>We've gone from big honkin' iron in the closet, to mini silicon under the desk to big honkin' iron in the cloud, which could be another room in the building. It's not that hard of a concept
Except once upon a time you paid $$$ for the big iron if you used it or not, $$$ for the OS licence, $$$ for the room it went in and $$$ for the AC/Power/maintenance etc
If mainframe companies offered to install almost unlimited capacity, manage the real estate and HVAC but only charged you for what you used - there might be more of them still in business.
Even back in the 2000s we had to guess how many customers we would have for the next quarter and try and buy/install enough Suns and cram in enough racks to keep ahead of demand, without running out of money. Being able to scale a data center from a keyboard minute-minute is very nice.
