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'.
