-- 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.
--
-- When you make a request, you will get a 200 OK success response
-- immediately. However, it might take some time for the gateway to be
-- ready. You should call DescribeGatewayInformation and check the status
-- before making any additional API calls. For more information, see
-- ActivateGateway.
--
-- To specify which gateway to start, use the Amazon Resource Name (ARN) of
-- the gateway in your request.
