There's no way to verify that this truck full of my corp's valuable data isn't stopped somewhere along the way and cloned and then driven to NSA or something.
You're putting it in the truck with the intention of shipping it to Amazon to load it onto their infrastructure. If you don't trust Amazon with your data, the truck isn't unique in any way...they can clone your data at their data center too.
Well that's what I'm saying. I mean I guess that rabbit hole goes all the way, even if Amazon brought their machines to me, there's still not a guarantee that it won't be stolen somehow.
