Before You Start

Welcome to the DataArts Fabric service. You can use the DataArts Fabric console or application programming interfaces (APIs) to implement services such as foundation model inference and Ray jobs.

This document describes how to use APIs to perform operations, such as creating and deleting inference jobs or job endpoints, on the DataArts Fabric. For more operations, see API Overview.

Endpoints

An endpoint is the request address for calling an API. Endpoints vary depending on services and regions. For the endpoints of all services, see Regions and Endpoints. Select the endpoint of the region based on your service requirements.

Basic Concepts

  • Account

    An account is created upon successful registration with the Huawei 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. For security purposes, do not use the account to perform routine management. Instead, create Identity and Access Management (IAM) users 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).

    For details about the account ID and IAM user ID, see My Credentials. They are 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 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.

  • Availability Zone (AZ)

    An AZ contains one or more physical data centers. Each AZ has independent cooling, fire-extinguishing, moisture-proof, and electricity facilities. Computing, network, storage, and other resources in an AZ are logically divided into clusters. AZs within a region are interconnected using high-speed optical fibers to support cross-AZ high-availability systems.

  • Project

    Each Huawei Cloud region corresponds to a default project. These default projects isolate computing, storage, and network resources across physical regions. By default, users are granted permissions to access all resources in a default project. For more refined access control, you can create subprojects under a default project, purchase resources for the subprojects, and grant users permissions to access resources in specified subprojects. For details about how to obtain the project ID, see My Credentials.

  • Enterprise Project

    Enterprise projects, different from projects, are used to logically isolate resources of different projects in an enterprise. An enterprise project can contain resources from different regions, and resources can be transferred between enterprise projects.

    For more information about enterprise projects, see Enterprise Project Management Service.
