I'm quite interested in this, although I'm currently looking for a Windows VPS.
May I ask why your business (or most that I've seen) runs Ubuntu instead of Windows? Is it because Ubuntu is a free OS? If so, couldn't you simply purchase a Windows 7 business license?
As far as I know, it's not exclusive to just the OS' provided - a custom one can be installed upon request. It's just that the provided ones are much quicker to install =P
As to Windows VPS', I think one of the other customers has one as well, so I assume that mrgasp would be willing to install another one to fit your needs.
Be sure to, when you visit to IRC, just ask your questions, and stay tuned for a reply (better way would be to provide contact information, however). MrGaSp would most likely see it within a few hours, or else I or Diab1o could pass it on.
Sorry I missed you on IRC, I was out for a while.
The server doesn't have the video rendering capacity to host many Windows Operating systems. The one i have hosted has had many many strange issues, random lock ups, services not starting, etc, the client is happy with that though.. So i run it.
I could perchance a license, but i simply do not have the money for it. VPS Squared runs one server, and about 5 VPSs as of now, there's not much activity. I do it mostly for the fun, while paying for power and possible upgrades and what not.
Windows requires, generally, Remote Desktop, thus needing a UI, and then needing the server to render the video, sure one screen wont take long, but several adds to the cost. I've learned that running a VPS with a video card, reduces the speed drastically, most of the cycles are spent on rendering and what not..
The one VPS that runs windows server 2008, pays more than a comparable linux.
Clarify on bravetheheat's message, yes it is faster to use preloaded operating systems, just as fast as a copy of a 2GB file. I will install most other linux operating systems without hesitation though. Just give me some extra lead time, installing one takes a bit, getting faster at it after deciding to do it completely in RAM.
