Authorizing IAM Users to Manage Resources of an Account

Requirements

• Company B wants to authorize its employees (IAM users) to manage the delegated resources of company A.
• If company A creates multiple agencies for company B, company B can allocate the agencies to different employees. This will allow each employee to only manage resources of specific agencies.

Solution

• Account B creates users on the IAM console, and grants the permissions (including Agent Operator) required for managing delegated resources to the users.
• Account B creates a custom policy with only the permissions required to manage the delegated resources of an agency. Then, account B attaches the policy to the group to which a user belongs, so that the user can only manage the resources of the agency.

Procedure

Account B performs the following procedure to authorize IAM users to manage resources of specific agencies. After authorization, the IAM users of account B can switch their roles to account A to manage account A's resources. To do this, account B needs to have obtained the account (HUAWEI ID), agency name, and agency ID of the delegating party.
