Not quite. Aurora serverless spins up machines for requests and spins them down. If I were paying just for storage and IOs, it'd be perfect. But I'm paying for ACU-hours. There is a 10 minute minimum charge, and an unknown ramp-up time if there are no ACUs spun up. If I have a web app which is accessed once every 10 minutes (0.002 requests per second), I'll be paying for a full AWS machine. It should be a shared, scalable resource and abstraction.
