General-Purpose ECSs

Overview

General-purpose ECSs provide a baseline level of CPU performance with the ability to burst above the baseline and a balance of computing, memory, and network resources. These ECSs are suitable for many applications, such as web servers, enterprise R&D, and small-scale databases.

Scenarios

  • Applications

    General-purpose ECSs are suitable for applications that have no special requirements on CPU performance, memory, disk capacity, or bandwidth, but have high requirements on security and reliability. They feature low initial investment and maintenance costs.

  • Application scenarios

    Enterprise website deployment, enterprise office environment setup, enterprise R&D and testing activities, Web servers, R&D and testing environments for developers, and small-scale databases
