What is Infrastructure as Code (IaC) and how does it improve cloud operations?

• A. Using code to provision infrastructure; enables versioning, repeatability, automation, quick recovery, reduced human error.
• B. A type of proprietary management console
• C. A manual process for hardware provisioning
• D. A security policy framework

Answer: (D)

Infrastructure as Code means describing the desired state of cloud resources in machine-readable code that can be stored, versioned, and applied automatically. By treating infrastructure like software, you can provision, configure, and manage resources through automated processes rather than manual steps. This brings version control and change tracking, so you can review and test changes, roll them back if needed, and reproduce environments consistently across development, staging, and production.

This approach also enables repeatable deployments, reduces human error from manual setup, accelerates provisioning and recovery, and fits naturally into automated deployment pipelines. The choice that describes using code to provision infrastructure and highlights benefits like versioning, repeatability, automation, quick recovery, and reduced human error best captures what IaC is and why it improves cloud operations. The other options describe a management console, a manual provisioning process, or a security policy framework, none of which describe IaC.
