Before You Start
Welcome to use Cloud Certificate Manager (CCM). Cloud Certificate Manager (CCM) issues cloud certificates and manages the entire lifecycle of the certificates. It can be used in many scenarios, such as cloud platform, Internet of Vehicles (IoV), and Internet of Things (IoT). CCM includes the SSL Certificate Manager (SCM) and Private Certificate Authority (PCA) services.
Before calling CCM APIs, ensure that you have understood the concepts related to CCM. For more information, see What Is CCM?
Endpoints
An endpoint is the request address for calling an API. CCM is a global service deployed for all physical regions. Table 1 lists all CCM endpoints. You can obtain CCM endpoints at Regions and Endpoints.
Concepts
- Account
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. An account is a payment entity. Accounts should not be used directly to perform routine management. For security purposes, create sub-users and grant them permissions for routine management.
- 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).
An IAM user can view the account ID and user ID on the page of the console. The domain name, username, and password will be required for API authentication.
- Region
Regions are divided based on 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 as universal regions and dedicated regions. A universal region provides universal cloud services for common tenants. A dedicated region provides services of the same type only or for specific tenants.
- Availability Zone (AZ)
An Availability Zone (AZ) contains one or more physical data centers. Each AZ has independent cooling, fire extinguishing, moisture-proof, and electricity facilities. Within an AZ, compute, network, storage, and other resources 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.
- 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 create resources in the subprojects. Users can then be assigned permissions to access only specific resources in the subprojects.
Figure 1 Project isolating model - Enterprise Project
Enterprise projects group and logically isolate resources. An enterprise project can contain resources in multiple regions, and resources can be directly transferred between enterprise projects.
For details about how to obtain enterprise project IDs and features, see Enterprise Management User Guide.
