{{Short description|Software development pattern}}
'''The Circuit breaker'''Breaker is a [[Design pattern (computer science)|design pattern]] commonly used in [[software development]] to improve system resilience and fault tolerance. Circuit breaker pattern can prevent [[cascading failure]]s particularly in [[Distributed computing|distributed systems]].<ref>{{Cite book |title=Machine Learning in Microservices Productionizing Microservices Architecture for Machine Learning Solutions |publisher=Packt Publishing |year=2023 |isbn=9781804612149}}</ref> In distributed systems, the Circuit Breaker pattern can be used to monitor service health and can detect failures dynamically. Unlike [[Timeout (computing)|timeout]]-based methods, which can lead to delayed error responses or the premature failure of healthy requests, the Circuit Breaker pattern can proactively identify unresponsive services and can prevent repeated attempts. This approach can enhance the user experience. <ref name=":1">{{Cite book |last=Richards |first=Mark |title=Microservices AntiPatterns and Pitfalls |publisher=O'Reilly}}</ref>
The circuit breaker pattern can be used in conjunction with other patterns, such as retry, fallback, and timeout, to enhance fault tolerance in systems. <ref>{{Cite book |title=Kubernetes Native Microservices with Quarkus and MicroProfile |publisher=Manning |year=2022 |isbn=9781638357155}}</ref>
