I used BIMserver on Amazon ESW. It works very good.
What is important - you need to hire a machine with Windows Server or MacOS operative system with enough RAM and disk space. Better to have minimum double core processor 2.5 GHz.
After you are logging in into your server using remote computer function and installing BIM server as it would be any software. Important is to open ports in Firewall settings (not in Firewall of operative system, but firewall of the service).
You also can install apache on the server and run your web-site from the same machine as BIMcloud.
