General-Purpose ECSs

Overview

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

S6 ECSs are suitable for applications that require moderate performance generally but occasionally burstable high performance, such as light-workload web servers, enterprise R&D and testing environments, and low- and medium-performance databases. S6 ECS performance is neither restricted by vCPU credits nor billed for additional credits. You can determine the CPU usage and vCPU credits in monitoring details.
