It makes perfect sense: it's a extremely reliable, infinitely-scalable, strongly consistent (in some implementation), cheap, and extremely simple to use key-value store. As such, it transparently solves a lot of the problems distributed systems have to be engineered around.
As long as you can run on a CSP, and can engineer around the high-ish latency (most business cases can), it's extremely expensive to try engineer around it.
