🔌 The Circuit Breaker Pattern: Stopping Cascading Failures in Software Systems

Explore how the circuit breaker pattern, borrowed from electrical engineering, protects distributed systems by failing fast instead of letting one broken service take down everything that depends on it.

This simulator demonstrates how a circuit breaker moves between Closed, Open, and Half-Open states as request successes and failures accumulate against a configurable threshold.

🔬 What It Demonstrates

This simulator demonstrates how a circuit breaker moves between Closed, Open, and Half-Open states as request successes and failures accumulate against a configurable threshold.

🎮 How to Use

Trigger successful or failing requests and watch the failure counter, state indicator, and timeout clock respond, then observe how Half-Open trial requests decide whether the breaker resets or reopens.

💡 Did You Know?

Netflix's Hystrix, one of the libraries that popularized this pattern, is now in maintenance mode, but its core ideas live on in widely used successors like resilience4j.
