The ability to have more than one server in each region is great for redundancy purposes as well being able of having different versions (or branches) at same time without impacting performance too much! As I said before it's not so easy if you're using only 1 version per branch but this could be solved by adding an option where we can choose which environment will use when deploying our code from git repository into production servers; also there are some minor issues with deployment process that should get fixed soonly like automatic deploys after successful tests etc..
