OpenTofu for Cloud Infrastructure: A Step-by-Step Guide to Infrastructure as Code with AWS, Modules, State, CI/CD, Security, and Terraform Migration
Cloud infrastructure can feel intimidating when every tutorial assumes you already know the tools. This book starts with the basics and guides you through each step.
OpenTofu for Cloud Infrastructure is a practical, beginner-friendly guide to Infrastructure as Code (IaC) on AWS. You'll learn how to describe cloud resources with HCL, review changes before deployment, and build reliable infrastructure through hands-on exercises. No previous OpenTofu experience is required; basic command-line and cloud familiarity will help.
With clear explanations, manageable examples, and exercises you can repeat, you'll turn unfamiliar commands into useful skills. Mistakes are part of learning: the book shows you how to inspect errors, troubleshoot problems, verify results, and build confidence with each working deployment.
