of the invocation of the fault service, thus avoiding the spread of the fault in the distributed system.Netflix HystrixThe hystrix is used in spring cloud to realize the function of the circuit breaker. Hystrix is one of Netflix's open source MicroServices framework packages designed to provide greater fault tolerance for latency and failures by controlling the

In a microservices architecture, the service is split into services based on the business, and services and services can be called each other (RPC), which can be invoked with the rest Template + ribbon and feign in spring cloud. To ensure their high availability, a single service is typically deployed in a cluster. Due to network reasons or their own reasons, the service does not guarantee that 100% is available, if a single service problem, call the

Brief introductionSpring Cloud provides a hystrix fault-tolerant library to temporarily invoke an alternate method when the service is unavailable, and a downgrade strategy is implemented for the method that configures the circuit breaker. This article creates a product microservices, registers to the Eureka Service registry, and then we use the Web Client Access

1. Hystrix Circuit Breaker Hystrix is an open-source repository for latency and fault tolerance in distributed systems where many dependencies inevitably fail to be invoked.such as timeouts, anomalies, etc., Hystrix can ensure that in the case of a dependency problem, will not cause the overall service failure, avoid cascading failures, to improve the sub-The elasticity of the cloth-type system;
