While evolving towards a microservices architecture, the biggest change is that the monolith application has been divided into multiple independent processes(or services), as a result, a method call between software modules now becomes a remote procedure call go through multiple services. A client request usually goes through a couple of or even a dozen of services in a complex microservices system, which makes it really hard to figure out w

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。

奇妙的 2019 KubeCon + ClondNativeCon + Open Source Summit 大会！在这里，我近距离接触了大神 Linus；见到了来自 ServiceMesher 社区的很多朋友；还遇到了搞 Kubernetes 的恩格斯后人!

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?
