The Infoq Podcast

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.

Domain storytelling is a technique for understanding a business domain by relying on people’s natural ability to learn a new language by listening to other people speaking that language. In this episode of the podcast, Stefan Hofer and Henning Schwentner cover when to use domain storytelling, what is involved in the pictographic language, and how to have productive storytelling sessions. They go into far greater detail in their new book, Domain Storytelling.

In their upcoming book, Software Architecture: The Hard Parts, Neal Ford and Mark Richards explain that every architectural decision involves trade-offs, and provide guidance on how to evaluate those trade-offs. In this episode of the InfoQ Podcast, co-host Thomas Betts spoke with Neal and Mark about the role of a software architect and the skills necessary to be successful. One of the hardest parts is recognizing that there are no right or wrong answers, or easy decisions, and this can be especially challenging for those who come from a programming background.

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.

On this episode of the podcast, Fran Mendez, founder of the AsyncAPI Initiative spoke with co-host Thomas Betts. AsyncAPI is a specification and growing set of tools to help developers define asynchronous APIs, and build and maintain event-driven architectures. AsyncAPI hopes to provide features and benefits to those of OpenAPI (fka Swagger) for RESTful APIs. The specification and all tooling are community-driven and fully open source.

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 cloud native architecture.

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.
