As you build your business you can purchase one of their sedmi-dedicated servers for around $35/month. This feature limits the number of users on one box and is a good alternative to a dedicated server.

They’ve also made a few changes to the specs from when I first looked at them, they now allow multiple domains from your account — a bonus!
