Using IAM Identity Policies to Grant Access to Cost Center

System-defined permissions in identity-based authorization provided by Identity and Access Management (IAM) let you control access to Cost Center. With IAM, you can:

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

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

Figure 1 shows the process flow of identity policy-based authorization.

Prerequisites

Before granting permissions, learn about system-defined permissions in Identity Policy-based Authorization for Cost Center. To grant permissions for other services, learn about all system-defined permissions supported by IAM.

Process Flow

Figure 1 Process of granting Cost Center permissions using identity policy-based authorization
  1. On the IAM console, create an IAM user or create a user group.
  2. Attach a system-defined identity policy (CostCenterReadOnlyPolicy as an example) to the user or user group.

    Assign the permissions defined in the system-defined identity policy CostCenterReadOnlyPolicy to the user or group, or attach the system-defined identity policy to it.

  3. Log in as the IAM user and verify permissions.

    In the authorized region, perform the following operations:

    • In the upper right corner of the Huawei Cloud official website, choose Billing & Costs from the drop-down list of your login account. Then, click Cost Center to check if you have the query permission. If you have, the CostCenterReadOnlyPolicy policy is in effect.
    • Add or delete data on any page in Cost Center. If a message appears indicating that you have insufficient permissions to perform the operation, the CostCenterReadOnlyPolicy policy is in effect.

Example Custom Identity Policies

You can create custom identity policies to supplement the system-defined identity policies of Cost Center. For details about actions supported in custom identity policies, see Actions Supported by Identity Policy-based Authorization.

To create a custom identity policy, choose either visual editor or JSON.

  • Visual editor: Select cloud services, actions, resources, and request conditions. This does not require knowledge of policy syntax.
  • JSON: Create a JSON policy or edit an existing one.

For details, see Creating a Custom Identity Policy and Attaching It to a Principal. The following provides examples of custom Cost Center identity policies.

  • Example 1: Grant permission to view cost analyses and add/modify budget reports. 
    {
    "Version": "5.0",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "costCenter:costAnalysis:listCosts",
                "costCenter:budget:configBudgetReport"
            ]
        }
    ]
}
  • Example 2: Grant permission to view cost analyses and configure cost budgets in Cost Center, and export the bill summary in Billing Center.

    A custom policy can contain the actions of one or multiple services.

    Example policy containing multiple actions:

    {
    "Version": "5.0",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "costCenter:costAnalysis:listCosts",
                "costCenter:budget:configBudget"
            ]
        },
        {
            "Effect": "Allow",
            "Action": [
                "billing:bill:export"
            ]
        }
    ]
}
