Amazon Relational Database Service (Amazon RDS) is a web service that that allows you to quickly create a relational database instance in the cloud. Amazon RDS manages the database instance on your behalf by performing backups, handling failover, and maintaining the database software.

For read-heavy applications, you can launch Read Replicas which are RDS instances that serve as copies of the source master database for handling read-requests. You can attach up to five (5) Read Replicas to a source DB instance.

The Instances page lists the existing RDS Instances in the selected AWS region. Clicking on an existing RDS Instance displays the details for that instance.


  • Name - unique name/identifier for the RDS instance.
  • Engine - The version of the MySQL or Oracle engine of the RDS Instance.
  • RDS Subnet Group - The group of RDS Subnets for the VPC.
  • Availability Zone - The availability zone into which the RDS Instance will be created and launched.
  • Multi-AZ - Indicates that the RDS Instance will be used in a multiple availability zone configuration.
  • Instance class - If you selected a different instance type, the existing instance will be terminated and new RDS instance will be launched.
  • Storage - storage size in GBs for the instance that will be allocated for storing data.
  • Source instance - If the instance is a Read Replica, it will list the name of the source DB instance.
  • Status - The status of the RDS Instance (creating, modifying, available, rebooting, deleting). An RDS Instance will only be accessible when its status is 'available'.
