本文为您介绍服务关联角色AliyunServiceRoleForCEN以及如何删除该服务关联角色。

背景信息

服务关联角色SLR(Service Linked Role)是指与某个云服务关联的RAM角色。在某些场景下,为了完成云服务的某个功能,需要获取其他云服务的访问权限。通过服务关联角色,您可以更好地创建云服务正常操作所需的权限,避免误操作带来的风险。关于服务关联角色的更多信息,请参见服务关联角色

创建服务关联角色AliyunServiceRoleForCEN

您在企业版转发路由器中创建专有网络VPC(Virtual Private Cloud)网络实例连接时,系统将会为您自动创建一个名称为AliyunServiceRoleForCEN的服务关联角色,并且为该角色添加名称为AliyunServiceRolePolicyForCEN的权限策略,该权限会允许企业版转发路由器在VPC中创建弹性网卡,作为VPC发往企业版转发路由器的流量入口。权限策略内容如下:

说明 如果服务关联角色AliyunServiceRoleForCEN已存在,系统则不会重复创建。
