Agencies and Dependencies

Function Dependency

Function Dependency Policies

When using ModelArts to develop algorithms or manage training jobs, you are required to use other Cloud services. For example, before submitting a training job, select an OBS path for storing the dataset and logs, respectively. Therefore, when configuring fine-grained authorization policies for a user, the administrator must configure dependent permissions so that the user can use required functions.

Note

If you use ModelArts as the root user (default IAM user with the same name as the account), the root user has all permissions by default.

Agency authorization

To simplify operations when you use ModelArts to run jobs, certain operations are automatically performed on the ModelArts backend, for example, downloading the datasets in an OBS bucket to a workspace before a training job is started and dumping training job logs to the OBS bucket.

ModelArts does not save your token authentication credentials. Before performing operations on your resources (such as OBS buckets) in a backend asynchronous job, you are required to explicitly authorize ModelArts through an IAM agency. ModelArts will use the agency to obtain a temporary authentication credential for performing operations on your resources. For details, see Adding Authorization.

Figure 1 Agency authorization

As shown in Figure 1, after authorization is configured on ModelArts, ModelArts uses the temporary credential to access and operate your resources, relieving you from some complex and time-consuming operations. The agency credential will also be synchronized to your jobs (including notebook instances and training jobs). You can use the agency credential to access your resources in the jobs.

You can use either of the following methods to authorize ModelArts using an agency:

One-click authorization

ModelArts provides one-click automatic authorization. You can quickly configure agency authorization on the Global Configuration page of ModelArts. Then, ModelArts will automatically create an agency for you and configure it in ModelArts.

In this mode, the authorization scope is specified based on the preset system policies of dependent services to ensure sufficient permissions for using services. The created agency has almost all permissions of dependent services. If you want to precisely control the scope of permissions granted to an agency, use the second method.

Custom authorization

The administrator creates different agency authorization policies for different users in IAM, and configures the created agency for ModelArts users. When creating an agency for an IAM user, the administrator specifies the minimum permissions for the agency based on the user's permissions to control the resources that the user can access when they use ModelArts.

Risks in Unauthorized Operations

The agency authorization of a user is independent. Theoretically, the agency authorization scope of a user can be beyond the authorization scope of the authorization policy configured for the user group. Any improper configuration will result in unauthorized operations.

To prevent unauthorized operations, only a tenant administrator is allowed to configure agencies for users in the ModelArts global configuration to ensure the security of agency authorization.

Minimal Agency Authorization

When configuring agency authorization, an administrator must strictly control the authorization scope.

ModelArts asynchronously and automatically performs operations such as job preparation and clearing. The required agency authorization is within the basic authorization scope. If you use only some functions of ModelArts, the administrator can filter out the basic permissions that are not used according to the agency authorization configuration. Conversely, if you need to obtain resource permissions beyond the basic authorization scope in a job, the administrator can add new permissions to the agency authorization configuration. In a word, the agency authorization scope must be minimized and customized based on service requirements.

Basic Agency Authorization Scope

To customize the permissions for an agency, select permissions based on your service requirements.
