Are the ebs volumes used by the instances launched by an autoscaling group deleted when the instances are replaced/terminated?

I have an auto-scaling group with 2 instances.

Every time an instance is launched an EBS volume is attached to it. When it is replaced/terminated is the EBS volume deleted ?

I want to keep a tight budget on my account and I dont want to have volumes lingering and pay for them.

Solution

You can configure it both ways. If you are using the web interface to configure the launch configuration when you get to Storage you will see this:

You just need to check the "Delete on Termination" checkbox on the right, whenever an instance is terminated the EBS volume associated will be deleted as well.
