I have had the opportunity to consider from scratch what is needed to migrate applications into the cloud. The first question I usually get asked is with cloud vendor do I recommend Amazon, Azure etc.
My reply is I am not worried about that – and ask if there is a clear strategy to support multi-tenancy for the application being developed for, or ported to the cloud. If not read on for both an introduction, and a checklist of practical steps I recommend.
