Amazon Relational Database Service (Amazon RDS) is a web service that makes it easier to set up, operate, and scale a relational database in the cloud. AWS RDS takes over many of the difficult or tedious management tasks of a relational database. When you use Amazon RDS, you can choose to use on-demand DB instances or reserved DB instances.
Relational Database Types
What AWS does with RDS?
A DB instance can contain multiple user-created databases, and you can access it by using the same tools and applications that you use with a stand-alone database instance. You can create and modify a DB instance by using the AWS Command Line Interface, the Amazon RDS API, or the AWS Management Console.
You can select the DB instance that best meets your needs. If your needs change over time, you can change DB instances. DB instance storage comes in three types: Magnetic, General Purpose (SSD), and Provisioned IOPS (PIOPS). They differ in performance characteristics and price, allowing you to tailor your storage performance and cost to the needs of your database.
A security group controls access to a DB instance. It does so by allowing access to IP address ranges or Amazon EC2 instances that you specify.
There are several ways that you can track the performance and health of a DB instance. You can use the free Amazon CloudWatch service to monitor the performance and health of a DB instance; performance charts are shown in the Amazon RDS console. You can subscribe to Amazon RDS events to be notified when changes occur with a DB instance, DB Snapshot, DB parameter group, or DB security group.
