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.
