Permissions Management

If you need to assign different permissions to employees in your enterprise to access your APM resources, Identity and Access Management (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 cloud resources.

With IAM, you can use your Huawei Cloud account to create IAM users for your employees, and assign permissions to the users to control their access to specific resources. For example, some software developers in your enterprise need to use APM resources but cannot delete them or perform any high-risk operations. To achieve this result, you can create IAM users for the software developers and grant them only the permissions required for using APM resources.

If your Huawei Cloud account does not need individual IAM users for permissions management, you may skip over this chapter.

IAM can be used free of charge. You pay only for the resources in your account. For more information about IAM, see IAM Service Overview.

APM Permissions

By default, new IAM users do not have any permissions assigned. You need to add a user to one or more groups, and assign permissions policies or roles to these groups. The user then inherits permissions from the groups it is a member of. This process is called authorization. After authorization, the user can perform specified operations on APM.

APM is a global service. By default, the APM permissions granted to a user take effect in all regions supported by APM. APM resources are isolated by tenant. All users under a tenant share resources. To isolate resources, use enterprise projects.

APM is a global service and can be accessed without specifying a physical region. During authorization, choose Enterprise > Project Management to set permissions.

Table 1 lists all the system permissions supported by APM.

**Table 1** System permissions supported by APM
Role	Description	Category
APM FullAccess	Full permissions for APM	System-defined policy
APM ReadOnlyAccess	Read-only permissions for APM	System-defined policy

Table 2 lists the common operations supported by each system-defined policy or role of APM. Choose policies or roles as required.
