Cloud bus, when we change the configuration file submission to the repository, it automatically triggers the refresh of the corresponding instance, with the following workflow:Service GatewayIn MicroServices architecture mode, the number of instances of back-end services is generally dynamic, and it is difficult for clients to discover the access address information of dynamically changing service instances. Therefore, in order to simplify the invocation logic of the front end in a microservice

This is used for changes in broadcast status (such as configuration changes) or other message directives.One of the core ideas of spring Cloud Bus is to extend the spring boot application through a distributed launcher, or to e

, the calls between them use the RPC (remote Service invocation) registry, Eureka-server, since there are service providers and service consumers, and they are all running on different hosts, then how to let service consumers discover, And the service provider is invoked according to the corresponding protocol, which introduces the concept of the registry. If the reader has Dubbo experience, it is easy to think of the zookeeper cluster, they provide a similar function.Of course, its deployment i

the cluster is only one node surviving, can also provide a normal discovery service. Even if all service registration nodes are hung up, the service invocation information is cached on the Eureka clients. This ensures that the mutual invocation between our microservices is robust enough.Beyond that, the powerful open source power behind spring cloud Netflix has prompted us to choose Spring Cloud Netflix: As mentioned earlier, the community of Spring Cloud is very active, its applicatio
