In a distributed system, failure isn't just possible — it's inevitable. The question isn't whether your services will fail, but how gracefully they'll handle failure when it happens.
Embracing Failure
Resilient microservices are designed with failure in mind. They expect network partitions, service outages, and cascading failures, and they have strategies to handle each scenario.
Resilience patterns:
- →Circuit breakers to prevent cascade failures
- →Retry with exponential backoff
- →Bulkheads to isolate failures
- →Timeouts to prevent resource exhaustion
“A system is only as strong as its weakest link — unless you design it so that weak links can break without bringing down the whole chain.”
