Permissions Management

If you need to assign different permissions to employees in your enterprise to access your OCR 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.

If your Huawei Cloud account does not require individual IAM users for permissions management, skip this section.

With IAM, you can use your Huawei Cloud account to create IAM users, and grant permissions to the users to control their access to specific resources. For example, some software developers in your enterprise need to use OCR but should not be allowed to delete other OCR resources or perform any other high-risk operations. In this scenario, you can create IAM users for the software developers and grant them only the permissions required for using OCR resources.

IAM is free of charge. You pay only for the resources you use. For more information about IAM, see IAM Service Overview.

OCR Permissions

By default, new IAM users do not have permissions assigned. You need to add a user to one or more groups, and attach permissions policies or roles to these groups. Users inherit permissions from the groups to which they are added and can perform specified operations on cloud services based on the permissions.

OCR is a project-level service deployed and accessed in specific physical regions. To assign OCR permissions to a user group, specify the scope as region-specific projects and select projects such as ap-southeast-1 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 OCR, the users need to switch to a region where they have been authorized to use this service.
