Concepts

An account is created upon successful registration with the 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 users and grant them permissions for routine management.

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

A user can view the account ID and user ID on the My Credentials page of the console. 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.

AZs are physically isolated locations in a region, but are interconnected through an internal network for enhanced application availability.

A project corresponds to a region. Projects group and 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. For more refined access control, create subprojects under a project and create resources in the subprojects. Users can then be assigned permissions to access only specific resources in the subprojects.
