            With Amazon EC2 Reserved Instances, you purchase the right
            to launch Amazon EC2 instances for a period of time (without
            getting insufficient capacity errors) and pay a lower usage rate for
            the actual time used.
            
            For more information about Reserved Instances, go to the Amazon
            Elastic Compute Cloud Developer Guide.
