Concepts

An account is created upon successful registration. 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.

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.

Regions are divided from the dimensions of geographical location and network latency. Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP (EIP), and Image Management Service (IMS), are shared within 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.

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.

A project is created by a user in CodeArts Req based on a template. It also contains preset work items, code, and resources. Identity and Access Management (IAM) users in a project are added to the project as team members with corresponding roles and permissions.

A template-based project is created with a preset template. That is, Scrum or Kanban work items and processes preset in CodeArts Req. You can select a project template or create a development task.

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.
