Scenarios

Certain ModelArts functions require the permission to access other services. This section describes how to assign specific permissions to IAM users when they use ModelArts.

Permissions

The permissions of IAM users are controlled by their tenant user. Logging in as a tenant user, you can assign permissions to the target user group through IAM. Then, the permissions are assigned to all members in the user group. The following authorization list uses the system-defined policies of ModelArts and other services as an example.
