Amazon Relational Database Service (RDS) vs. EDB Postgres Advanced Server

Amazon Relational Database Service (Amazon RDS) makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity while managing time-consuming database administration tasks such as hardware provisioning, database setup, patching and backups. It frees you up to focus on your apps so you can give them the better performance, availability, security, and compatibility they need. Amazon RDS is available on 6 familiar database instances: Amazon Aurora, MySQL, PostgreSQL, MariaDB, Oracle Database and SQL Server engines.

EDB Postgres Advanced Server (EPAS) is based on open source PostgreSQL, the world's most advanced open-source database management system. EPAS gives you the best of both worlds - all the advantages of PostgreSQL, enhanced with mission-critical features that help you maintain greater consistency across your PostgreSQL deployments. EDB Postgres Advanced Server extends PostgreSQL with the security and performance features that enterprises need. It is also Oracle compatible.
