What Is ECS?

An Elastic Cloud Server (ECS) is a basic computing unit that consists of vCPUs, memory, OS, and Elastic Volume Service (EVS) disks. After an ECS is created, you can use it on the cloud similarly to how you would use your local PC or physical server.

ECSs support self-service creation, modification, and operation. You can create an ECS by specifying its vCPUs, memory, OS, and login mode. After an ECS is created, you can modify its specifications if necessary. ECS works with other services to provide a reliable, secure, efficient computing environment.

System Architecture

ECS works with other products and services to provide computing, storage, and network resources. You can quickly migrate and replicate existing ECSs using images.

Access Methods

The public cloud provides a web-based service management platform. You can access ECSs through HTTPS-compliant application programming interfaces (APIs) or the management console.
  • Accessing ECSs through APIs

    Use this method if you are required to integrate the ECSs on the public cloud platform into a third-party system for secondary development. For detailed operations, see Elastic Cloud Server API Reference.

  • Accessing ECSs through the management console

    Use this method if you are not required to integrate ECSs with a third-party system.

    After registering on the public cloud platform, log in to the management console and click Elastic Cloud Server under Compute on the homepage.
