Having worked at AWS for about half a decade in the past, I can guarantee that if you've thought of a way to abuse^W leverage their services for alternative purposes, someone has thought of it internally, as well. I knew someone back in 2014 who was working on a project to build a data store on tags, since tags were free. (The reality is that the tagging infrastructure would never have supported this kind of large-scale use, though. I remember a customer who was applying multiple unique tags to every single EC2 instance they launched, and by the time they had launched hundreds of thousands of instances, they were seeing very real latency when interacting with tags. I think the underlying performance issue was resolved, but these sorts of gotchas are all over the place.)
