AWS::EC2::NatGateway AvailabilityZoneAddress

For regional NAT gateways only: The configuration specifying which Elastic IP address (EIP) to use for handling outbound NAT traffic from a specific Availability Zone.

A regional NAT gateway is a single NAT Gateway that works across multiple availability zones (AZs) in your VPC, providing redundancy, scalability and availability across all the AZs in a Region.

For more information, see Regional NAT gateways for automatic multi-AZ expansion in the Amazon VPC User Guide.
