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 passwords and grant permissions. The account is a payment entity, which should not be used directly to perform routine management. For security purposes, create Identity and Access Management (IAM) users and grant them permissions for routine management.

  • User

    A user is created in IAM using an account to use cloud services. Each 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 account name, username, and password are required for API authentication.

  • Region

    A region is a physical location where cloud resources are deployed. Availability zones (AZs) in the same region can communicate with each other over an intranet but AZs in different regions cannot communicate with each other. Deploying cloud resources in different regions can better suit certain user requirements or comply with local laws or regulations.

  • Availability Zone (AZ)

    An AZ comprises of one or more physical data centers equipped with independent ventilation, fire, water, and electricity facilities. Computing, 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 users to build cross-AZ high-availability systems.
