We do something called Virtualization :
In its simplest form we can allow a company to save substantial amounts of money by consolidating many physical servers (or PCs) onto one physical box.
Take a large FTSE100 company they may have 1000+ physical servers stored in a large air conditioned room, there are large costs invloved in owning 1000+ servers and their associated cooling and power requirements. Our software allows a company with a 1000 servers to reduce this amount by 90%, so to say 100 Servers. Everything runs as before but crucially they can now make massive savings on space, cooling, power etc and the guys in IT who are supporting all this equipment now find it easier to do their job.
Another example, you are probably running Windows XP on your PC, what if you decided you wanted to try Linux or Windows Vista or Unbuntu or some other Operating System ? You can install some of our software and we will allow you to run a another operating system on your existing Windows XP machine.
Hope this helps ? The company is probably one of the largest you have never heard of, current Market cap is $40B +
