Microservices Circuit-Breaker Pattern Implementation ... circuit breaker pattern is one of the ways to handle the lack of availability of a service: instead of queuing requests and choking the caller, it fails fast and returns immediately. There are two ways to implement the circuit breaker, the black-box way and the white-box way. Istio, as a proxy management tool, uses the black-box way.
