Here is an uncomfortable truth about observability: you only find out your dashboards are wrong, your alerts are silent, and your traces are broken during an incident. The one moment you most need visibility is the moment you discover you never had it. Chaos engineering flips that script. Instead of waiting for production to break and hoping your telemetry holds up, you deliberately inject controlled failures and verify that your metrics, logs, and traces actually captured what happened.

In today’s distributed systems landscape, services are interconnected through complex networks of API calls, database queries, and external service dependencies. When one service experiences issues, it can create a cascading failure that brings down entire systems. This is where the Circuit Breaker pattern becomes invaluable—acting as a protective mechanism that prevents failing services from overwhelming the entire system. The Circuit Breaker pattern, inspired by electrical circuit breakers, monitors service calls and “trips” when failures exceed a certain threshold, temporarily blocking requests to give the failing service time to recover.
