It looks like they are trying to use the same model as http://wable.com/.

They sell you a monthly subscription to a resource bundle (some # of cpus, ram, disk space, ipv4s) that you can then run as 1 large VPS, or 3 medium ones, or 4 smalls + 1 medium, etc.

Wable is fairly popular because of this approach, and they are relatively unique in doing it that way.
