Non-functional requirements like performance, scalability, and resiliency are often treated as an afterthought, leading to late-stage firefighting and costly rework. This session shows how to build them in from the start through continuous validation. You’ll learn how to use Azure’s testing and monitoring ecosystem to proactively surface issues, including automated load tests, chaos experiments, telemetry-driven insights, and failure mode analysis. With practical demos and pipeline examples, you’ll see how to detect weak spots early, validate system behavior under stress, and prevent small issues from becoming production incidents. If you want to shift from reactive fixes to engineering reliability and performance into your software every day, this talk gives you the mindset and toolkit to do it.
