What’s up, fellow geeks? Think of the time when you are treated at a busy pizza place. The pizza oven broke down, and with new orders coming in, the entire kitchen is at a standstill. If we take that oven as a flaky, unreliable third-party API, there you go—microservices disaster! With retries and circuit breakers at your disposal, you can ensure your system keeps sizzling instead of crashing down.
In this guide, I will share these patterns assuming we are doing some pair programming at a whiteboard. We will look at some code (Hystrix and Resilience4J), tell war stories, revel in my failures (hint: wild retries), and have a good time. Let’s get down to it, shall we?
