Permission Management

If you need to assign different permissions to employees in your enterprise to access your DataArts Studio resources, IAM is a good choice for fine-grained permissions management. IAM provides identity authentication, permissions management, and access control, helping you secure access to your Huawei Cloud resources.

With IAM, you can use your Huawei Cloud account to create IAM users for your employees, and assign permissions to the users to control their access to specific resource types. For example, if you want to allow some software developers in your enterprise to use DataArts Studio resources but disallow them to delete workspaces or perform any high-risk operations, you can create IAM users for the software developers and grant them only the permissions required for using DataArts Studio resources.

IAM is a free service. You only pay for the resources in your account. For more information about IAM, see IAM Service Overview.

DataArts Studio Permissions

By default, new IAM users do not have any permissions. To assign permissions to a user, add the user to one or more groups and assign permissions policies or roles to these groups. The user then inherits permissions from the groups it is a member of After authorization, the users can perform specified operations.

DataArts Studio is a project-level service deployed in specific physical regions. To assign ServiceStage permissions to a user group, specify the scope as region-specific projects and select projects for the permissions to take effect. If All projects is selected, the permissions will take effect for the user group in all region-specific projects. When accessing DataArts Studio, users need to switch to a region where they are authorized to use cloud services.

DataArts Studio supports only system role-based authorization and does not support policy-based authorization. To implement fine-grained permission control, DataArts Studio provides the capability of granting permissions to system roles and workspace roles. Specific operation permissions are granted to workspace roles, and workspace roles with different permissions can be customized.

IAM provides the following two authorization mechanisms: Note that DataArts Studio supports only the IAM role-based authorization and does not support the IAM policy-based authorization.

IAM Roles: IAM initially provides a coarse-grained authorization mechanism to define permissions based on users' job responsibilities. This mechanism provides only a limited number of service-level roles for authorization. However, traditional IAM roles are not an ideal choice for fine-grained authorization and secure access control.
IAM Policies: A type of fine-grained authorization mechanism that defines permissions required to perform operations on specific cloud resources under certain conditions. This type of authorization is more flexible and is ideal for least privilege access.

As shown in Figure 1 and Table 1, the system-defined roles supported by DataArts Studio include DAYU Administrator and DAYU User. Workspace roles are based on the DAYU User. Permissions lists the common operations supported by DataArts Studio and the permissions granted to each role. You can select roles as required.

**Table 1** DataArts Studio system-defined roles
Role	Description	Category
DAYU Administrator	Instance administrator who has all management permissions on a DataArts Studio instance and its workspaces, permissions of dependent services, and service operation permissions in all workspaces. NOTE: Users assigned the Tenant Administrator role have all permissions for all services except IAM. In other words, users with the Tenant Administrator role can perform all operations in DataArts Studio.	System-defined role
DAYU User	Common user who has permissions to view a DataArts Studio instance and its workspaces, and the permissions of dependent services. After assigned a role, a common user has permissions of the role to perform service operations. Workspace roles include the preset admin, developer, deployer, operator, and viewer. For details about the operation permissions of each role, see Permissions. Admin: This role has all operation permissions in a workspace. You are advised to assign the admin role to the project owner, development owner, and O&M administrator. Developer: This role has permissions to create and manage resources in a workspace. You are advised to assign this role to users who develop and process tasks. Operator: This role has the operation permissions of services such as O&M and scheduling in a workspace, but cannot modify resources or configurations. You are advised to assign this role to users responsible for O&M management and status monitoring. Viewer: This role can view data in a workspace but cannot perform any other operation. You are advised to assign this role to users who only need to view data in a workspace but do not need to perform operations. Deployer: This role is unique to the enterprise mode and has permissions to release task packages in a workspace. In enterprise mode, when a developer submits a script or job version, the system generates a release task. After the developer confirms the release and the deployer approves the release request, the modified job is synchronized to the production environment.	System-defined role

Roles or Policies for DataArts Studio Console

Table 2 lists the permissions for the services on which DataArts Studio components depend. You are advised to configure the minimum DataArts Studio-level permissions of dependent services for developers. (For details, see Authorizing IAM Users to Use DataArts Studio by Complying with the Principle of Least Privilege.) Table 3 lists the minimum permissions for developers on the services on which DataArts Studio depends.

The DAYU Administrator and DAYU User already have the administrator permissions of dependent services. If the DAYU User role is assigned to a common user or user group, the common user or user group may have more permissions of dependent services than required. To prevent this risk, you can manually delete the permissions of dependent services from the user group after assigning the DAYU User role to the user group, and then assign the minimum permissions of dependent services to the user group.
