Nowadays I am working about CloudFormation in AWS. It’s a really time consumer IAC tool. Maybe the reason that I blame it like that is that I am newbie about AWS. But honestly I tried Terraform and I feel better while using it.

Requirements for creating NATGateway
- Creating EIP
- Associating it with NATGateway
