When using autoscaling you can protect instances from termination during scale in events by selecting them in the Auto Scaling Console and then choosing Instance Protection from the Actions menu.

You might want to do this for several reasons. First, an instance might be handling a long-running work task, perhaps pulled from an SQS queue. Protecting the instance from termination will avoid wasted work. Second, the instance might serve a special purpose within the group. It could be the master node of a Hadoop cluster or a “canary” that flags the entire group of instances as up and running.

In most cases, you will want to leave at least one instance in each of your auto scaling groups unprotected. If all of the instances are protected, no scale in action will be taken.
