What is ECS?

Elastic Compute Service (ECS) is an IaaS offering that provides high-performance, stable, reliable, and scalable computing capacity in the cloud. ECS eliminates your need to invest in hardware upfront. You can create as many or as few instances as you need in response to changes in requirements or the popularity of your workloads. With an ever-growing selection of instance types, ECS provides broader and deeper choices to match a wide spectrum of computing needs.
