Use Cases of Circuit Breaker Pattern
- Service Communication: When microservices are communicating with one over the network through the pattern of the Circuit breaker, the document helps to deal with the network failures and with unavailability of service or with slow responses. That, in doing so, it avoids collateral damage of failures by serving as a barrier between a final service and providing alternative options when failure occurs.
- Third-Party Integrations: That is, the microservices are the APIs or services which may be external or from other parties. This Circuit Breaker pattern can be included as a contingency to mitigate against failures in the integrations, enabling the whole system to stay functional even when the external parties are affected by unforeseen issues.
- Asynchronous Processing: Microservices may encompass some duties – e.g., queuing or event processing – that are executed in an asynchronous manner. In this situation, that means Circuit Breaker pattern can be used to tolerate faults in message brokers or event queues, making it possible to continue processing messages even when transient failure occurs.
- Load Balancing: Service instances could be split by circuit breakers together with load balancers in the same time to carry incoming traffic to various instance of that service. Should a service failure occur, the circuit breakers redirect traffic from the failing instance to a healthy instance, meaning that requests are still processed in case of a further failures.
What is Circuit Breaker Pattern in Microservices?
The Circuit Breaker pattern in microservices acts as a safeguard against service failures by monitoring interactions, setting thresholds, and temporarily halting/Stoping traffic to failing services. It helps prevent cascading failures and maintains system stability, ensuring reliable performance in distributed architectures.
