Terraform Learning Path

This repository contains my learning journey and hands-on practice while completing a comprehensive Terraform Learning Path focused on Infrastructure as Code (IaC). All the content here is based on structured lessons and practical exercises from a Terraform course, organized to reflect a progressive understanding from fundamentals to more advanced concepts.

The goal of this repository is to serve as a reference, practice ground, and knowledge base for Terraform concepts, syntax, and best practices.

• Incremental examples following Terraform best practices
• Clear separation of concepts (providers, variables, functions, modules, etc.)
• Practical infrastructure definitions written in HCL
• Reusable and maintainable Terraform configurations
• Learning-oriented structure aligned with a real-world Terraform workflow
