  Creates a NAT gateway in the specified public subnet. This action creates a network interface in the specified
  subnet with a private IP address from the IP address range of the subnet. Internet-bound traffic from a private
  subnet can be routed to the NAT gateway, therefore enabling instances in the private subnet to connect to the
  internet. For more information, see <a
