Enable a scaling group

Last Updated: Sep 28, 2017

You can enable a scaling group so that, if the existing number of ECS instances is less than the MinSize value of an enabled (Active) scaling group, Auto Scaling creates Pay-As-You-Go ECS instances until the MinSize value is reached.

For example, if MinSize is set to 5 during the creation of a scaling group, and the group has only 2 ECS instances when enabled, Auto Scaling creates 3 ECS instances to add to the group.

You can only enable inactive scaling groups with active scaling configurations.

A single scaling group can have one active scaling configuration at a time.


On the Scaling Group List page, click Enable next to the scaling group to enable a scaling group.
