S3 is flexible and scalable, but it is not cheap. I'd be hard pressed to run the numbers now, but at some point it's cheaper to just do storage yourself. But to be fair, you'll go on-premise due to the computing or bandwidth costs first. And you'll likely move data to the same datacenter to avoid expensive transfer costs. I've also had to work in places where you simply could not put your data in the cloud due to regulatory reasons.
