Resilience Patterns Build systems that survive partial failures and degrade gracefully. Core Patterns Retry with Exponential Backoff Circuit Breaker Timeout Bulkhead (Resource Isolation) Fallback Composition Chain patterns for defense in depth: Queue-Based Load Leveling Health Check Patterns Failure Mode Analysis | Failure Mode | Pattern | Recovery | |-------------|---------|----------| | Transient network error | Retry with backoff | Automatic | | Service down | Circuit breaker | Automatic after recovery | | Service overloaded | Bulkhead + rate limit | Shed load | | Slow response | Timeout |…
