Creating a User and Granting EVS Permissions

This chapter describes how to use IAM to implement fine-grained permissions control for your EVS resources. With IAM, you can:

Create IAM users for employees based on your enterprise's organizational structure. Each IAM user will have their own security credentials for accessing EVS resources.
Grant only the permissions required for users to perform a specific task.
Entrust a Huawei Cloud account or cloud service to perform professional and efficient O&M on your EVS resources.

If your Huawei Cloud account does not require individual IAM users, skip this chapter.

This section describes the procedure for granting permissions (see Figure 1).

Learn about the permissions (see EVS Permissions) supported by EVS and choose policies or roles according to your requirements.

Figure 1 Process for granting EVS permissions

Create a user group and assign permissions to it.
Create a user group on the IAM console, and attach the EVS ReadOnlyAccess policy to the group.
Create a user and add it to a user group.
Create a user on the IAM console and add the user to the group created in 1.
Log in and verify permissions.
Log in to the EVS console using the created user and verify that the user only has read permissions for EVS.
- In Service List, choose Elastic Volume Service. On the EVS console, click Buy Disk in the upper right corner. If a message appears indicating that you have insufficient permissions to perform the operation, the EVS ReadOnlyAccess policy has already taken effect.
- Choose any other service in Service List. If a message appears indicating that you have insufficient permissions to access the service, the EVS ReadOnlyAccess policy has already taken effect.
