IaC
A methodology that manages and provisions computing infrastructure using machine-readable definition files, enabling automation, consistency, and version control.
Infrastructure as Code (IaC) is a practice that uses code and configuration files to define, provision, and manage IT infrastructure. By treating infrastructure as software, IaC enables automation, repeatability, and version control, reducing manual intervention and configuration drift.
IaC tools—such as Terraform, AWS CloudFormation, and Ansible—allow organizations to deploy infrastructure rapidly, enforce best practices, and maintain consistent environments across development, testing, and production. IaC supports DevOps workflows, continuous delivery, and cloud-native operations.
Adopting IaC enhances agility, lowers operational risk, and empowers teams to innovate quickly by making infrastructure changes traceable and reversible.
