What is Cloud server ECS

Cloud Server ECS (Elastic Compute Service) is a computing service that is resilient and scalable, and is managed in a simpler and more efficient manner than a physical server. Without advance purchase inputs, you can create instances, expand Disks, or free multiple instances of cloud servers, depending on your business needs.

The Cloud Server ECS instance (ECS instance) is a virtual computing environment, which contains the most basic computing components, such as CPU and memory, and is the actual operation entity presented to each user by the cloud server. ECS instance is the core concept of cloud server, and other resources, such as disk, IP, mirror, snapshot and so on, can only be used when combined with ECS instance.

The following figure is a schematic diagram of the cloud server ECS instance. You can configure your ECS instances through the Cloud Server Management console, such as selecting the instance specification, disk, operating system, bandwidth, and security group resources.
