Production Servers

When it comes time to publish the license servers to a cloud space will we have to build each release of our games to an individual DNS name?  Replacing local host "Master Server"  with said DNS name?  Do I understand it correctly that it is $400 per 1000 users?  Is there a good tutorial on building out your first 1000 users in a cloud space from the Atavism side.  I dont need information on build the servers or cloud just server side Atavism license side.  And is there a server side size for each server that is recommended per 100 users to 1k users?    Does this just end up being a license server and most of the pressure is on the individual pc for processing as it is in testing?
