"Description" : "AWS CloudFormation Sample Template VPC_with_PublicIPs_And_DNS.template: Sample template showing how to create a multi-tier VPC with multiple subnets DNS support. The instances have automatic public IP addresses assigned. The first subnet is public and contains a NAT device for internet access from the private subnet and a bastion host to allow SSH access to the hosts in the private subnet. You will be billed for the AWS resources used if you create a stack from this template.",
