Concepts

An account is created when you successfully sign up for Huawei Cloud. An account has full access permissions for all the resources and cloud services. It can be used to reset user passwords and grant users permissions. The account is a payment entity. For security purposes, do not directly use the account to perform routine management. Instead, create IAM users and grant them permissions for routine management.

A user is created in IAM to use cloud services. Each user has its own identity credentials (password and access keys).

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

Regions are geographic areas isolated from each other. Resources are region-specific and cannot be used across regions through internal network connections. For low network latency and quick resource access, select the nearest region.

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 you to build cross-AZ high-availability systems.

Projects group and isolate resources (including compute, storage, and network resources) across physical regions. A default project is provided for each Huawei Cloud region, and subprojects can be created under each default project. Users can be granted permissions to access all resources in a specific project. For more refined access control, create subprojects under a project and purchase resources in the subprojects. Users can then be assigned permissions to access only specific resources in the subprojects.

Figure 1 Project isolation model

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.
