This module provides the essential foundation for understanding and working with Infrastructure as Code (IaC) using Terraform. Before you can secure infrastructure, you must understand how it is defined and deployed. You will learn the core principles of the shift-left paradigm for cloud environments, the structure of HashiCorp Configuration Language (HCL), and how Terraform interacts with cloud providers. We will cover the lifecycle of resources, the critical concept of state management, and how to parameterize configurations using variables and outputs. The module culminates in a hands-on guided lab where you will write, validate, and apply your first Terraform configuration to provision a secure cloud resource.
