容器为运行服务提供了一致、可复制的环境。如Kubernetes等容器编排（Orchestration）系统，可以用一致的API，帮助我们管理和伸缩容器集群。对于松散耦合的微服务架构而言，这是很好的起点，不过还不够。如何控制服务间的流量和实施策略？如何将服务间的依赖可视化，并快速识别问题？如何提供可验证的服务特性，来处理和测试故障？开发者可以实现自己的定制方案，也可以依赖Istio这一开放平台来连接和管理微服务，并保障安全。在本次演讲中，我们将学习Istio的主要特性，并理解其对微服务网络的助力作用。

Containers provide a consistent and reproducible environment to run our services. Orchestration systems like Kubernetes help us to manage and scale our container cluster with a consistent API. This is a good start for a loosely coupled microservices architecture but it is not enough. How do you control the flow of traffic and enforce policies between services? How do you visualize service dependencies and quickly identify issues? How can you provide verifiable service identities, handle and test for failures? You can implement your own custom solutions or you can rely on Istio, an open platform to connect, manage and secure microservices. In this talk, we will take a look at some of the key capabilities of Istio and see how it can help with your microservices network.
