I think you're being a bit too literal here. Did AWS merely fork the infrastructure that Amazon.com runs on and start selling it, no. But are you telling me that it wasn't built on the lessons learned of amazon.com and that it doesn't share some aspects of how amazon.com worked a the time (with improvements to the bad parts)? I don't know the answer and maybe it was a clean-room implementation but that seems unlikely to me.
