Amazon  C ircuit Breaker :  When the number of consecutive failures crosses a threshold, the circuit breaker trips, and for the duration of a timeout period all attempts to invoke the remote service will fail immediately. After the timeout expires the circuit breaker allows a limited number of test requests to pass through. If those requests succeed the circuit breaker resumes normal operation. Otherwise, if there is a failure the timeout period begins again. @EnableCircuitBreaker class UserRegistrationConfiguration { Amazon <a target="_blank" href="https://www.amazon.in/b?_encoding=UTF8&tag=bayareddy-21&linkCode=ur2&linkId=15ff6c4a39b041249058632ec17c92c8&camp=3638&creative=24630&node=1389375031">TV</a>
