Represents a step scaling policy configuration to use with Application Auto Scaling.
public class StepScalingPolicyConfiguration
The StepScalingPolicyConfiguration type exposes the following members
Gets and sets the property AdjustmentType.
Specifies whether the
Gets and sets the property Cooldown.
The amount of time, in seconds, after a scaling activity completes where previous trigger-related scaling activities can influence future scaling events.
For scale-out policies, while the cooldown period is in effect, the capacity that has been added by the previous scale-out event that initiated the cooldown is calculated as part of the desired capacity for the next scale out. 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 cooldown period of 5 minutes starts. During the cooldown 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.
For scale-in policies, the cooldown 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 cooldown period after a scale-in, Application Auto Scaling scales out your scalable target immediately.
Gets and sets the property MetricAggregationType.
The aggregation type for the CloudWatch metrics. Valid values are
Gets and sets the property MinAdjustmentMagnitude.
The minimum number to adjust your scalable dimension as a result of a scaling activity.
If the adjustment type is
For example, suppose that you create a step scaling policy to scale out an Amazon
ECS service by 25 percent and you specify a
Gets and sets the property StepAdjustments.
A set of adjustments that enable you to scale based on the size of the alarm breach.
