如何降低Istio服务网格中Envoy的内存开销

在Istio服务网格中，每个Envoy占用的内存也许并不算多，但所有sidecar增加的内存累积起来则是一个不小的数字。在进行商用部署时，我们需要考虑如何优化并减少服务网格带来的额外内存消耗。

Service Mesher Meetup 成都站：Service Mesh是下一代SDN吗？

从SDN看Service Mesh的发展

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。

Enhance Istio Distributed Tracing with OpenTracing

Part 2: Enable Async Messaging Tracing with OpenTracing

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.

Enhance Istio Distributed Tracing with OpenTracing

Part 1: Implement Fine-grained Tracing with 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

洞若观火：使用OpenTracing增强Istio的调用链跟踪

第一篇：如何利用Opentracing实现方法级的细粒度跟踪

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。
