automatically has the function of registry, load Balancing, failover. hystrix There are often multiple service layer calls in the MicroServices architecture, and the failure of the underlying service can lead to cascading failures, which in turn will result in the entire system being unavailable. This phenomenon is called the service avalanche effect. The service avalanche effect is a process in which the service consumer is not available and

business split into a lot of sub-business, and then for each sub-business cluster deployment, so that each sub-business if the problem, the entire system will not be affected. Excerpt from: What is the difference between a distributed and a cluster? Distributed concept reference: Features and design concepts of distributed systems In addition, there is a concept similar to the distribution, that is, microservices.

First, IntroductionThe hystrix provides almost real-time monitoring. When executed, Hystrixcommand and Hystrixobserv-ablecommand generate execution results and run metrics, such as the number of requests executed per second, number of successes, and so on, which are useful for analyzing the state of the application system.Using the Hystrix module hystrix-metrics-event-stream, these monitored metrics information can be exposed to the external system in a Text/event-stream format.
