Jagadeesh Devaraj and Marcel Punselie, ING
"It worked on my machine." Famous last words before prod goes up in smoke. This talk explores how we built a smart "drift radar system" that catches misconfigurations, rogue YAMLs, infra drift, sneaky app bugs before they hit production. Learn how we used control loops, runtime policy enforcement, and CI/CD sensors to stop reliability failures in their tracks. Expect real war stories, platform-agnostic tactics, and practical takeaways for developers, SREs, and platform engineers who want to make resilience effortless and scalable.
