We are considering using a company called TRAPP Technology to host our Sage 100 Contractor in a cloud environment.  We did a trial run and it performed perfectly with only 2 virtual desktops.  However, it didn't take long to realize that upgrading to the SQL based version 20 presented some interesting challenges.  You can't open the Database Administrator from a remote connection so some important admin functions can't be accessed.  Also, the physical database is hidden in the root partition that is inaccessible with a remote connection.  I was wondering if anyone has found a way to deal with this other than calling the service provider to do it for you.
