title: AWS Is it possible to automatically terminate and recreate new instances for an auto scaling group periodically?
body: <p>We have an AWS scaling group that has 10-20 servers behind a load balancer. After running for a couple of weeks some these server go bad. We have no idea why the servers go bad and it will take some time for us to get to a stage where we can debug this issue.
  <br/>
  <br/>
  In the interim is there a way to tell AWS to terminate all the instances in the scaling group in a controlled fashion (one by one) until all the instances are replaced by new ones every week or so?</p>
