Key Operations on EVS

Elastic Volume Service (EVS) is a scalable virtual block storage service that is based on the distributed architecture. EVS disks can be operated online. Using them is similar to using common server hard disks. Compared with common server hard disks, EVS disks have higher data reliability and I/O throughput capabilities. They are also easier to use. EVS disks apply to file systems, databases, or system software or other applications that require block storage devices.

With CTS, you can record operations associated with EVS for later query, audit, and backtrack operations.
