The intention is to continuously (but not excessively) scale out. For example, an alarm triggers a step scaling policy to scale out an Amazon ECS service by 2 tasks, the scaling activity completes successfully, and a <code>Cooldown</code> period of 5 minutes starts. During the <code>Cooldown</code> period, if the alarm triggers the same policy again but at a more aggressive step adjustment to scale out the service by 3 tasks, the 2 tasks that were added in the previous scale out event are considered part of that capacity and only 1 additional task is added to the desired count.</p> <p>For scale in policies, the <code>Cooldown</code> period is used to block subsequent scale in requests until it has expired. The intention is to scale in conservatively to protect your application's availability. However, if another alarm triggers a scale out policy during the <code>Cooldown</code> period after a scale-in, Application Auto Scaling scales out your scalable target immediately.</p>"
