Before deploying, consider using our new offering, Databases for PostgreSQL. PostgreSQL is a powerful, open source object-relational database that is highly customizable. It's a feature-rich enterprise database with JSON support, giving you the best of both the SQL and NoSQL worlds. Pricing is based on underlying disk usage. CPU & I/O resources scale with the underlying disk usage. IBM Compose for PostgreSQL makes PostgreSQL even better by managing it for you. Features include auto-scaling deployments, high availability, and automated no-stop backups.
