+## Introduction
+
+<!-- DOCS_DESCRIPTION_CN -->
+本示例用于实现解决方案[Redis 通过 Proxy 组件实现读写分离](https://www.aliyun.com/solution/tech-solution/read-write-splitting-through-tair-proxy), 涉及到专有网络（VPC）、交换机（VSwitch）、云服务器（ECS）、云数据库 Tair（兼容 Redis）等资源的创建。
+<!-- DOCS_DESCRIPTION_CN -->
+
+<!-- DOCS_DESCRIPTION_EN -->
+This example demonstrates the implementation of the solution [Read write splitting through tair proxy](https://www.aliyun.com/solution/tech-solution/read-write-splitting-through-tair-proxy). It involves the creation, and deployment of resources such as Virtual Private Cloud (VPC), VSwitch, Elastic Compute Service (ECS), and Tair (Redis OSS-compatible).
