For which type of web sites would this make a difference? I think for this to matter, the audience should be almost global, in which case it will cater to a small percentage. Some examples: - News sites: These heavily use CDN's and caching, wouldn't make much difference. - Most CRUD apps which target a small number of users? Probably no significant difference being on the edge would bring. - Games: this is one area this might make a difference due to latency advantage. Could someone give some real examples from the net that would make switching to this edge architecture a difference? For example, something like, it would be good if HackerNews/CNN/Intuit did this so that...?
