-- Launches the specified Scheduled Instances.
--
--
-- Before you can launch a Scheduled Instance, you must purchase it and obtain an identifier using 'PurchaseScheduledInstances' .
--
-- You must launch a Scheduled Instance during its scheduled time period. You can't stop or reboot a Scheduled Instance, but you can terminate it as needed. If you terminate a Scheduled Instance before the current scheduled time period ends, you can launch it again after a few minutes. For more information, see <http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-scheduled-instances.html Scheduled Instances> in the /Amazon Elastic Compute Cloud User Guide/ .

--
-- * 'rsiLaunchSpecification' - The launch specification. You must match the instance type, Availability Zone, network, and platform of the schedule that you purchased.
