Learn Microservice with Spring Cloud : Lesson 31 - Circuit Breaker Pattern using Netflix Hystrix

In this video, we will learn how to use Hystrix to solve the problem that comes with a distributed microservice architecture, like in the project that we have. And these problems are fault and latency tolerance.

Looking at our business API service, it is fetching data from both catalog and inventory service. But what if those services failed, or the response is delayed? It will affect the overall integrity of the application or even worst it might bring the whole system down.

And that is where Hystrix comes in, it wraps the call to remote services and handles the exception or return a default or computed value.
