Nacos 生态 其中主要涉及到数据面的代理服务 Proxy，集群入口网关 Ingress、集群出口网关 Egress 以及核心 控制面 Istiod。各个组件的功能如下：  代理服务 Proxy 采用的 Lyft 公司开源的高性能 C++ 网络代理 Envoy，拦截业务的所有出入流 量。  入口网关 Ingress，作为集群的访问入口，控制着集群内部服务如何安全的暴露出去，并对所有 入口流量进行统⼀控制和观测。 入口流量进行统⼀控制和观测。  出口网关 Egress，作为集群的访问出口，控制着集群内部服务如何安全的访问外部服务。  核心控制面 Istio 负责对所有数据面的代理服务 （包括 Ingress、Egress 网关）下发服务发现 信息，流量治理配置，以及用于服务之间进行双向认证的 TLS 证书。 可以看出 Istiod 是微服务领域的集大成者，覆盖了服务发现、服务治理、认证鉴权和可观测，以无 服务网格时代的 Nacos 随着云原生技术的发展和微服务 2.0 架构的提出，很多公司正在尝试通过服务网格技术去解决微服 务 1.0 架构中的问题。在微服务架构 2.0 架构中，流量是通过 ingress 网关接入的，进入微服务 体系，与 1.0 架构不同的是引入了数据面 Envoy 和控制面 Istio，Envoy 以 Sidecar 模式与应用部 署在同⼀个 Pod 中，会劫持应用的进出流量，然后可以通过控制面
