Description: >
    This template deploys a VPC, with a pair of public and private subnets spread
    across two Availabilty Zones. It deploys an Internet Gateway, with a default
    route on the public subnets. It deploys a pair of NAT Gateways (one in each AZ),
    and default routes for them in the private subnets.
