Basic 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 user passwords and grant user permissions. The account is a payment entity and should not be used directly to perform routine management. For security purposes, create IAM users and grant them permissions for routine management.

  • IAM user

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

    An IAM user can view the account ID and user ID on the My Credentials page of the console. The domain name, username, and password will be required for API authentication.

  • Region

    Regions are divided from the dimensions of geographical location and network latency. Public services, such as elastic computing, block storage, object storage, VPC network, elastic public IP address, and image, are shared in the same region. Regions are classified into universal and dedicated regions.

    • A universal region provides universal cloud services for common tenants.
    • A dedicated region provides specific services for specific tenants.
  • Availability zone (AZ)

    An AZ contains one or more physical data centers. Each AZ has independent cooling, fire extinguishing, moisture-proof, and electricity facilities. Within an AZ, compute, network, storage, and other resources are logically divided into multiple clusters. AZs within a region are interconnected using high-speed optical fibers to support cross-AZ high-availability systems.

  • Enterprise project

    An enterprise project groups and manages enterprise resources in a logically isolated manner. It can contain resources in multiple regions, and allow resources to be added or removed.

    For details about how to obtain enterprise project IDs and features, see the Enterprise Management User Guide.
