ManagedScaling
The managed scaling settings for the Auto Scaling group capacity provider.
When managed scaling is turned on, Amazon ECS manages the scale-in and scale-out actions of the Auto Scaling group. Amazon ECS manages a target tracking scaling policy using an Amazon ECS managed CloudWatch metric with the specified targetCapacity value as the target value for the metric. For more information, see Using managed scaling in the Amazon Elastic Container Service Developer Guide.
If managed scaling is off, the user must manage the scaling of the Auto Scaling group.

Determines whether to use managed scaling for the capacity provider.
The target capacity utilization as a percentage for the capacity provider. The specified value must be greater than 0 and less than or equal to 100. For example, if you want the capacity provider to maintain 10% spare capacity, then that means the utilization is 90%, so use a targetCapacity of 90. The default value of 100 percent results in the Amazon EC2 instances in your Auto Scaling group being completely used.
