-- | This operation starts a gateway that you previously shut down (see 'ShutdownGateway'). After the gateway starts, you can then make other API calls, your
-- applications can read from or write to the gateway's storage volumes and you
-- will be able to take snapshot backups.
--
-- To specify which gateway to start, use the Amazon Resource Name (ARN) of the
-- gateway in your request.
