It is fairly common now for big companies (Oracle comes to mind) to
set up remote data centers for employee systems. When I worked at
Oracle I never really saw my primary Linux machine. I believe these
machines were not virtual machines, but real ones. So the move to
virtualization should make this a true cloud computing solution.
Likewise Citrix, my current employer, hosts all applications that employees
use "out there". Of course, that's what Citrix does well.
HR applications, IT resources etc. are but internal websites that
employees have gone to for years now.
Lastly storage has lived on the SAN for some time now.
