My point is, you don't need an expensive global CDN if your end goal is to optimize for ad-revenue within the U.S market. I don't know why you stuck on the CDN, and it sounds like you are using it as a hammer to achieve scalability.

I'm stuck on the CDN because you need something like a CDN to serve any meaningful number of concurrents. The numbers I quoted for cloudfront were for the US.

If you believe otherwise, please enlighten me on how you can build a HD video streaming service for 100 concurrents without a CDN. Like I mentioned, on a 1GbE connection, you can serve a theoretical max of 45 users on one node. Where do you go from there without something that looks like CDN?
