This Terraform configuration creates:
- Amazon AWS VPC
- Internet Gateway
- Subnets in all configured availability zones and routing tables linking them to the Internet Gateway
Additionally, if variable private_subnets is set to true, it will create:
- NAT with Elastic IP address in each availability zone
- Private subnet in each availability zone with routing tables linking them to the NAT
This configuration uses my own module from Terraform Module Registry.
There are no other dependencies apart from Terraform.
