Is twitch using Amazon for streaming video content? I wasn't aware that it was cost efficient to deliver "free" video streams using AWS.
Granted, that article is old, but I think a pretty serious investment in physical infrastructure has been made by Justin.tv/Twitch. So I'm more willing to believe they're still leveraging some variation of this architecture rather than AWS.
