 AWS will handle the process of killing the nodes with the old launch configurations and launching new nodes with the latest
 launch configuration. AWS will initially spin up some extra nodes (for around a 60 node cluster it will spin up 8 extra) to provide spaces for pods as old nodes are cordoned, drained and deleted.
