The Amazon Relational Database Service (RDS) may be accessed from the Amazon RDS tab of the AWS Console.
The Amazon Relational Database Service (RDS) provides SQL services within the AWS infrastructure using MySQL as the database engine. The RDS provides access to the full featured database engine provided by MySQL and allows full access to the database.
RDS features automatic backups, that can be retained for up to eight days. In the event that a more permanent backup is required, a snapshot can be taken of an RDS instance and stored in S3 indefinitely.
RDS uses two technologies to create an available and redundant architecture. Redundancy is provided by the Multi-AZ Deployments option when creating an RDS instance. When this option is checked, two copies are created of your RDS instance, one in your selected availability zone, and one in an alternative availability zone. The second instance is not visible or available.
