The circuit breaker pattern can be used in many different scenarios and it is very effective in systems where there are multiple dependent services that collectively form to get a higher level of service. Implementing a circuit breaker needs planning in the following areas:
- Implementation: Implementing the circuit breaker with a framework such as Spring Cloud is recommended since the implementation can be complex and should not add any additional latency to the requests. A few advantages include having common behavior across many different implementations and features such as logging, which can help with understanding the health of the application, and proper exception handling can be enabled uniformly.
