An ECS is a computing server that consists of CPUs, memory, images, and EVS disks and allows on-demand allocation and elastic scaling. The ECS service integrates VPC, virtual firewall, and multi-data-copy capabilities to create an efficient, reliable, and secure computing environment for users to ensure stable and continuous service running. After creating an ECS, users can use it like using their local computer or physical server.
ECSs support self-service creation, modification, and operation. Users can create an ECS by specifying its CPU, memory, image specifications, and login authentication mode. After creating an ECS, users can modify its specifications as required.
