You can grant permissions to a Resource Access Management (RAM) role that you created for a trusted Alibaba Cloud account, Alibaba Cloud service, or identity provider (IdP). This topic describes how to grant permissions to a RAM role.

Note You cannot grant permissions to service-linked roles by attaching policies to the roles. This is because the policies that are attached to this type of role are defined by the linked cloud services. For more information, see Service-linked roles.

Limits

You can attach up to 20 system policies and 5 custom policies to a RAM role.
