You could own hardware and do this but that isnt what I’m going to be talking about because you know that would be more like a dedicated server that was discussed, but at the same time some of the benefits of virtualization, and not that it would be considered cheating, because it isnt, but it would bring up a whole other set of pros and cons that I couldnt find space to talk about.
