DB Instances are simple to create, using either the AWS Management Console, Amazon RDS APIs, or Command Line Tools. To launch a DB Instance using the AWS Management Console, click "RDS," then the "Launch DB Instance" button on the "Instances" tab. From there, you can specify the parameters for your DB instance including DB engine and version, license model, instance type, storage type and amount, and master user credentials.
You also have the ability to change your DB Instance’s backup retention policy, preferred backup window, and scheduled maintenance window. Alternatively, you can create your DB Instance using the CreateDBInstance API or rds-create-db-instance command.
