灵骏连接实例关联角色（AliyunServiceRoleForEfloVcc）的应用场景以及如何删除角色

开通灵骏连接后，用户可通过灵骏连接访问阿里云其他云产品（例如，访问VPC、创建专线、创建弹性网卡等），进行此类操作时需通过服务关联角色获取对应云产品的访问权限。本文为您介绍灵骏连接实例关联角色（AliyunServiceRoleForEfloVcc）的应用场景以及如何删除服务关联角色。

背景信息

灵骏连接服务关联角色（AliyunServiceRoleForEfloVcc）是在某些情况下，为了完成灵骏连接自身的某个功能，需要获取其他云服务的访问权限，而提供的RAM角色。更多关于服务关联角色的信息请参见服务关联角色。

创建服务关联角色

当您第一次创建集群，进行网络配置，您需要单击授权服务角色创建按钮，一键创建服务关联角色（AliyunServiceRoleForEfloVcc）。

删除服务关联角色

如果您需要删除AliyunServiceRoleForEfloVcc（服务关联角色），需要先释放依赖这个服务关联角色的灵骏连接。

释放灵骏连接可等云服务实例到期自动释放。
删除服务关联角色具体操作请参见删除服务关联角色。
