@Generated("software.amazon.awssdk:codegen")
public final class ScalingRule
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<ScalingRule.Builder,ScalingRule>

A scale-in or scale-out rule that defines scaling activity, including the CloudWatch metric alarm that triggers activity, how Amazon EC2 instances are added or removed, and the periodicity of adjustments. The automatic scaling policy for an instance group can comprise one or more automatic scaling rules.
