You will set up Auto Scaling for the Spot fleet to scale up and down as demand increases and decreases. For long-term stability of core capacity, you will also add a small group of on-demand EC2 instances to the cluster. At the end of this lab you will have an ECS cluster composed of Spot fleet instances with Auto Scaling enabled, and an on-demand instance from an Auto Scaling group.
