Virtualization ‘breaks’ (or at least fundamentally changes) a great number of the operating assumptions that IT organizations have come to consider as normal.

For instance: In the past, the System Administrators were responsible for the boxes, and the applications and operating systems that ran on them. Network Administrators were responsible for the switches and the wires, and the Storage Admins owned the enterprise spindles, the fibre, and the tape (backups).

That was until recently.
