Resilience and Fault Tolerance with Polly

Polly is a lightweight, expressive, and powerful .NET resilience library that handles transient failures through retries, circuit breakers, timeouts, bulkhead isolation, and fallbacks. Modern microservices must tolerate network delays, service degradation, and cascading failures—and Polly gives you the tools to do it elegantly. In .NET 8+, the new Resilience Pipeline offers native integration and improved observability. This series teaches you how to implement each pattern, combine them strategically, and deploy them safely in production systems handling real-world traffic.
