| Feature | Description |
|---|---|
| Support for detaching instances from an Auto Scaling group. | You can now detach instances from a group. You can manage detached instances directly or move them to another Auto Scaling group. Detached instances do not count toward the desired capacity of the Auto Scaling group and are excluded from Auto Scaling CloudWatch metrics. For more information, see Detach Amazon EC2 Instances From Your Auto Scaling Group. |
| Support for putting instances into a Standby state. | You can now put Auto Scaling group instances into a Standby state. This state is available only for instances that are currently in service. (You can't put instances that are launching or terminating into a Standby state.) This state can help you perform tasks such as installing software updates or troubleshooting. You have the option of deciding if you want instances in a Standby state to count toward the desired capacity of the Auto Scaling group. For more information, see Auto Scaling InService State. |
| Support for adding lifecycle hooks to Auto Scaling groups. | You can now add lifecycle hooks to Auto Scaling groups. You can use these lifecycle hooks to control instances as they launch or as they terminate. For example, you can use hooks for instances that require manual software configurations, or to retrieve log files before the instance terminates. For more information, see Auto Scaling Lifecycle Hooks, Auto Scaling Pending State, and Auto Scaling Terminating State. |
