Another Misapplication of Cloud Tech
I can't see how this could be cheaper than doing things with Delta's own, in-house computers. Their workloads aren't fluctuating that much, they won't need to suddenly scale up to a gazillion processors, and all that analytics could be done on their in-house computers. Further, they'll have more external dependencies, and if things go wrong at Amazon, Delta is (and/or their customers are) hosed, and there's nothing the Delta techs can do about it.
But hey, the Board of Directors can brag to their cronies that Delta's computer systems are buzzword-compliant.
