Failures happen when calling remote services and handling these failures has never been easy. That was the case until the Polly project came along. Polly is a resilience framework for .Net. In this course, Fault Tolerant Web Service Requests with Polly, you will learn how to make your applications resilient to a wide range of failures and outages in remote services. First, you will learn to use the simple and very powerful retry policies. Next, you will see how to use some of the other policies offered by Polly like caching and fallback. You will also learn how to reuse policies across multiple applications and how to unit test everything. Finally, you will explore how to use the more advanced features of Polly – the circuit breaker and bulkhead isolation. By the end of the course, you will be able to use all the features of Polly to build robust applications that can tolerate short and long term outages in remote services.
