Permissions Management

If you need to assign different permissions to employees in your enterprise to access your Application Performance Management (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 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 must not 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 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.

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

Table 1 lists all the 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 appropriate policies or roles as required.
