True, but there is with utilization. Most systems are speced for peak
load (or some margin _over_ peak load). So, you can pack more VMs into X
machines, than you could if you used "real" machines.

Well, it depends. I recon we're on the way to "private clouds" where the
cloud is in your data center next to your existing machines, so there
are no additional security implications. Cloud computing isn't just
about running on someone else's hardware -- its more about not caring
what specific machine you execute on, parallel processing, and batch
processing. Yes, it does seem a bit like a mainframe.
