During a scaling activity, when Auto Scaling fails to add ECS instances into a scaling group, it will try to ensure transaction completeness and roll back the scaling activity.
For example, a scaling activity intends to create and add 20 ECS instances into the scaling group, but only 19 of them are added successfully. In this case, the entire scaling activity will be rolled back, and the 19 instances will be removed and released as well.
