler but the debugging problem can be solved using tools like Wireshark

In this podcast, recorded live at QCon.ai, Principal Technical Advisor & QCon Chair Wes Reisz and InfoQ Editor-in-chief Charles Humble chair a panel discussion with Stephanie Yee, data scientist at StitchFix, Matei Zaharia, professor of computer science at Stanford and chief scientist at Data Bricks, Sid Anand, chief data engineer at PayPal, and Soups Ranjan, director of data science at CoinBase. Why listen to this podcast: - Before you start putting a data science team together make sure you have a business goal or question that you want to answer;  If you have a specific question, like increasing lift on a metric, or understanding  customer usage patterns, you know where you can get the data from, and you can then figure out how to organise that data. - You need to make sure you have the right culture for the team - and find people who are excited about solving the business problems and be interested in it.  Also look at the environment you are going to provide.  - Your first hi

On this week’s podcast, Danny Yuan, Uber’s Real-time Streaming/Forecasting Lead, lays out a thorough recipe book for building a real-time streaming platform with a major focus on forecasting. In this podcast, Danny discusses everything from the scale Uber operates at to what the major steps for training/deploy models in an iterative (almost Darwinistic) fashion and wraps with his advice for software engineers who want to begin applying machine learning into their day-to-day job. Why listen to this podcast: * Uber processes 850,000 - 1.3 million messages per second in their streaming platform with about 12 TB of growth per day. The system’s queries scan 100 million to 4 billion documents per second. * Uber’s frontend is mobile. The frontend talks to an API layer. All services generate events that are shuffled into Kafka. The real-time forecasting pipeline taps into Kafka to processes events and stores the data into Elasticsearch. * There is a federated query layer in front of Elasti

Sander Mak and Wes Reisz discuss the Java module system and how adoption is going. Topics discussed on this podcast include Java modularity steps / migrations, green field projects, some of the concerns that caused the EC to initially vote no on Java 9, and a new tool for building custom JREs called JLink. Additionally, as Java 10 was recently released a short bit at the end was added to discuss some of the latest news with Java. Why listen to this podcast: • People quickly moved to Java 8 because of features like Streams and Lambdas. Java 9 has a different story around modularity and application architecture. Adoption is slower and more intentional. • Migrating large codebases to use modularity is hard. Many of the projects using modules are greenfield, and those large codebases that are moving now are most often using the classpath. • Jlink is a new command line tool released with Java 9. It allows developers to create their own lightweight, customized JRE for a module-based Java a

Jendrik Joerdening and Anthony Navarro describe how a team of 18 Udacity students entered a self-racing car event   They had very limited experience of building autonomous control systems for vehicles and had just 6 weeks to do it with only 2 days with the physical car.  They describe the architecture, how they co-ordinated a very diverse team, and how they trained the models. Why listen to this podcast: - Last year a team of 18 Udacity Self-Driving Cars students competed at the 2017 Self Racing Cars event held at Thunderhill Raceway in California. - The students had all taken the first term of a three term program on Udacity which covers computer vision and deep learning techniques. - The team was extremely diverse.  They co-ordinated the work via Slack with a team in 9 timezones and 5 different countries.   - The team developed a neural network using Keras and Tensorflow which steered the car based on the input from just one front-facing camera in order to navigate all turns on

On this podcast, we talk with Andrea Magnorsky, who is a tech lead at Goodlord on their engineering squads; she has a background in Scala, C#, and organised conferences. Today we’ll be talking about paradigm shifts. Why listen to this podcast: * A programming paradigm has a loose definition. It’s just about finding a way of doing things. * There are a number of different ways to think about problems - and different paradigms do this in different ways. * To shift paradigms, you have to un-learn some of your instincts. * When adopting a new paradigm if people don’t want to learn anything, then they won’t. * Multiple paradigms help you apply different ways of thinking about solutions to problems because solutions vary across languages. * Quick ways to start gaining knowledge and adoption for new languages are to use a new language as a test harness for your existing code.

On this podcast, Anne Currie joins the tech ethics discussion started on the Theo Schlossnagle podcast from a few weeks ago. Wes Reisz and Anne discuss issues such as the implications (and responsibilities) of the massive amount of scale we have at our fingertips today, potential effects of GDPR (EU privacy legislation), how accessibility is a an example of how we could approach tech ethics in software, and much more. Why listen to this podcast: - Ethics in software today is particularly important because of the scale we have available with cloud native architectures. - Accessibility offers a good approach to how we can evolve the discussion on tech ethics with aspects that include both a carrot and a stick. - Bitcoin mining power consumption is an example of something we never considered to have such negatives. - The key to establishing what we all should and shouldn’t be doing with tech ethics is to start conversations and share our lessons with each other. If you want to find out

This week on The InfoQ Podcast Wes Reisz talks with the CTO of Bouyant Oliver Gould. Bouyant is the maker the LinkerD Service Mesh and the recently released Conduit. In the podcast, Oliver defines a service mesh, clarifies the meaning of the data and control plane, discusses what a Service Mesh can offer a Microservice application owners, and, finally, discusses some of the considerations they took into account developing Conduit. Why listen to this podcast: - Service mesh is dedicated infrastructure that handles interservice communication. - There are two components to a service mesh: the data plane handles communication and the control plane is about policy and config. - LinkerD and Conduit are two open service meshes made by Bouyant. Conduit has a small memory footprint and provides a convention over configuration approach to service mesh deployment. - Adopting Rust (language used for implementing the data plane in Conduit) requires thinking of memory differently, and the best way

This week's podcast features a chat with Theo Scholossnagle. Theo is the CEO of Circonus and co-chairs the ACM Queue. In this podcast, Theo and Wes Reisz chat about the need for ethical software, and how we as technical leaders should be reasoning about the software we create. Theo says, "it's not about the absence of evil, it's about the presence of good." He challenges us to develop rigor around ethical decisions we make in software just as we do for areas like security. With the incredible implications of machine learning and AI in our future, this week's podcast touches on topics we should all consider in the systems we create. Why listen to this podcast: - The ubiquitous society impact of computers is surfacing the need for deeper conversations on software ethics. - Ethics are a set of constructs and constraints to help us reason about right and wrong. - Algorithmic interpretability of models can be difficult to reason about; however, accountability for algorithms can be enfo

On this week’s podcast, Wes Reisz talks with Chris Swan. Chris is the CTO for the global delivery organisation at DXC Technology. Chris is well versed in DevOps, Infrastructure, Culture, and what it means to put all these together. Today’s topics include both DevOps and NoOps, and what Chris calls LessOps, what Operations means in a world of Serverless, where he sees Configuration Management, Provisioning, Monitoring and Logging heading. The podcast then wraps talking about where he sees validating code in a serverless deployment, such as canaries and blue-green deployments. Why listen to this podcast: * Serverless still requires ops - even if the ops aren’t focused on the technology * Even with minimal functions, the amount of configuration may exceed it by a factor of three * Disruptive services often move the decimal point * ML is the ability to make the inferences and AI is the ability to make decisions based on those inferences More on this: Quick scan our curated show notes o

This week’s podcast features a chat with Vitor Olivier. Vitor is a partner at NuBank (a technology-centric bank in Brazil). This podcast hits on topics from several of Nubank’s recent QCon talks and includes things like: Nubank’s stack, functional programming, event sourcing, defining service boundaries, recommendations on reasoning about services, tips (or tweaks) on the second iteration of their initial architecture and more. Why listen to this podcast: - Property-based testing and Schemas (or Clojure.Spec)are complementary. - Clojure’s functional nature and Datomic’s features are a match for Nubank’s requirements. - A (micro)service needs to be able to create the full representation of the core feature it’s handling. - GraphQL is useful to abstract away the distributed system complexity from the mobile (or frontend) developers. - Nubank’s uses a combination of monitoring and sanity checks in real time at various level to keep systems consistent. - Once an invariant is broken,

In this podcast Charles Humble and Wes Reisz talk about Java 9 and beyond, Kotlin, .NET Core 2, the surge in interest in organisational culture, quantum computing and more. Why listen to this podcast: - Java had a big year with Java 9 shipping, Java EE going open-source and moving to Eclipse as EE4J, and IBM open-sprucing J9.  From next year the platform will also be on a bi-annual release cycle with the next two versions (expected to be Java 10 and 11) both shipping during 2018. - Kotlin joined Scala, Clojure, and Groovy as a strong alternative language for the JVM particularly for mobile where it was buoyed by Google’s official blessing of it as a language for Android development at Google IO. - On InfoQ we also saw a big surge in interest around .NET linked to .NET Core 2, and at both InfoQ and at QCon San Fransisco we also saw an upsurge in interest around organizational culture with one of the culture tracks (the Whole Engineer) moving to one of the larger rooms. - We starte

In this podcast, Deam Wampler discusses fast data, streaming, microservices, and the paradox of choice when it comes to the options available today building data pipelines. Why listen to this podcast: * Apache Beam is fast becoming the de-facto standard API for stream processing * Spark is great for batch processing, but Flink is tackling the low-latency streaming processing market * Avoid running blocking REST calls from within a stream processing system - have them asynchronously launched and communicate over Kafka queues * Visibility into telemetry of streaming processing systems is still a new field and under active development * Running the fast data platform is easily launched on an existing or new Mesosphere DC/OS runtime More on this: Quick scan our curated show notes on InfoQ http://bit.ly/2BYTMbI You can also subscribe to the InfoQ newsletter to receive weekly updates on the hottest topics from professional software development. bit.ly/24x3IVq Subscribe: www.youtube.com/

In this podcast, we are talking to Tyler Akidau, a senior engineer at Google, who leads the technical infrastructure and data processing teams in Seattle, and a founding member of the Apache Beam PMC and a passionate voice in the streaming space. This podcast will cover data streaming and the 2015 DataFlow Model streaming paper [http://www.vldb.org/pvldb/vol8/p1792-Akidau.pdf] and much of the concepts covered, such as why dealing with out-of-order data is important, event time versus processing time, windowing approaches, and finally preview the track he is hosting at QConf SF next week. Why listen to this podcast: - Batch processing and streaming aren’t two incompatible things; they are a function of different windowing options. - Event time and processing time are two different concepts, and may be out of step with each other. - Completeness is knowing that you have processed all the events for a particular window. - Windowing choice can be answered from the what, when, where,

In this podcast, Wes talks to Guy Podjarny (Founder/CEO Synk). The two discuss the space between open source software and third-party dependencies, including a discussion of the Equifax hack (and what we can learn from it), the role of serverless architectures today (and what it means to application surface area), and then finally they wrap with security hygiene best practices with OSS and serverless. Why listen to this podcast: - The majority of security vulnerabilities that exist in applications today comes from vulnerable third-party libraries, rather than the application’s own code. - An application shouldn’t permit total leak of all data because of a single vulnerability - defence in depth is important. - Equifax couldn’t have failed more spectacularly in the way they handled it. - The Equifax hack serves as a wake-up call to pay attention to vulnerabilities in dependencies. - If your build system breaks the build when a dependency vulnerability is found automatically, it w

In this podcast, QCon Chair Wesley Reisz talks to Julien Viet.  Viet is the project lead for Vert.x and a principal engineer at RedHat having taken over as project lead for Vert.x from Tim Fox in January 2016.  They talk about the newly released Vert.x 3.5.0, and the plans for Vert.x 4.0. Why listen to this podcast: * Vert.x adds RxJava2 support for streams and backpressure. * Vert.x is a polyglot set of APIs, custom aligned for the specific language. * It is unopinionated and can be used with any environments, since it doesn’t enforce a particular framework. * Verticles communicate in-VM or through peer-to-peer networking for distributed applications. * Vert.x 4.0 is on the roadmap for the future.

What can software learn from industries like aerospace, transportation, or even retail during national disasters? This week’s podcast is with Emil Stolarsky and was recorded live after his talk on the subject at Strangeloop 2017. Interesting points from the podcast include several stories from Emil’s research, including the origin of the checklist, how Walmart pushed decision making down to the store level in a national disaster, and where the formalized conversation structure onboard aircraft originated. The podcast mentions several resources you can turn to if you want to learn more and wraps with some of the ways this research is affecting incident response at Shopify. Why listen to this podcast: * Existing industries like aerospace have built a working history of how to resolve issues; it can be applicable to software issues as well. * Crew Resource Management helps teams work together and take ownership of problems that they can solve, instead of a command-and-control mandated s

In this podcast, recorded live at Strange Loop 2017, Wes talks to Charity, cofounder and CEO of honeycomb.io. They discuss the social side of debugging and her Strange Loop talk “Observability for Emerging Infra: What got you Here Won't get you There”. Other topics include advice for testing in production, shadowing and splitting traffic, and sampling and aggregation. Why listen to this podcast: - Statistical sampling allows for collecting more detailed information while storing less data, and can be tuned for different event types. - Testing in production is possible with canaries, shadowing requests, and feature switches - Pulling data out of systems is just noise - it becomes valuable once someone has looked at it and indicates the meaning behind it. - Instrumenting isn’t just about problem detection - it can be used to ask business questions later - You can get 80% of the benefit from 20% of the work in instrumenting the systems.

Nora Jones, a senior software engineer on Netflix’ Chaos Team, talks with Wesley Reisz about what Chaos Engineering means today. She covers what it takes to build a practice, how to establish a strategy, defines cost of impact, and covers key technical considerations when leveraging chaos engineering. Why listen to this podcast: - Chaos engineering is a discipline where you formulate hypotheses, perform experiments, and evaluate the results afterwards. - Injecting a bit of failure over time is going to make your system more resilient in the end. - Start with Tier 2 or non-critical services first, and build up success stories to grow chaos further. - As systems become more and more distributed, there becomes a higher need for chaos engineering. - If you’re running your first experiment, get your service owners in a war room and get them to monitor the results of the test as it is running.

Shubha Nabar is a senior director of data science for Salesforce Einstein. Prior to working for Salesforce, she was a data scientist at LinkedIn and Microsoft. In the podcast she discusses Salesforce Einstein and the problem space that they are trying to solve, explores the differences between enterprise and consumer for machine learning, and then talks about the Optimus Prime Scala library that they use in Salesforce. Why listen to this podcast: * The volume of data, and hardware advances have made it possible to do machine learning to do them a lot faster. * AI is a science of building intelligent software, encompassing many aspects of intelligence that we tend to think of as human. * If you can’t measure something, you can’t fix it. * You have to think about what you can automate, rather than having a human to try and engineer out all those features. * Get feedback on design. Nora Jones, a senior software engineer on Netflix’ Chaos Team, talks with Wesley Reisz about what Chaos E

This week's podcast features Simon Brown well known for his work training software architects. Topics include the differences between a tech lead and an architect, how much documentation is enough and what that looks like in a continuous delivery environment. What you'll learn on this podcast: • As an industry we seem to have lost our knowledge of how to do architecture well in the context of modern agile software teams. • Architecture is about the expensive decisions; things that are costly to change later. • Ideally architects should code in the production code base. If you are not able to do this at least be involved in quality reviews and peer reviews in the production code so you can get feedback on your designs. • It is often said the the code is the only documentation you need but the code can’t tell you everything. You do need to document the things you can’t get from the code such as the architectural drivers, they key quality attributes and so on along with some high level d

This week's podcasts features Yao Yue of Twitter. Yao spent the majority of her career working on caching systems at Twitter. She has since created a performance team that deals with edge performance outliers often exposed by the enormous scale of Twitter. In this podcast, she discusses standing up the performance team, thoughts on instrumenting applications, and interesting performance issues (and strategies for solving them) they’ve seen at Twitter. Why listen to this podcast: * Performance problems can be caused by a few machines running slowly causing cascading failure * Aggregating stats on a minute-by-minute basis can be an effective way of monitoring thousands of servers * Being able to record second-by-second is often too expensive to centrally aggregate, but can be stored locally * Distinguishing between request timeout and connection/network timeouts is important to prevent thundering herds * With larger scale organisations, having dedicated performance teams helps centrali

On the InfoQ Podcast this week, Wes Reisz talks with the Queen of Patterns, Linda Rising. Linda discusses her thoughts on the importance of patterns, she answers questions about what really is a pattern, and how she became involved in working with them. Throughout the podcast she discusses a variety of organizational and personal patterns and finally wraps with patterns to apply when driving change and innovation. Why listen to this podcast: - You have to realise that there’s nothing you can do about other people. The only person you can affect is yourself. - A pattern is not a band-aid that you use once. You use it in a context where you use it in conjunctions with other patterns. - Take baby steps when driving change in an organisation, and seek out a pocket of receptive people to drive it. - Slack is an important part to have in life, so that if something comes along you can absorb it without having to stop doing something else. - Listen, Listen, Listen.

Wesley Reisz talks with Sam Newman about microservices. They explore the current state of the art with regards the architectural style and corresponding tooling and deployment platforms. They then discuss how microservices increase the surface area of where sensitive information can be read or manipulated, but also have the potential to create systems that are more secure. Why listen to this podcast: - Different organisations have different risk appetites for new technology, so what may be appropriate for one organisation may not be appropriate technology choices for another. - If you are deploying micro services then you need to know why you are doing it and what benefits you expect to get from deploying them. - Micro services are defined by their independently deployable units rather than their size. - Using a cryptographic token that is verifiable off line is a common pattern for passing authentication contexts around to different services. - Serverless architectures redeu

Wesley Reisz talks with Jessica Kerr about her focus on developer productivity. Topics include her work at Atomist building Slack Chatbots, an approach to categorizing Yak Shaving (in an effort to prioritize and automate development dependencies), how an innovation culture drives diversity, and, finally, the role of 10x developers in the lifecycle of a company or product. Why listen to this podcast: - There are five kinds of Yak to shave - Atomist uses a Slack chatbot to automate and track commits, builds, push requests etc. - Agile retrospectives are a great way to encourage an innovation culture - Diverse teams flourish in innovation cultures - 10x developers are great for launching products, but teams are needed as products scale up More on this: Quick scan our curated show notes on InfoQ http://bit.ly/2uO60PR You can also subscribe to the InfoQ newsletter to receive weekly updates on the hottest topics from professional software development. bit.ly/24x3IVq Subscribe: www.

Werner Schuster talks to Martin Hadley, data scientist at University of Oxford. They discuss the state of the R language, the rich R ecosystem that covers development (RStudio), notebooks for publication (R Notebooks, RPubs), writing web apps (Shiny), and the pros/cons of the different data frames implementations. Why listen to this podcast: - R is the tool for working with rectangular data - Modern data frame implementations are Tibble and data.table (for large amounts of data) - RMarkdown and R Notebooks allow to explore data and then publish it the results and (interactive) visualization - Use Shinyapps to publish server side R applications - Tidyverse is the place to look for modern R packages More on this: Quick scan our curated show notes on InfoQ http://bit.ly/2twOXWJ You can also subscribe to the InfoQ newsletter to receive weekly updates on the hotest topics from professional software development. bit.ly/24x3IVq Subscribe: www.youtube.com/infoq Like InfoQ on Facebook

In this podcast Charles Humble talks to Sylvan Clebsch, who is the designer of the actor-model language Pony programming and now works at Microsoft Research in Cambridge in the Programming Language Principles group. They talk about the inspirations behind Pony, how the garbage collector avoids stop-the-world pauses, the queuing systems, work scheduler, and formal verification. Why listen to this podcast: * Pony scales from a Raspberry Pi through a 64 core half terabyte machine to a 4096 core SGI beast * An actor has a 256-byte overhead, so creating hundreds of thousands of actors is possible * Actors have unbounded queues to prevent deadlock * Each actor garbage collects its own heap, so global stop-the-world pauses are not needed * Because the type system is data-race free, it’s impossible to have concurrency problems in Pony More on this: Quick scan our curated show notes on InfoQ http://bit.ly/2tZXcKE You can also subscribe to the InfoQ newsletter to receive weekly updates on

Why listen to this podcast: - Kotlin is an officially supported language on Google Android platforms - Kotlin Native and Kotlin JS will allow code reuse between server, client and mobile devices - Type safety means that references can be checked for nullability Great tooling is a driver in what kind of language features are (and aren’t) adopted - Coroutines provide a way of creating maintainable asynchronous systems More on this: Quick scan our curated show notes on InfoQ http://bit.ly/2sHyxqQ You can also subscribe to the InfoQ newsletter to receive weekly updates on the hottest topics from professional software development. bit.ly/24x3IVq Subscribe: www.youtube.com/infoq Like InfoQ on Facebook: bit.ly/2jmlyG8 Follow on Twitter: twitter.com/InfoQ Follow on LinkedIn: www.linkedin.com/company/infoq Want to see extented shownotes?

Wesley Reisz talks to Sid Anand, a data architect at cybersecurity company Agari, about building cloud-native data pipelines. The focus of their discussion is around a solution Agari uses that is built from Amazon Kinesis Streams, serverless functions, and auto scaling groups. Sid Anand is an architect at Agari, and a former technical architect at eBay, Netflix, and LinkedIn. He has 15 years of data infrastructure experience at scale, is a PMC for Apache Airflow, and is also a program committee chair for QCon San Francisco and QCon London. Why listen to this podcast - Real-time data pipeline processing is very latency sensitive - Micro-batching allows much smaller amounts of data to be processed - Use the appropriate data store (or stores) to support the use of the dataIngesting data quickly into a clean database with minimal indexes can be fast - Communicate using a messaging system that supports schema evolution More on this: Quick scan our curated show notes on InfoQ http:/

Wesley Reisz talks to Sachin Kulkarni, Director of Engineering at Facebook, about the engineering challenges for Facebook live, and how it compares to the video upload platform at Facebook. Why listen to this podcast: - Facebook Infrastructure powers the board family of apps including the Facebook app, Messenger and Instagram. It is largely a C++ shop. There is some Java and Python, and the business logic is all done in PHP. The iOS apps are written in Objective C and the Android apps are in Java. - The video infra team at Facebook builds the video infrastructure across the whole company. Projects include a distributed video encoding platform which results in low latency video encoding, video upload and ingest. - Facebook Live does encoding on both the client and the server. The trade-off between encoding on the client side and the server side is mostly around the quality of the video vs. latency and reliability. - Facebook gets around 10x speed-up by encoding data in par

Wesley Reisz talks to Martijn Verburg, co-founder of the London Java Community and CEO of jClarity, about the JCP EC “no” vote on the Java Platform Module System (JPMS), which is due to be shipped as part of Java 9. The talk about what JPMS offers, how it works, what the no vote means and what happens next. Why listen to this podcast: - Jigsaw isn’t dead - The “no” vote was based on the submission being a bit early, and without expert group consensus that it should be submitted - Since the vote started, several amendments have been made which addressed some of the concerns listed by those who voted “no” - Daily calls with the expert group and interested parties will work to resolve the outstanding issues promptly - A resubmission is due within 30 days with a future vote expected to go through More on this: Quick scan our curated show notes on InfoQ http://bit.ly/2q20esc You can also subscribe to the InfoQ newsletter to receive weekly updates on the hottest topics from professiona

Wesley Reisz talks to Daniel Bryant on moving from monoliths to micro-services, covering bounded contexts, when to break up micro-services, event storming, practices like observability and tracing, and more. Why listen to this podcast: - Migrating a monolith to micro-services is best done by breaking off a valuable but not critical part first. - Designing a greenfield application as micro-services requires a strong understanding of the domain. - When a request enters the system, it needs to be tagged with a correlation id that flows down to all fan-out service requests. - Observability and metrics are essential parts to include when moving micro-services to production. - A service mesh allows you to scale services and permit binary transports without losing observability.

Rossen Stoyanchev talks to Wesley Reisz about blocking and non-blocking architectures, upcoming changes in Spring including Spring WebFlux, the reactive web stack in Spring framework 5, due this summer. He also discusses the differences between rxJava and Reactor. Why listen to this podcast: - Spring Framework 5 is due to be released June 25 2017 - Spring Web Flux provides a web programming model designed for asynchronous APIs - Back-pressure is important in a server environment; less so within a UI environment - It’s possible to use a Spring Web Flux client within a Spring MVC applciation - Managing sets of thread pools is more complicated than having a scalable asynchronous system More on this: Quick scan our curated show notes on InfoQ http://bit.ly/2pPgq0G You can subscribe to the InfoQ newsletter to receive weekly updates on the hottest topics from professional software development. bit.ly/24x3IVq Subscribe: www.youtube.com/infoq Like InfoQ on Facebook: bit.ly/2jmlyG8 F

Why listen to this podcast: - Using a compiler to catch errors at compile time instead of at runtime means much easier refactoring of code. - Incrementally replacing small parts of an existing JavaScript application with Elm is a safer strategy than trying to write an entirely new application in Elm - Elm packages are semantically versioned and gated by the publishing process, so minor versions cannot remove functionality without bumping the major version. - The UI in an Elm application results in messages that transform the immutable state of the application; this allows a debugger to view the state transitions and the messages that triggered them, including record and replay of those messages. - Elm has been benchmarked as being faster than Angular and React whilst being smaller code, which is attributed to the immutable state and pure functional elements.

Eric Horesnyi, CEO @streamdata.io, talks to Charles Humble about how hedge funds are applying deep learning as an alternative to the raw speed favoured by HFT to try and curve the market. Why listen to this podcast: - Streamdata.io was originally built for banks and brokers, but more recently hedge funds have begun using the service. - Whilst Hedge Funds like Renaissance Technologies have been using mathematical approaches for some time deep learning is now being applied to markets. Common techniques such as gradient descent and back propagation apply equally well to market analysis. - The data sources used are very broad. As well as market data the network might be using, sentiment analysis from social networks, social trading data, as well as more unusual data such as retail data, and IoT sensors from farms and factories. - By way of contrast High Frequency Trading focusses on latency. From an infrastructure stand-point you can play with propagation time, Serilization (the th

Wesley Reisz talks to Slava Oks, who has worked at Microsoft for over 20 years on flagship products, including SQL Server. He also led the kernel team who worked on the Midori operating system. More recently, he has worked on bringing SQL Server to Linux. Why listen to this podcast: - Microsoft SQL Server runs on Linux through a containerised approach called Drawbridge - Drawbridge implements a Linux loader and a minimal set of ABI calls to allow an in-process NT user mode kernel to run - SQL Server runs on top of a SQL platform layer (called SQL OS) that could be ported to run on Drawbridge - SQL Server had supportability commands added to allow the state of the system to be measured with SQL calls - A number of efficiency gains were applied to both the Drawbridge components and the SQL Server code to bring performance to within 20% of the equivalent process running on Windows Notes and links can be found on: http://bit.ly/2kVfatX Drawbridge ABIs Security LibOS Linux SQL OS S

Jonas Bonér, CTO of LightBend and creator Akka, discusses using Akka when developing distributed systems. He talks about the Actor Model, and how every Microservice needs to be viewed as a system to be successful. Why listen to this podcast: - Akka is JVM-based framework design for developing distributed systems leveraging the Actor Model - an approach for writing concurrent systems that treat actors as universal primitives and the most successful model with abstraction has been streaming - Circuit breakers in Akka are a backup and retry policy; they protect you by capturing failure data and allow you to roll back - Every Microservice needs to be viewed as a system, it needs to have multiple parts that run on different machines in order to function and be fully resilient - thus is a Microsystem - Two different trends have emerged when it comes to hardware and environments: one is the trend toward Multi-core, the is a movement toward virtualized environments and the cloud - Sag

Peter Bourgon discusses his work at Weaveworks, discovering and imlemeting CRDTs for time-stamped events at Soundcloud, Microservices in Go with Go Kit and the state of package management in Go. Why listen to this podcast: - We’ve hit the limits of Moore’s law so when we want to scale we have to think about how we do communication across unreliable links between unreliable machines. - In an AP algorithm like Gossip you still make forward progress in case of a failure. In Paxos you stop and return failures. - CRDTs give us a rigours set of rules to accommodate failures for maps, sets etc. in communication that result in am eventually consistent system. - Go is optimised to readers/maintainers vs. making the programmers’ life easier. Go is closer to C than Java in that it allows you to layout memory very precisely, allowing you to, for example, optimise cache lines in your CPU. - Bourgon started a project called Go Kit, which is designed for building microservices in Go. It takes

In this week’s podcast Wes Reisz talks to Neha Batra, a software engineer at Pivotal Labs. Neha spoke about pair programming in her recent QCon San Francisco 2016 presentation, and has taken time to discuss techniques to get started with the practice as well as tips for implementing it on your team. Neha also touches on vulnerability based trust and how it can help effectively build a trusting team environment. Why listen to this podcast: - If you successfully start with pair programming, other tenants of XP are pulled along with you - Ways to get creative with remote pairing to make it work - The daily retro - Overcoming hesitance with managers when trying to implement pair programming full time - Vulnerability based trust building Notes and links can be found on: http://bit.ly/2i2a0sJ How has Pair Programming Evolved Over the Years? 6m:17s - A lot of the fundamentals are the same, but with XP we take it to the extreme to be able to do it eight hours a day. 6m:24s - To pair

In this week’s podcast, Robert Blumen talks to Oliver Gould at QCon San Francsico 2016. Oliver is the CTO of Buoyant where he leads open source development efforts. Prior to Buoyant he was a Staff Infrastructure Engineer at Twitter where he was technical lead on Observability, Traffic, Configuration and Co-ordination teams. Why listen to this podcast: - Stratification allows applications to own their logic while libraries take care of the different mechanisms, such as service discovery and load balancing - Cascading failures can’t be tested or protected against, so having a fast time to recovery is important - Having developers own their services with on-call mechanisms improves the reliability of the service; it’s best to optimise automatic restarts so problems can be addressed during normal working hours - Post mortem analysis of failures are important to improve run books or checklists and to share learning between teams - Incremental roll out of features with feature flags o

In this week’s podcast, Thomas Betts talks with Chris Richardson, a developer, architect, Java Champion and author of POJOs in Action. Before his workshop on Microservices w/ Spring Boot and Docker at QCon San Francisco 2016, Richardson took time to discuss his ideas on how to use DDD and CQRS concepts as a guide for implementing a robust microservices architecture. Why listen to this podcast: - "Microservice architecture" is a better term than "microservices". The latter suggests that a single microservice is somehow interesting - The concepts discussed in Domain-Driven Design are an excellent guide for how to implement a microservices architecture - Bounded Contexts correspond well to individual microservices - Event sourcing and CQRS provide patterns for how to implement loosely coupled services - When converting a monolith to microservices, avoid a big bang rewrite, in favor of an iterative approach Notes and links can be found on: http://bit.ly/2hZ8TM1 11m:51s - Microse

In this week’s podcast, QCon chair Wesley Reisz talks to Keith Adams, chief architect at Slack. Prior he was an engineer at Facebook where he worked on the search type live backend, and is well-known for the HipHop VM [hhvm.com]. Adams presented How Slack Works at QCon SanFrancisco 2016. Why listen to this podcast: - Group messaging succeeds when it feels like a place for members to gather, rather than just a tool - Having opt-in group membership scales better than having to define a group on the fly, like a mailing list instead of individually adding people to a mail - Choosing availability over consistency is sometimes the right choice for particular use cases - Consistency can be recovered after the fact with custom conflict resolution tools - Latency is important and can be solved by having proxies or edge applications closer to the user Notes and links can be found on: http://bit.ly/keith-adams 3m:30s Voice and video interactions are impacted by latency; the same is true

In this week’s podcast, Thomas Betts talks with Haley Tucker, a Senior Software Engineer on the Playback Features team at Netflix. While at QCon San Francisco 2016, Tucker told some production war stories about trying to deliver content to 65 million members. Why listen to this podcast: - Distributed systems fail regularly, often due to unexpected reasons - Data canaries can identify invalid metadata before it can enter and corrupt the production environment - ChAP, the Chaos Automation Platform, can test failure conditions alongside the success conditions - Fallbacks are an important component of system stability, but the fallbacks must be fast and light to not cause secondary failures - Distributed systems are fundamentally social systems, and require a blameless culture to be successful Notes and links can be found on: http://bit.ly/2hqzQ6K 2m:05s - The Video Metadata Service aggregates several sources into a consistent API consumed by other Netflix services. 2m:43s - Seve

In this week's podcast, QCon chair Wesley Reisz talks to Kolton Andrus. Andrus is the founder of Gremlin Inc. He was a Chaos Engineer at Netflix, focused on the resilience of the Edge services. He designed and built FIT: Netflix’s failure injection service. Prior, he improved the performance and reliability of the Amazon Retail website. Why listen to this podcast: - Gremlin, Kolton Andrus' new start-up, is focused on providing failure testing as a service. Version 1, currently in closed beta, is focused on infrastructure failures. - Lineage-driven Fault Injection (LDFI) allowed Netflix to dramatically reduce the number of tests they needed to run in order to explore a problem space. - You generally want to run failure tests in production, but you can't start there. Start in developemnt and build up. - Having failure testing at an application level, as Netflix does, so you can have request level fault injection for a specific user or a specific device. - Being able to trace infrastr

As InfoQ previously reported in March 2016, Dropbox announced that they had migrated away from Amazon Web Services (AWS). In this week's podcast Robert Bluman talks to Preslav Le. Preslav has been a software engineer at Dropbox for the past three years, contributing to various aspects of Dropbox’s infrastructure including traffic, performance and storage. He was part of the core oncall and storage oncall rotations, dealing with high emergency real world issues, from bad code pushes to complete datacenter outages. Why listen to this podcast: - Dropbox migrated away from Amazon S3 to their own data centres to allow them to optimise for their specific use case. - They are experimenting with Shingled Magnetic Recording (SMR) drives for primary storage to increase storage density. All writes go to an SSD cache and then get pushed asynchronously to the SMR disk. - Their average block size is 1.6MB with a maximum block size of 4MB. Knowing this allows the team to tune their storage syst

In this week's podcast QCon chair Wesley Reisz talks to Randy Shoup. Shoup is the vice president of engineering at Stitch Fix. Prior to Stitch Fix, he worked for Google as the director of engineering and cloud computing, CTO and co-founder of Shopilly, and chief engineer at Ebay. Why listen to this podcast: - Stitch Fix's business is a combination of art and science. Humans are much better with the machines, and the machines are much better with the humans. - Stitch Fix has 60 engineers, with 80 data scientists and algorithm developers. This ratio of data science to engineering is unique. - With Ruby-on-Rails on top of Postgres, the company maintains about 30 different applications on the same stack. - The practice of Test Driven Development makes Continuous Delivery work, and the practice of having the same people build the code as those who operate the code makes both of these things much more powerful. - Microservices gives feature velocity, the ability for individual teams t

In this week's podcast, QCon chair Wesley Reisz talks to Tal Weiss, CEO of OverOps, recently re-branded from Takipi. The conversation covers how the OverOps product works, explores the difference between instrumentation and observability, discusses bytecode manipulation approaches and common errors in Java based applications.

Summary: In this week's podcast QCon chair Wesley Reisz talks to Mads Torgersen who leads the C# language design process at Microsoft, where he has been involved in five versions of C#, and also contributed to TypeScript, Visual Basic, Roslyn and LINQ. Before he joined Microsoft a decade ago, he worked as a university professor in Aarhus, Denmark, doing research into programming language design and contributing to Java generics. Why listen to this podcast • The overall theme for C# 7 will be features that make it easier to work with data, including language level support for tuples. Roslyn, the compiler and API, allows a much more agile evolution of the language. • The Omnisharp initiative aims to facilitate easier editing of C# code in other editors, including VS Code. • IoT and Artificial Intelligence are emerging as key disruptive trends. • The release may also include pattern matching for type switching. • C# 7 is the first new release of the language to be completely built in the

Summary: For our inaugural podcast QCon chair Wesley Reisz talks to Adrian Cockcroft, who works for Battery Ventures where he advises the firm and its portfolio companies about technology issues and also assists with deal sourcing and due diligence. Why listen to this podcast • Over the last year a large number of frameworks and libraries for building microservices have emerged and we're seeing a lot of rapid change. • The stack you choose will often be based on the main language you use, so for example Netflix’s stack is language agnostic but the tooling is very Java-centric. • Architectural choices can have a profound impact on success, so some-thing as simple as an overly long timeout with retries can cause your system to suffer from a congestion collapse problem. Have a large timeout at the edge, and progressively smaller and smaller timeouts as you get deeper into the system. • Start with a monolith and move to a distributed architecture when you need to because of team size or t
