What is IaC?

Infrastructure as Code (IaC) is the practice of defining and managing infrastructure—such as networks, virtual machines, load balancers, and storage—through code instead of manual configuration. These machine-readable definition files are typically written in declarative or imperative languages, allowing infrastructure to be version-controlled, peer-reviewed, and automated just like application code. IaC improves consistency, reduces human error, accelerates provisioning, and enables scalable, repeatable deployments across development, staging, and production environments.
