The Microservices Problem No One Warned Us About (And How You Can Avoid It) (bobkonf2025)

Tired of firefighting when a downstream service throws a curveball? We were too, so we figured out a way to build microservices that expect the unexpected. In this talk, I’ll share our journey from fragile systems to an architecture where resilience is the norm, not the exception. Soon after introducing microservices we were so overwhelmed by constant outages and endless alerts that we couldn’t even stop to figure out what was going wrong. In this talk, I’ll share how we rediscovered the Saga pattern during that chaos and how it transformed our fragile system into a resilient one. By exploring the failure modes and incomplete implementations we encountered, you’ll gain a deeper understanding of the pattern and how to apply it effectively to build more reliable systems. This talk isn’t just a war story; it’s a blueprint for resilience. You’ll walk away with a crucial pattern that you can immediately apply to your systems, turning potential disasters into manageable events, and achieve a 99.999% uptime.
