INTRODUCTION Welcome to Day 3 of my 30-Day Terraform Challenge! In the "ancient" days of software, deploying a server was a manual, fragile process involving physical hardware and manual commands Today, we use Infrastructure as Code (IaC) to automate this entire process using a simple, declarative language if you are just starting out, this guide walks you through the exact steps I took to launch my first virtual server on AWS.
