An anonymous reader writes: Amazon Web Services has cut its prices on 40-plus consecutive occasions, at times leading the charge, at other times countering similar moves by Microsoft and Google. This article at CRN includes some interesting behind-the-scenes trivia about how Amazon keeps costs down, including some interesting speculation — for example, that perhaps the reason Amazon's Glacier storage is so cheap is that maybe it might be based at least partly on tape, not disk (Amazon would not comment). The article also explains that the company will only pay for its employees to fly Economy, and that includes its senior executives. If they feel the need to upgrade to Business or First Class, they must do so from their own pocket. And instead of buying hardware from an OEM vendor, AWS sources its own components – everything from processors to disk drives to memory and network cards — and uses contract manufacturing to put together its machines.
