The PostgreSQL-compatible edition of Aurora Serverless is now generally available, allowing users to create database instances that operate only when necessary and automatically adjust capacity based on demand. Customers are billed on a per-second basis for active database capacity and standard Aurora storage costs. Users can specify minimum and maximum capacity when creating a database, and the architecture separates storage from computational resources, allowing automatic scaling from a minimum of 10GB to a maximum of 64 TB. Aurora Serverless PostgreSQL is accessible in regions including US East (N. Virginia and Ohio), US West (Oregon), EU (Ireland), and Asia Pacific (Tokyo).
