AWS is totally uncompetitive if your looking to serve video though, Amazon's bandwidth pricing is something straight out of 1999, it is one of the largest pieces of their moat to lock people into AWS.
I'm one of those people the comment above you mentioned who runs a site hosting pirate media (it's all private before anyone asks)
Looked into AWS a while ago so I could throw some encrypted containers on it thinking it would be cheaper. Storage on S3 would have cost about four times as much as I'm paying now in VPS costs, and EFS (the service I actualy wanted) about ten times as much, and that's before looking at bandwidth. Oh and I'd still need at least one VPS to handle transcoding, content delivery etc.
I think Netflix save money by using S3 for the majority of their storage but having their own CDN so they use less bandwidth from AWS.
