Amazon Relational Database Service (Amazon RDS)

Amazon RDS is a Software as a Service (SaaS) that provides a full featured relational database service similar to MySQL & Oracle and hosted entirely on the Amazon infrastructure. Amazon RDS, designed to operate with all AWS cloud products, is based on the conventional cloud utility computing model, where users are only billed for the number of used RDS hours.

By giving access to the functionality of well-known Oracle or MySQL databases, Amazon RDS provides compatibility with many applications and tools familiar to developers. Amazon RDS also helps users scale database instance storage capacity and processing resources to meet user application demands.
