title: Disaster Recovery plan with single region deployment
body: <p>One of our customer opt out of multi region deployment of their application due to various reason (assumed calculated SLA for single region is enough for their business need)
  However they asked if there is DRP (Disaster Recovery Plan) available for their application.</p>
  <p>Maybe there could be some missing pieces in my understand on DRP but I just wonder if DRP is still required (or even possible) for the workload that is not provisioned with multi region redundancy.</p>
  <p>Please advise and thank in advance</p>
