Automatically manage Amazon ECS capacity with cluster auto scaling
Amazon ECS can manage the scaling of Amazon EC2 instances that are registered to your cluster. This is referred to as Amazon ECS cluster auto scaling. You turn on managed scaling when you create the Amazon ECS Auto Scaling group capacity provider. Then, you set a target percentage (the targetCapacity) for the instance utilization in this Auto Scaling group. Amazon ECS creates two custom CloudWatch metrics and a target tracking scaling policy for your Auto Scaling group. Amazon ECS then manages the scale-in and scale-out actions based on the resource utilization that your tasks use.
For each Auto Scaling group capacity provider that's associated with a cluster, Amazon ECS creates and manages the following resources:
A low metric value CloudWatch alarm
A high metric value CloudWatch alarm
A target tracking scaling policy
