What is Amazon RDS ?
Amazon Relational Database Service (RDS) makes it easy to set up, operate, and scale a database in the cloud. It provides cost-efficient and resizable capacity while automating time-consuming administration tasks such as hardware provisioning, setup, patching, and backups. It frees you to focus on your applications. Amazon RDS is available on several database instance types - optimized for memory, performance or I/O - and provides you with six familiar database engines to choose from.
