Infrastructure as Code Fundamentals
Why infrastructure as code matters, declarative thinking, Terraform and OpenTofu basics, state, modules and CI pipelines.
Infrastructure as code (IaC) describes networks, servers, storage and permissions in files you can review, version and reuse. This course explains why teams adopt IaC, how declarative tools differ from scripts, how to write and apply a basic Terraform or OpenTofu configuration, how state is managed, and how modules and CI pipelines make changes safer.
What you'll learn
- Why IaC reduces risk and speeds up change
- Declarative and imperative approaches, and why the difference matters
- Writing, planning and applying a Terraform or OpenTofu configuration
- How state works and how to store it safely
- Using modules and running IaC through a CI pipeline
