Configure your circuit breaker parameters using the input fields above. Use the simulation buttons to test different scenarios and observe how the circuit breaker responds to failures and recoveries. The tool provides real-time feedback and generates production-ready code.
Understanding Circuit Breaker Patterns
Circuit breakers prevent cascading failures in distributed systems by monitoring service calls and "opening" when failure rates exceed thresholds. This tool helps you understand and implement this critical resilience pattern with visual feedback and metrics.
Key Configuration Parameters
- Failure Threshold: Number of consecutive failures before opening the circuit
- Timeout: Maximum time to wait for a service response
- Recovery Timeout: Time to wait before attempting to close the circuit
- Success Threshold: Number of successful calls needed to close the circuit from half-open state
Circuit States Explained
- CLOSED (🟢): Normal operation - requests are passed through
- OPEN (🔴): Failures detected - requests are rejected immediately
- HALF-OPEN (🟡): Testing phase - limited requests allowed to test service recovery
Benefits for Cloud Applications
Circuit breakers are essential for cloud-native applications hosted on platforms like Kloudbean. They improve system resilience, prevent resource exhaustion, and provide better user experience during service outages. The generated code is production-ready and follows industry best practices.
Frequently Asked Questions
Q. When should I use a circuit breaker?
Use circuit breakers when calling external services, databases, or any dependency that might fail. They're especially important in microservices architectures.
Q. How do I choose the right failure threshold?
Start with 5-10 failures. Adjust based on your service's normal error rate and acceptable risk tolerance. Lower thresholds provide faster failure detection but may be too sensitive.
Q. What's the difference between timeout and recovery timeout?
Timeout is how long to wait for a single request. Recovery timeout is how long to wait before testing if the failed service has recovered.
Q. Can I use this pattern with databases?
Yes, circuit breakers work well with database connections, especially in high-traffic applications where database failures could overwhelm connection pools.
