This has a few big improvements over Aurora. Aurora has scaleable disk, but is still 1 big master Postgres instance (and optional read replicas), with all the drawbacks that comes with in scaling speed, cost and failure modes. This appears to be a distributed many-peer-node Postgres, with an all new abstracted distributed storage layer. This allows a lot of neat things with scaling/cost, and innovation on the storage layer (like their writeout to S3). Basically this is true serverless postgres if the claims are correct, and that's amazing.
