Observability in an Asynchronous World

Imagine that you’ve designed and built an event-driven system. It’s working brilliantly – until one night, at 3am, your pager goes off. You’re not sure what broke, and you don’t have the tools to quickly diagnose the issue. Your users are frustrated, messages are flying between systems, and you have no way to understand who is talking to who or what is causing the outage.

How do you get to a place where you can confidently respond to that page, and quickly get your system back online for your users? That’s what you’ll learn in this talk, as Eastham takes you on a journey into the world of observability in event-driven systems. From understanding cause and effect in your architecture to practical implementation details and, most importantly, how to let the needs of your users drive your observability strategy.
