Most technology leaders are aware of resilience issues but fail to act, despite outages costing millions of dollars.
True resilience requires a multi-layered approach, considering infrastructure, architecture choices like microservices, and application-level communication patterns.
The Polly library provides a fluent, thread-safe way to implement resilience strategies, avoiding manual and error-prone retry logic.
Configure the retry strategy to handle transient failures with exponential backoff and jitter to avoid creating traffic spikes.
Use the circuit breaker pattern to temporarily stop sending requests to a failing service, giving it time to recover.
Control the number of concurrent requests sent to a downstream service using Polly's rate limiter to prevent overloads.
Use Polly's extension methods to add resilience handlers directly to the HttpClient pipeline, separating resilience configuration from business logic.
Intentionally inject failures, latency, and unexpected outcomes into your system using chaos engineering to test if your resilience strategies work as expected.
The Microsoft.Extensions.Http.Resilience package provides a pre-configured, standard resilience pipeline for HttpClient, simplifying setup and promoting best practices.
