What Is Elastic Cloud Server?

What Is Elastic Cloud Server?


An Elastic Cloud Server (ECS) is a computing server consisting of CPUs, memory, and Elastic Volume Service (EVS) disks. ECSs are available on demand and scalable. The ECS service works with the Virtual Private Cloud (VPC) and Cloud Server Backup Service (CSBS) services to build an efficient, reliable, and secure computing environment. This ensures stable and uninterrupted running of your services. The resources, including CPUs and memory, used by ECSs are hardware resources that are consolidated using the virtualization technology.

When creating an ECS, you can customize the number of CPUs, memory size, image type, and login authentication mode. After an ECS is created, you can use it like using your local computer or physical server.


The ECS service allows you to:

  • Customize the flavor, image, network, disks, authentication mode, and number of ECSs when creating ECSs.
  • Expand the capacity of EVS disks attached to an ECS, attach EVS disks to an ECS, detach EVS disks from an ECS, and use shared EVS disks.
  • Change the ECS operating system (OS) and reinstall the ECS OS.
  • Bind an elastic IP address (EIP) to and unbind an EIP from an ECS. This feature is supported only in Type I and Type II scenarios.
  • Manage the life cycle of an ECS, including starting, stopping, restarting, and deleting an ECS.
