Istio实战系列-Envoy Proxy构建分析

Istio由控制面和数据面组成。其中Envoy是Istio在数据面缺省使用的转发代理,Istio利用Envoy的四层和七层代理功能对网格中微服务之间的调用流量进行转发。今天我>们来分析一下Istio 使用到的Envoy构建流程。

Istio微服务平台集成实践

Istio发布1.0版本后,其服务发现和路由规则功能已基本具备production能力,我们也开始了Istio和公司内部微服务平台的集成工作,打算以Istio为基础打造一个微服务管控中心,在这里把目前的进展和遇到的坑和大家分享一下。

Istio流量管理实现机制深度解析

Istio作为一个service mesh开源项目,其中最重要的功能就是对网格中微服务之间的流量进行管理,包括服务发现,请求路由和服务间的可靠通信。Istio体系中流量管理配置下发以及流量规则如何在数据面生效的机制相对比较复杂,通过官方文档容易管中窥豹,难以了解其实现原理。本文尝试结合系统架构、配置文件和代码对Istio流量管理的架构和实现机制进行分析,以达到从整体上理解Pilot和Envoy的流量管理机制的目的。

Secure ONAP Microservices with Istio Mutual TLS Authentication and RBAC

In the previous post Manage ONAP Microservices with Istio Service Mesh, we went through the steps of how to install Istio and integrate it with ONAP platform, it’s super simple and has nearly no impact to the existing projects. Now let’s enable Istio auth to secure the inter-service communication inside ONAP, it will need a little bit more efforts, but it’s worth with the benefits brought by it. Installation Download installation scripts from ONAP Gerrit:

Manage ONAP Microservices with Istio Service Mesh

In the previous post How service mesh can help during the ONAP Microservice journey, we have discussed why the community wants ONAP to evolve towards Microservice architecture and how service mesh approach could help during the journey. Now it’s time to dip our toe in the water, let’s try out Istio with ONAP by following the below steps. Installation First, download installation scripts from ONAP Gerrit: git clone https://gerrit.onap.org/r/msb/service-mesh Kubernetes Master We need Kubernetes 1.
