Infrastructure as Code (IaC)

Infrastructure as Code (IaC) means defining servers, networks, IAM, and managed services in version-controlled files instead of clicking consoles—so environments are reproducible, reviewable, and automated. Tools like Terraform and Pulumi apply declarative or programmatic specs to AWS, GCP, Azure, and Kubernetes. Good IaC pairs with CI pipelines and policy checks so drift is visible, not silent.
