Building Resilient Systems — Circuit Breakers & Retries

Building Resilient Systems: Circuit Breakers & Retry Patterns

How to build systems that fail gracefully and recover automatically.

In distributed systems, failures are inevitable. The question isn't whether things will fail, but how your system responds when they do.

The Circuit Breaker Pattern

Inspired by electrical circuit breakers, this pattern prevents cascading failures by stopping requests to failing services.

Exponential backoff with jitter, retry budgets, and deadline-aware retries prevent retry storms from making things worse.

Isolating resources so that a failure in one area doesn't bring down the entire system.
