Description: >

    This template:
      deploys a VPC to paired public and private subnets (for four total) across two Availabilty Zones
        Public side deployment contains:
          Single Internet Gateway with a default route
          Pair of NAT Gateways located one in each availability zone

        Private:
          Default routes to the NAT Gateways
          Highly available ECS cluster using an AutoScaling Group for deploy
          ECS hosts distributed across multiple Availability Zones (hosts for the containers)

          Application: it deploys a pair of example ECS services from containers published in Amazon EC2 Container Registry (Amazon ECR).
