Introduction

You can use Identity and Access Management (IAM) to manage permissions on your Global Accelerator resources. If your HUAWEI ID does not need individual IAM users, you can skip over this section.

New IAM users do not have any permissions assigned by default. You need to first add them to one or more groups and attach policies or roles to these groups. The users then inherit permissions from the groups and can perform specified operations on cloud services based on the permissions they have been assigned.

You can grant users permissions by using roles and policies. Roles are provided by IAM to define service-based permissions that match users' job responsibilities. Policies define API-based permissions for operations on specific resources under certain conditions, allowing for more fine-grained, secure access control of cloud resources.

Policy-based authorization is useful if you want to allow or deny the access to an API.

An account has all of the permissions required to call all APIs, but IAM users must have the required permissions specifically assigned. The permissions required for calling an API are determined by the actions supported by the API. Only users who have been granted permissions allowing the actions can call the API successfully. For example, if an IAM user wants to query accelerators using an API, the user must have been granted permissions that allow the ga:accelerator:list action.

Supported Actions

Global Accelerator provides system-defined policies that can be directly used in IAM. You can also create custom policies to supplement system-defined policies for more refined access control. Operations supported by policies are specific to APIs. The following are common concepts related to policies:

Permissions: statements in a policy that allow or deny certain operations.
APIs: REST APIs that can be called by a user who has been granted specific permissions.
Actions: specific operations that are allowed or denied.
IAM projects/Enterprise projects: the authorization scope of a custom policy. A custom policy can be applied to IAM projects or enterprise projects or both. Policies that contain actions for both IAM and enterprise projects can be used and applied for both IAM and Enterprise Management. Policies that contain actions only for IAM projects can be used and applied to IAM only. For details about the differences between IAM and enterprise projects, see What Are the Differences Between IAM and Enterprise Management?

The check mark (√) indicates that an action takes effect and cross symbol (x) indicates that an action does not take effect for the corresponding type of projects.

Global Accelerator supports the following actions in custom policies:
