Test-driven development (TDD) is a process that ensures quality in the applications we develop while guarding against feature creep/skew. But as our applications have become increasingly complex, traditional testing methods are not enough. Traditional testing only evaluates what we know, but complex systems often fail due to unknowns—the things that are almost impossible to test because we are unaware of them. Chaos Engineering is the exception that allows us to test for what we don’t know.

Matt Stratton, host of the Arrested DevOps podcast, will host Jeff Smith, Director of Production Operations at Centro and author of the book "Operations Anti-patterns, DevOps Solutions" for an engaging conversation about building reliable teams using DevOps principles.

Long before Chaos Engineering was even a phrase, Jesse Robbins was Amazon.com's "Master of Disaster" using intentional failure to help the company become more reliable. Kolton Andrus (CEO at Gremlin), sits down with Jesse to learn more about his early work with GameDays, the evolution of reliability, and where the future of SRE lies.

When we talk about reliable systems, we talk a lot about human error. Human error in an incident or a bug report is often treated with a bit of a facepalm reaction. The term masks a lot of scenarios from accidents to exhaustion to everything in between. However, human error helps us understand where our processes failed and how we can prevent the same error from happening again. In short, we need to think in terms of a framework of guidelines and guardrails. In this short talk, let’s discuss how guidelines like runbooks and guardrails like automation can help us address the fact that everyone will, at some point, make mistakes.

Delivering software quickly and securely is important for every organization, but it's even more important at the US Department of Defence (DoD) where reliability directly impacts national security. Nicolas Chaillan (Chief Software Officer, US Air Force) will discuss the DoD Enterprise DevSecOps Initiative—an initiative he leads along with the DOD’s Chief Information Officer that brings automated software tools, services and standards to DoD programs. He'll also share about Platform One, the Air Force's DoD-wide DevSecOps Enterprise Level Service that provides managed IT services capabilities, on-boarding, support, and baked-in zero trust security. This insight from operating at the most rigorous level will help you level up your own organization.
