This Terraform code will deploy one of two typical AWS VPC configurations.
In both cases, the following items will be deployed :
- An AWS VPC
- Public subnets with an associated Internet Gateway (IGW) in the specified number of availability zones.
- Two Private subnets in the specified number of availability zones.
If the variable createNATGateways is set to true, the following will also be created:
- A NAT Gateway in each public subnet
- Routing to allow items in the private subnet to access the Internet via the appropriate NAT Gateway.
