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, to wait for a previous scaling activity to take effect.
With scale-out policies, the intention is to continuously (but not excessively) scale out. After Application Auto Scaling successfully scales out using a step scaling policy, it starts to calculate the cooldown time. While the cooldown period is in effect, capacity added by the initiating scale-out activity is calculated as part of the desired capacity for the next scale-out activity. For example, when an alarm triggers a step scaling policy to increase the capacity by 2, the scaling activity completes successfully, and a cooldown period starts. If the alarm triggers again during the cooldown period but at a more aggressive step adjustment of 3, the previous increase of 2 is considered part of the current capacity. Therefore, only 1 is added to the capacity.
With scale-in policies, the intention is to scale in conservatively to protect your application’s availability, so scale-in activities are blocked until the cooldown period has expired. However, if another alarm triggers a scale-out activity during the cooldown period after a scale-in activity, Application Auto Scaling scales out the target immediately. In this case, the cooldown period for the scale-in activity stops and doesn't complete.
Application Auto Scaling provides a default value of 300 for the following scalable targets:
For all other scalable targets, the default value is 0:
Gets and sets the property MetricAggregationType.
The aggregation type for the CloudWatch metrics. Valid values are
Gets and sets the property MinAdjustmentMagnitude.
The minimum value to scale by when scaling by percentages. For example, suppose that
you create a step scaling policy to scale out an Amazon ECS service by 25 percent
and you specify a
Valid only if the adjustment type is
Gets and sets the property StepAdjustments.
A set of adjustments that enable you to scale based on the size of the alarm breach.
At least one step adjustment is required if you are adding a new step scaling policy configuration.
