Using IAM Roles or Policies to Grant Access to MPC

System-defined permissions in role/policy-based authorization provided by Identity and Access Management (IAM) let you control access to MPC. With IAM, you can:

  • Create IAM users for personnel based on your enterprise's organizational structure. Each IAM user has their own identity credentials for accessing MPC resources.
  • Grant users only the permissions required to perform a given task based on their job responsibilities.
  • Entrust a Huawei Cloud account or a cloud service to perform efficient O&M on your MPC resources.

If your Huawei Cloud account meets your permissions requirements, you can skip this section.

Figure 1 shows the process of role/policy-based authorization.

Prerequisites

Before granting permissions to user groups, learn about system-defined permissions in Role/Policy-based Authorization for MPC. To grant permissions for other services, learn about all system-defined permissions supported by IAM.

Process Flow

Figure 1 Process of granting MPC permissions
  1. On the IAM console, create a user group and grant it permissions.

    Create a user group on the IAM console and assign the MPC Administrator permissions to the group.

  2. Create an IAM user and add it to the created user group.

    On the IAM console, create a user and add it to the user group created in 1.

  3. Logging in as the IAM user and verifying permissions

    In the authorized region, perform the following operations:

    • Choose Media Processing Center in Service List. In the navigation pane on the left, choose Media Processing > Transcode. On the page that is displayed, create a transcoding task. If the transcoding is successful, the MPC Administrator policy is in effect.
    • Choose another service in Service List. If a message is displayed indicating insufficient permissions for performing the operation, the MPC Administrator policy is in effect.
