How do I build my first AWS VPC with Terraform?

Use `main.tf` with VPC, subnets (public/private), IGW, NAT, route tables. `terraform apply` in 25 mins—destroy after.

What is a VPC in AWS and why use it?

Isolated virtual network (CIDR/subrets). Protects EC2/DBs from internet; essential for secure apps.

Does Terraform save money on AWS VPC setup?

Yes—$0.05 tests, auto-destroy NAT ($32/mo trap). Variables prevent waste. And that's your launchpad. Code it. Own the cloud.
