I'm not sure it has to stay this way though. I think turn-key private cloud is almost within reach. We clearly aren't there now, but it'll come in time.

Get to a certain maturity and standardization of the cloud software. Don't deliver servers, deliver half-racks, pre-assembled, Turn-key. No screwdrivers, no wiring to braid, just a hundred cores on a couple dozen motherboards and a couple 10G wires coming out the side.
