# DeleteAutoScalingGroup
<a name="API_DeleteAutoScalingGroup"></a>

Deletes the specified Auto Scaling group.

If the group has instances or scaling activities in progress, you must specify the option to force the deletion in order for it to succeed. The force delete operation will also terminate the EC2 instances. If the group has a warm pool, the force delete option also deletes the warm pool.

To remove instances from the Auto Scaling group before deleting it, call the [DetachInstances](https://docs.amazonaws.cn/autoscaling/ec2/APIReference/API_DetachInstances.html) API with the list of instances and the option to decrement the desired capacity. This ensures that Amazon EC2 Auto Scaling does not launch replacement instances.

To terminate all instances before deleting the Auto Scaling group, call the [UpdateAutoScalingGroup](https://docs.amazonaws.cn/autoscaling/ec2/APIReference/API_UpdateAutoScalingGroup.html) API and set the minimum size and desired capacity of the Auto Scaling group to zero.

If the group has scaling policies, deleting the group deletes the policies, the underlying alarm actions, and any alarm that no longer has an associated action.

For more information, see [Delete your Auto Scaling infrastructure](https://docs.amazonaws.cn/autoscaling/ec2/userguide/as-process-shutdown.html) in the *Amazon EC2 Auto Scaling User Guide*.
