My (late) point is that when people speak about "on-prem" these days, they are not talking about building corporate datacenters on campus. 30 years ago when you talked on-prem that's what this meant. It's now shifted to on-prem meaning your own hardware in massive shared facilities that handle all that "hard stuff" like redundant power and cooling for you. Bespoke datacenter builds for true-on prem certainly exist, but it's not what that term typically means any longer - at least in my line of business. When I'm selling racks of colo now, my customers are calling that their on-prem facilities. In fact a large part of my previous business was dismantling true "on-prem" facilities to move to such large shared wholesalers.
