Update an Auto Scaling group

To update an Auto Scaling group (console)

1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/, and choose Auto Scaling Groups from the navigation pane.

2. Choose your Auto Scaling group to display information about the group, with tabs for Details, Activity, Automatic scaling, Instance management, Monitoring, and Instance refresh.

3. Choose the tabs for the configuration areas that you're interested in and update the settings as needed. For each setting that you edit, choose Update to save your changes to the Auto Scaling group's configuration.

   • Details tab

     These are the general settings for your Auto Scaling group. You can edit and manage these in the same way as during Auto Scaling group creation.

     The Advanced configurations section has some options that are not available when creating the group such as termination policies, cooldown, suspended processes, and maximum instance lifetime. You can also view, but not edit the placement group and service-linked role of the Auto Scaling group.

     If the group is associated with Elastic Load Balancing resources, see Add an Availability Zone before changing Availability Zones. Some restrictions on the load balancer might prevent you from applying changes to your group's Availability Zones to your load balancer's Availability Zones.
