&quot;Loaded TCO&quot; means gear, space, power, cooling, transit, people...  Those are high-level, and I don&#x27;t remember a bunch of things that went into the 5-year TCO model but it was complex.<p>If you have the talent and scale it&#x27;s certainly doable, and like I said, we were at less than half of AWS.  There are plenty of examples, one that comes to mind that is NOT hyper-scale is Server Fault.
