+## Introduction
+<!-- DOCS_DESCRIPTION_CN -->
+本示例用于实现解决方案[自建数据库迁移到云数据库](https://www.aliyun.com/solution/tech-solution/mysql-rds), 涉及到专有网络（VPC）、交换机（VSwitch）、云服务器（ECS）、云数据库（RDS）MySQL版等资源的部署。
+<!-- DOCS_DESCRIPTION_CN -->
+
+<!-- DOCS_DESCRIPTION_EN -->
+This example is used to implement solution [Migrate Self-Built Database to Cloud Database](https://www.aliyun.com/solution/tech-solution/mysql-rds), which involves the creation and deployment of resources such as Virtual Private Cloud (VPC), VSwitch, Elastic Compute Service (ECS), ApsaraDB RDS.
