本文将接着上一篇继续介绍如何利用OpenTracing来对Kafka异步消息进行跟踪，并将异步消息的跟踪信息加入Istio/Envoy生成的分布式调用跟踪链中进行统一呈现。

本文将介绍如何利用OpenTracing来增强Istio/Envoy缺省的调用链跟踪实现：如何利用Opentracing来实现跨进程边界的分布式调用上下文传递；以及在Istio/Envoy生成的分布式调用跟踪基础上实现方法级的细粒度调用跟踪。

By default, in a Kubernetes cluster with the Istio service mesh enabled, services can only be accessed inside the cluster. However, some of the services may need to be exposed to the external network as well. Kubernetes and Istio provide a variety of means to get external traffic into your cluster including NodePort, LoadBalancer, Kubernetes Ingress and Istio Gateway. With all these options, which one should be the right choice for your service mesh running in production?

在启用了Istio服务网格的Kubernetes集群中，缺省情况下只能在集群内部访问网格中的服务，要如何才能从外部网络访问这些服务呢？ Kubernetes和Istio提供了NodePort，LoadBalancer，Kubernetes Ingress，Istio Gateway等多种外部流量入口的方式，面对这么多种方式，我们在产品部署中应该如何选择？

本文将从代码出发，对Pilot的服务注册插件机制进行分析。
