-- 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.
