API GATEWAY
CIRCUIT BREAKER
Protect your API infrastructure from cascading failures with intelligent circuit breaker patterns. Implement fault tolerance, failure isolation, and graceful degradation for resilient API gateway proxies.
CIRCUIT BREAKER STATES
✓
CLOSED
Normal operation. All requests flow through to the downstream service. The circuit monitors for failures and transitions to OPEN when failure threshold is exceeded.
- Requests processed normally
- Failure count tracking
- Threshold monitoring active
✗
OPEN
Circuit tripped. Requests fail fast without reaching downstream service. After timeout period, circuit transitions to HALF-OPEN to test recovery.
- Fast failure responses
- Timeout period counting
- No downstream calls made
↻
HALF-OPEN
Limited trial state. A small number of test requests are allowed through. If successful, circuit returns to CLOSED; if failed, returns to OPEN.
- Limited test requests
- Success/failure monitoring
- State transition decision
