Istio 是个开放平台（非 Kubernetes 特有），提供了一种统一的方式来集成微服务、管理流量、实施策略和汇总度量数据。

Adding Istio does not require changing application code. It is a layer of infrastructure between a service and the network, which when combined with service deployments, is commonly referred to as a service mesh. Istio's control plane abstracts away the underlying cluster management platform, which may be Kubernetes, Mesosphere, etc.

添加 Istio 时不需要修改应用代码。它是基础设施的一层，介于服务和网络之间。当它和服务的 Deployment 相结合时，就构成了通常所谓的服务网格（Service Mesh）。Istio 的控制面抽象掉了底层的集群管理平台，这一集群管理平台可以是 Kubernetes、Mesosphere 等。
