Permissions Management

If you need to assign different permissions to personnel in your enterprise to access your SDRS resources, Identity and Access Management (IAM) is a good choice for fine-grained permissions management. IAM provides identity authentication, permissions management, and access control, helping you to securely access your Huawei Cloud resources.

With IAM, you can use your HUAWEI ID to create IAM users, and assign permissions to the users to control their access to specific resources.

If your HUAWEI ID does not require individual IAM users for permissions management, skip this section.

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

SDRS Permissions

By default, new IAM users do not have permissions. To assign permissions to new users, add them to one or more groups, and grant permissions to these groups. The users then inherit permissions from the groups to which the users belong, and can perform specific operations on cloud services.

SDRS is a project-level service deployed and accessed in specific physical regions. To assign SDRS permissions to a user group, specify the scope as region-specific projects and select projects (such as ap-southeast-2) 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 SDRS, the users need to switch to a region where they have been authorized to use SDRS.

Table 1 lists all the system-defined roles supported by SDRS. This role is dependent on other roles. When assigning SDRS roles to a user, you need to also assign the dependent roles to the user for the SDRS permissions to take effect.

**Table 1** System-defined roles supported by SDRS
Role Name	Description	Dependencies
SDRS Administrator	Administrator permissions for SDRS	Dependent on the Tenant Guest, Server Administrator, and VPC Administrator policies. Tenant Guest: A global policy, which must be assigned in the Global project. Server Administrator: A project-level policy, which must be assigned in the same project as the SDRS Administrator policy. VPC Administrator: A project-level policy, which must be assigned in the same project as the SDRS Administrator policy.
