> It's about building and maintaining the electrical/cooling/network infrastructure the servers require. Except at the extreme high end of scale, you never do this yourself. Rent racks in a colocation. It's a very clean separation of duties. You handle all the tech work, they handle all the real estate upkeep. > Or you rent a rack in a colo (or five)... But that's just a step away from going full cloud What? Not even close. When you rent a rack in a colo you have 100% of the benefits of owning the hardware (much higher performance, much lower cost). Just because you let someone else do the A/C and generator maintenance (and other non-computer real estate logistics) doesn't make it anything at all like the cloud.
