Using termination protection

It goes without saying that one should not keep state on machines if it can be helped.

After all, the beauty of AWS is that it allows you to not focus so much on individual instances any more. It promotes a cluster or service culture where the health of the endpoint is of importance.

For the rare cases where we must have one of those management or similar type of non-autoscaling node, however, you have nothing but to gain from protecting yourself against accidentally making the wrong API call or a console click.
