* It provides **cost-efficient, resizable capacity for an industry-standard relational database** and **manages common database administration tasks**.<br>
* When you buy a server, you **get CPU, memory, storage, and IOPS, all bundled together**.<br>
* RDS **manages backups, software patching, automatic failure detection, and recovery**.<br>
