AWS Aurora PostgreSQL is built on a distributed storage system that automatically scales up to 128 TiB and replicates data across multiple Availability Zones.

You can pay for AWS Aurora PostgreSQL using On-Demand or Reserved Instances. On-Demand Instances let you pay by the hour with no long-term commitments, while Reserved Instances offer significant discounts for one or three year terms.
