Scaling
`StepScalingPolicyConfiguration` is a property of the AWS::ApplicationAutoScaling::ScalingPolicy resource that specifies a step scaling policy configuration for Application Auto Scaling. For more information, see Step scaling policies in the Application Auto Scaling User Guide.
Properties
Specifies whether the `ScalingAdjustment` value in the `StepAdjustment` property is an absolute number or a percentage of the current capacity.
The amount of time, in seconds, to wait for a previous scaling activity to take effect. If not specified, the default value is 300. For more information, see Cooldown period in the Application Auto Scaling User Guide.
The aggregation type for the CloudWatch metrics. Valid values are `Minimum`, `Maximum`, and `Average`. If the aggregation type is null, the value is treated as `Average`.
The minimum value to scale by when the adjustment type is `PercentChangeInCapacity`. For example, suppose that you create a step scaling policy to scale out an Amazon ECS service by 25 percent and you specify a `MinAdjustmentMagnitude` of 2. If the service has 4 tasks and the scaling policy is performed, 25 percent of 4 is 1. However, because you specified a `MinAdjustmentMagnitude` of 2, Application Auto Scaling scales out the service by 2 tasks.
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.
