Concepts

  • Account

    An account is created upon successful registration with Huawei Cloud. The account has full access permissions for all of its cloud services and resources. It can be used to reset passwords and grant permissions. The account is a payment entity and should not be used directly to perform routine management. For security purposes, create users and grant them permissions for routine management.

  • IAM User

    An IAM user is created using an account to use cloud services. Each IAM user has its own identity credentials (password and access keys)

    The account name, username, and password will be required for API authentication.

  • Region

    Regions are geographic areas isolated from each other. Resources are region-specific and cannot be used across regions. For low network latency and quick resource access, select the nearest region. The choice of regions may also be subject to legal compliance requirements.

  • AZ

    An AZ comprises one or multiple physical data centers equipped with independent ventilation, fire, water, and electricity facilities. Compute, network, storage, and other resources in an AZ are logically divided into multiple clusters. AZs within a region are interconnected using high-speed optical fibers to allow you to build highly available systems across AZs.

  • Project

    A project corresponds to a Huawei Cloud region. Default projects are defined to group and physically isolate resources (including compute, storage, and network resources) across regions. Users can be granted permissions in a default project to access all resources in the region associated with the project. If you need more refined access control, create subprojects under a default project and create resources in subprojects. Then you can assign users the permissions required to access only the resources in the specific subprojects.

  • Enterprise Project

    Enterprise projects group and manage resources across regions. Resources in enterprise projects are logically isolated from each other. An enterprise project can contain resources of multiple regions, and resources can be added to or removed from enterprise projects.

    For more information about enterprise projects and how to obtain enterprise project IDs, see the Enterprise Management User Guide.
