Microservice resilience - Circuit Breaker using polly in .Net Core

Описание: In this video, I demonstrate how to implement microservice resilience using the Circuit Breaker pattern in an ASP.Net Core API application using Polly.

In a microservices environment, usually, multiple services talk to each other either. Some cases through HTTP calls, whereas in other cases using an event bus or queues. Circuit Breaker is an important pattern which helps to make microservices more resilient in these communication patterns.

When services communicate with each other through HTTP calls, there is always a possibility of failure. One service might fail or HTTP connection might break due to network error. In these scenarios creating a resilient service is extremely important. And the circuit breaker is a pattern that helps us to do that.

Reactive communication through Queue and Event bus also might fail, buts its extremely rare compared to the HTTP call.
