Verify that your ECS service is scaled up on increased CPU usage.

Motivation

Important ECS services should be scaled up within a reasonable time for an elastic and resilient cloud infrastructure. Undetected high CPU spikes and long startup times are undesirable in these infrastructures.

Structure

First, we ensure that all ECS service's tasks are ready to serve traffic. Afterward, we inject high CPU usage into the ECS task and expect that within a reasonable amount of time, ECS increases the number of ECS tasks and they become ready to handle incoming traffic.
