Service Mesh和SDN(Software Defined Network) 的架构非常相似，这两者都采用了软件对网络进行管理和控制，也都包含控制面和数据面的概念。那么Service Mesh和SDN有什么关系？Service Mesh是下一代的SDN吗？ Service Mesh可以从SDN的发展历史中借鉴哪些经验？本文将就这些问题进行一一探讨。

在Istio架构中，Pilot组件属于最核心的组件，负责了服务网格中的流量管理以及控制面和数据面之间的配置下发。Pilot内部的代码结构比较复杂，本文中我们将通过对Pilot的代码的深入分析来了解Pilot实现原理。

In this post, we will continue to use the eshop demo to explore how asynchronous messaging, specifically Kafka, can be traced in Istio service mesh with the help of Opentracing.

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。
