AWS network in code: one command takes an empty AWS account to a running web server.
Terraform builds a custom VPC, public subnet, internet gateway, route tables, security groups, an EC2 instance and an Elastic IP. Ansible then installs Docker and deploys NGINX, and a validation step checks SSH, Docker and the live web page.
Why it matters for a small business: the whole setup is repeatable, reviewable and easy to tear down, so nothing is clicked together by hand and forgotten. Code: github.com/nujabesploo/aws-terraform-ansible-platform
