General Computing ECSs

Overview

General computing 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 general workloads, such as web servers, enterprise R&D, and small-scale databases.

Hyper-threading is enabled for this type of ECSs by default. Each vCPU is a thread of a CPU core.

Available now: X1, S7, S7n, S6, Sn3, S3, and S2
