Basic Concepts

Organization

An organization is an entity that you create to manage multiple accounts. Each organization is composed of one management account, multiple member accounts, a root, and OUs. An organization has exactly one management account along with several member accounts. You can organize the accounts in a hierarchical, tree-like structure with the root OU at the top and nested OUs under it. Each member account can be directly under the root or placed under one of the OUs. For details about how to manage organizations, see Managing Organizations.

Root OU

Organizations automatically generates the root for you when you enable Organizations to create an organization. The root OU is located at the top of the tree, and its branches represent other OUs and accounts reaching down.

OUs

An OU is a container or grouping unit for member accounts. It can be understood as a department, a subsidiary, a project team, or the like, of your enterprise. An OU can also contain other OUs. Each OU can have exactly one parent OU, but a parent OU can have multiple child OUs or nested member accounts. For details about how to manage OUs, see Managing OUs.

Service Control Policies

Service control policies (SCPs) are a type of organization policy that you can use to manage permissions in your organization. The management account can use SCP to limit the permissions that can be assigned to member accounts in an organization. You can attach an SCP to your organization, OUs, or member accounts. Any SCP attached to an organization or OU affects all the accounts within the organization or under the OU. For details about how to manage SCPs, see Managing SCPs.

Tag Policies

Tag policies are a type of policy that can help you standardize tags across resources in your organization's accounts. A tag policy is only applied to tagged resources and tags that are defined in that policy. For details about how to manage tag policies, see Managing Tag Policies.

Trusted services

A trusted service is a Huawei Cloud service that is entrusted by Organizations to provide organization-wide capabilities. The management account can enable a cloud service as a trusted service with Organizations. Each trusted service has access to the information about the OUs and member accounts in your organization and also can manage the entire organization. For details about how to manage trusted services, see Managing Trusted Services.

URN

A uniform resource name (URN) is used to uniquely identify a cloud service resource.

A URN is in the following format: <service-name>:<region>:<account-id>:<type-name>:<resource-path>

• service-name: the abbreviation of a cloud service name in lowercase, for example, ecs. The abbreviation must be valid and cannot be a wildcard.
• region: the region where the resource is located, for example, cn-north-1. If the resource is a global service resource, leave this field blank or use asterisks (*) to replace it.
• account-id: the ID of the account. The value system indicates public system resources, such as system-defined policies.
• type-name: the resource type in lower camel case.
• resource-path: the resource path whose format is defined by the cloud service.
