> Infrastructure as Code (IaC) manages servers, networks and cloud resources through version-controlled configuration files instead of manual setup. It makes environments reproducible, reviewable and easy to rebuild.

Tools like Terraform define infrastructure declaratively, so an environment can be recreated identically and changes are auditable. IaC eliminates configuration drift and is essential for reliable, scalable cloud operations.
