David, The simple solution if you have an existing Virtual Machine infrastructure is to put the Ambari-Server on a VM with HA that can be restarted automatically in the event of a hardware failure. This usually works best if you move the database to some type of highly available cluster mysql, postgres or oracle rac too.
