什么是DMS的服务关联角色_数据管理（兼容数据库备份）(DMS)-阿里云帮助中心

本文介绍数据管理DMS和数据灾备（DBS）服务关联角色（AliyunServiceRoleForDMS、AliyunServiceRoleForDBS）的应用场景以及如何删除服务关联角色。

背景信息

服务关联角色是一种RAM角色（RAM role）。在某些场景下，该角色可以帮助数据管理DMS和数据灾备（DBS）获取到其他云服务的访问权限，来实现自身的某个功能。更多关于服务关联角色的信息，请参见服务关联角色。

应用场景

数据管理DMS

当DMS部分功能需要访问ECS、VPC、RDS以及各类型数据库或工具相关的资源时，您可以通过DMS服务关联角色获取访问资源的权限。

数据灾备（DBS）

DBS服务关联角色（AliyunServiceRoleForDBS）是具备其他云服务访问权限的RAM角色，DBS接入您在阿里云购买的云数据库（如RDS、MongoDB、 Redis、PolarDB）或阿里云ECS上自建的数据库时，需通过AliyunServiceRoleForDBS获取访问权限。更多信息，请参见服务关联角色。

角色介绍

AliyunServiceRoleForDMS

角色名称：AliyunServiceRoleForDMS

策略名称：AliyunServiceRolePolicyForDMS

权限说明：创建该关联角色后，DMS即可访问ECS、VPC、RDS以及各类型数据库或工具相关的资源。

权限的作用

查询RDS、PolarDB、Lindorm等各类型数据库的资源详情，以便管理云数据库。
查询ECS、VPC的资源详情，以便管理ECS、公网自建数据库。
使用DTS、DBS等云生态工具，进行一站式的数据管理。
