-- | This operation activates the gateway you previously deployed on your host.
-- For more information, see <http://docs.aws.amazon.com/storagegateway/latest/userguide/GettingStartedActivateGateway-common.html  Activate the AWS Storage Gateway>. In the
-- activation process, you specify information such as the region you want to
-- use for storing snapshots, the time zone for scheduled snapshots the gateway
-- snapshot schedule window, an activation key, and a name for your gateway. The
-- activation process also associates your gateway with your account; for more
-- information, see 'UpdateGatewayInformation'.
