In a distributed architecture, the role of the circuit breaker pattern is similar, when a service unit fails (similar to a short-circuit with electrical appliances), through the fault monitoring of the circuit breaker (similar to a fuse fuse), to the caller returned an error response, rather than a long wait. This does not cause the thread to fail to be released for a long time because of the invocation of the fault service, thus avoiding the spread of the fault in the distributed system.Netflix

Spring Cloud Config is a new project created by the spring Cloud team to provide centralized external configuration support for infrastructure and microservices applications in distributed systems, which are divided into two parts: server and client. The server, also known as the Distributed Configuration Center, is a standalone
