>AWS is streaming video, operating hundreds of edge location CDN locations, and everything else running on expensive server infrastructure. AWS has real serious costs with offering that service, to the point that Netflix has yet to determine that it is better to build it themselves.
Somewhat off the core topic, but netflix run their own CDN (I also don't see any evidence for that 1.2 billion AWS bill figure, can you provide a link? Their latest SEC filing doesn't separate cloud service costs from the running of their Open Connect CDN)
