Role planning and management - Permission Management| Alibaba Cloud Documentation Center

A role is a set of permissions. You can use a role to grant the same set of permissions to multiple users. Role-based authorization helps simplify the authorization process and reduce permission management costs. If you want to grant the same set of permissions to multiple users, we recommend that you use role-based authorization. This topic describes the role types that are supported by MaxCompute and the operations that you can perform on different types of roles.

Background information

MaxCompute provides the following built-in tenant-level roles: Super_Administrator and Admin. MaxCompute also provides the following built-in project-level roles: Project Owner, Super_Administrator, and Admin.

In addition, MaxCompute allows you to create custom roles based on your business requirements, and classify and manage users based on roles.

The following table describes the role types that are supported by MaxCompute.


Role type	Role name	Description
Tenant-level roles	Super_Administrator	A built-in administrator role that is provided by MaxCompute. This role has all the permissions that an Alibaba Cloud account has on MaxCompute, except for the permissions to create a project, delete a project, and activate the MaxCompute service.
Tenant-level roles	Admin	A built-in administrator role that is provided by MaxCompute. This role has the permissions to manage all objects and network connections.
Project-level roles	Project Owner	The owner of a project. After a user creates a MaxCompute project, the user becomes the owner of the project and has all permissions on the project. Only the owner of a project has the permissions to access objects in the project. Other users cannot access the objects in the project unless they are granted the required permissions by the project owner.
	Super_Administrator	A built-in administrator role that is provided by MaxCompute. This role has the operation permissions on all resources in a project and all management permissions. For more information about the permissions of the Super_Administrator role, see Permissions of project-level administrator roles. The project owner or users that are assigned the Super_Administrator role can assign the Super_Administrator role to other users.
	Admin	A built-in administrator role that is provided by MaxCompute. This role has the operation permissions on all resources in a project and some basic management permissions. For more information about the permissions of the Admin role, see Permissions of project-level administrator roles. The project owner can assign the Admin role to other users. A user that is assigned the Admin role cannot assign the Admin role to other users, configure security policies for the project, modify the authentication models of the project, or modify the permissions of the Admin role.
	Custom role	A custom role of MaxCompute.

The following table describes the role management operations that are supported by MaxCompute.

Create a project-level role

You can create a role in a MaxCompute project.

Syntax
```
create role <role_name>;
```

Parameter


Parameter	Required	Description
role_name	Yes	The name of the role. The name must be unique within a project. When you specify a name for the role, take note of the following items: The name must start with a letter. The name can contain only letters and digits. The name cannot exceed 64 characters in length. You can run the `list roles;` command on the MaxCompute client to query the existing roles in a project.

Example
Create a role named Worker. Sample command:
```
create role Worker;
```

Query the project-level roles

You can query the existing roles in a project.

Syntax
```
list roles;
```
Example

super_administrator
worker
```

Drop a project-level role

You can drop a role from a project.

Syntax
```
drop role <role_name>;

Precautions
When you drop a role, MaxCompute checks whether the role is assigned to users. If the role is assigned to users, the role cannot be dropped. You can drop the role only after you revoke the role from all users that are assigned the role. For more information about how to revoke a role from a user, see Revoke a role from a user.

What to do next

After you plan and create a role, you can grant the required permissions to the role based on your business requirements. For more information, see Perform role-based access control.
