Before You Start

COC is a secure and efficient O&M platform, offering one-stop, AI-powered solutions for all your centralized O&M needs. It encompasses Huawei Cloud deterministic operations scenarios and features essential functionalities such as change management, batch O&M, and chaos drills, to improve cloud O&M efficiency while ensuring security compliance.

COC provides the following functions:

O&M situation awareness dashboard is the dedicated O&M BI dashboard for different O&M roles to help management in insight decision-making and optimization.
Full-lifecycle resource management is available. It includes O&M operations such as resource definition, request, provisioning, O&M, configuration change, renewal, and recycling; building a resource management cockpit.
Change risk control and job trustworthiness are available. The management and control model of best practices of Huawei SRE in secure production helps you achieve trustworthy, stable, and reliable O&M experience.
Standardized fault management and war room cockpit achieve efficient fault collaboration and quick fault rectification.
Intelligent chaos drills provide full-stack chaos engineering solutions, transforming traditional passive O&M to proactive O&M.

API Calling

COC provides Representational State Transfer (REST) APIs, and allows you to make API calls over HTTPS.

VPC Endpoint

An endpoint is the request address for calling an API. Endpoints vary according to services and regions. For the endpoints of all services, see Regions and Endpoints.

Restrictions and Limitations

For more constraints, see API.

Concepts

Account
An account is created upon successful signing up. 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, which should not be used directly to perform routine management. For security purposes, create Identity and Access Management (IAM) users and grant them permissions for routine management.
User
An IAM user is created by an account in IAM to use cloud services. Each IAM user has its own identity credentials (password and access keys).

API authentication requires information such as the account name, username, and password.
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 into universal regions and dedicated regions. A universal region provides universal cloud services for common tenants. A dedicated region provides specific services for specific tenants.

For details, see Region and AZ.
AZ
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.
Project
A project corresponds to a region. Default projects are defined to group and physically isolate resources (including computing, storage, and network resources) across regions. Users can be granted permissions in a default project to access all resources under their accounts in the region associated with the project. If you need more refined access control, create subprojects under a default project and create resources in subprojects. Then you can assign users the permissions required to access only the resources in the specific subprojects.

Figure 1 Project isolation model
Enterprise Project
Enterprise projects group and manage resources across regions. Resources in different enterprise projects are logically isolated. An enterprise project can contain resources of multiple regions, and resources can be added to or removed from enterprise projects.

For details about enterprise projects and about how to obtain enterprise project IDs, see Enterprise Management User Guide.
