Autoscaling policies define the criteria that trigger autoscaling actions and the actions to take.
An autoscaling policy is part of an autoscaling configuration. For more information, see Autoscaling.
You can create the following types of autoscaling policies:
Schedule-based: Autoscaling events take place at the specific times that you schedule. - Threshold-based: An autoscaling action is triggered when a performance metric meets or exceeds a threshold.
