Spring Cloud Spring Cloud provides developers with the tools to quickly build common patterns in distributed systems (such as configuration management, service discovery, circuit breakers, intelligent routing, micro-proxies, control buses). The coordination of distributed systems has led to boilerplate patterns, and the use of spring cloud developers can quickly support services and applications that implement these patterns. They will work well in any distributed environment, including develop

1. ReviewIn a previous blog, a single-node Eureka Server was implemented. Eureka client periodically connects to Eureka Server, obtains information from the registry, and caches it locally. MicroServices always use data from the local cache when consuming remote APIs. As a result, in general, even if the Eureka server

Objective Starting from this section, formally enter SpringCloud the basic tutorial. From the first chapter "What is Springcloud" we can know that a microservices framework covers a lot of things, and how to manage these services or API interfaces, it is very important. So in this chapter, we mainly introduce the SpringCloud Eureka implementation of service registration and discovery.

In peacetime work, Eureka as a cluster, we will configure multiple peers, assuming that there is currently a server eureka-a,eureka-b,eureka-c.if the peer of Eureka a points to B and the peer of B points to C, then when the service registers with a, there is a registration i

First, Eureka Meta-data1.1. IntroductionThere are two types of metadata for Eureka: standard metadata and custom metadata.Standard metadata refers to information such as host name, IP address, port number, status page, and health check, which are published in the service registry for calls between services.Custom metadata can use the Eureka.instance.metadata-map configuration, which can be accessed in remot

Spring Cloud Eureka is part of the spring cloud Netflix MicroServices Suite, which has two packages based on Netflix Eureka and is primarily responsible for service governance capabilities in the MicroServices architecture.Service governance:Service governance can be said to be the most core and basic module in the micro-service architecture, it mainly realizes the automatic registration and discovery of ea

Spring Cloud EurekaSpring Cloud is one of the mainstream frameworks currently used to develop microservices, and we all know that the most basic and core modules in the MicroServices architecture are service registration and discovery.In spring cloud, we can use its Eureka module for service registration and discovery, and Spring Cloud Eureka is based on the Netflix Eur
