Polly is a .NET resilience library for retries, circuit breakers, timeouts, and bulkheads.
Integrate Polly with HttpClientFactory to handle transient faults when calling external services.
Patterns: Retry with backoff, circuit breaker, fallback, timeout.
Architecture impact: Resilience policies protect your .NET Core services from cascading failures in distributed systems.
