Concepts

  • Account

    An 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 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 through internal network connections. Deploying cloud resources in different regions can better suit certain user requirements or comply with local laws or regulations.
  • 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, computing, 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.
  • Project

    Projects group and isolate resources (including compute, storage, and network resources) across physical regions. A default project is provided for each 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.

  • 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 in multiple regions, and resources can be directly transferred between enterprise projects.
