Polly can improve the customers' user experience in mobile and web applications. But do you know you can also use Polly in microservices communication? In this talk, I will show you a step-by-step process of building two simple .NET 6 Services and working with the Polly library to ensure we can handle any transient faults that may occur when one service calls the other. I will start with different types of exposing your microservices like direct, facade, and API gateway. Then what is Retry Policy? What is Circuit Breaker Policy? What is Infrastructure-based resiliency? And how to implement them in DotNET apps.
