Elastic Cloud Server Video

An Elastic Cloud Server (ECS) is a scalable, on-demand computing server that consists of CPUs, memory, and disks. ECS works with other services such as Virtual Private Cloud (VPC) and backup services to provide a secure and efficient computing environment, ensuring reliable and uninterrupted services.

Stability and Reliability

If a host fault occurs, the ECSs on the host are automatically migrated to a functional host, ensuring 99.95% service availability. Multiple copies of your data ensures 99.99999% data persistence. ECSs and EVS disks can be backed up and restored.


The network of your ECS is completely isolated. Security group rules protect the network from viruses and Trojans. Multi-dimensional security protection mechanisms are at no additional charge.

Competitive Advantage
