-- Creates a transit gateway.
--
-- You can use a transit gateway to interconnect your virtual private
-- clouds (VPC) and on-premises networks. After the transit gateway enters
-- the @available@ state, you can attach your VPCs and VPN connections to
-- the transit gateway.
--
-- To attach your VPCs, use CreateTransitGatewayVpcAttachment.
--
-- To attach a VPN connection, use CreateCustomerGateway to create a
-- customer gateway and specify the ID of the customer gateway and the ID
-- of the transit gateway in a call to CreateVpnConnection.
--
-- When you create a transit gateway, we create a default transit gateway
-- route table and use it as the default association route table and the
-- default propagation route table. You can use
-- CreateTransitGatewayRouteTable to create additional transit gateway
-- route tables. If you disable automatic route propagation, we do not
-- create a default transit gateway route table. You can use
-- EnableTransitGatewayRouteTablePropagation to propagate routes from a
-- resource attachment to a transit gateway route table. If you disable
-- automatic associations, you can use AssociateTransitGatewayRouteTable to
-- associate a resource attachment with a transit gateway route table.
