ScalingGroup

This class encapsulates and extends the ROS resource type ALIYUN::ESS::ScalingGroup, which is used to create a scaling group.

A scaling group is a group of Elastic Compute Service (ECS) instances that are dynamically scaled based on the configured scenario. A scaling group does not immediately take effect after it is created. You must use ALIYUN::ESS::ScalingGroupEnable to enable the scaling group to trigger scaling activities and execute scaling rules.
