One hard problem here though, by the looks of it, the tool is a database designed by engineers in response to a lengthy requirements document. It has no regard for user experience, and is one of those things you can use, only if you go through a 3 week training course.
This, imo, is where AWS could borrow from startup playbook, and instead of launching a spaceship, start instead with a paper airplane. Imagine if all you could do was to publish an inventory-management tool, that in one-click integrated with Amazon Pay and let the customers buy your products on a website?
Maybe Amazon is waiting for someone else to build this on top of their tools, and then make it available, but that poses a question why. Why would someone build on top of Honeycode, only to have Amazon eventually make it their own?
Interesting concept, but it's got a long ways to go before anyone needs to be scared of what Amazon can do with this thing.
