基础架构:
Eureka的基本功能:
eueka按逻辑上可以划分为3个模块，eureka-server，service-provider，service-consumer
eureka-server：服务端，提供服务注册和发现
eureka-client-service-provider：服务端，服务提供者，通过http rest告知服务端注册，更新，取消服务
eureka-client-service-consumer：客户端，服务消费者，通过http rest从服务端获取需要服务的地址列表，然后配合一些负载均衡策略（ribbon）来调用服务端服务。
值得注意的一点，不同于其他服务注册与发现(zookeeper需要单独以中间件的形式部署集群server)，以上3个角色都是逻辑角色，甚至可以在相同的jvm进程上
注意：在该默认配置下，注册中心也会将自己作为客户端尝试注册自己，因此要禁用客户端注册行为
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
