Modify a scaling group

Last Updated: Sep 25, 2017

You can modify the attributes of a scaling group after it is created.

Note the following attributes cannot be modified:

  • Region
  • Server Load Balancer
  • RDS database instance

This operation can be executed only for scaling groups in active or inactive status.

If the number of ECS instances (Total Capacity) in the scaling group does not meet the new MaxSize or MinSize settings, Auto Scaling adds or removes ECS instances to or from the group until the MaxSize or MinSize value is reached.


  1. On the Scaling Groups page, click Modify next to the scaling group whose settings are to be modified.
  2. On the Modify Scaling Group page, modify the group’s settings as needed.
