Infrastructure as Code Review

Infrastructure as Code (IaC) Review is a systematic process for evaluating and validating infrastructure code (e.g., Terraform, CloudFormation, Ansible scripts) to ensure it meets quality, security, compliance, and operational standards. It involves analyzing code for best practices, potential vulnerabilities, cost optimization, and adherence to organizational policies, often using automated tools and manual inspections. This practice helps prevent misconfigurations, reduce deployment risks, and maintain consistent, reliable infrastructure deployments.

Also known as: IaC Review, Infrastructure Code Review, Terraform Review, Cloud Infrastructure Review, Infra Code Audit

Why learn Infrastructure as Code Review?

Developers should learn and use IaC Review to catch errors early in the development lifecycle, such as security flaws or inefficient resource usage, which can lead to costly outages or breaches in production. It is critical in DevOps and cloud-native environments where infrastructure changes are frequent, ensuring compliance with regulations (e.g., GDPR, HIPAA) and enabling scalable, repeatable deployments. Use cases include code reviews in CI/CD pipelines, pre-deployment checks for cloud resources, and auditing infrastructure for governance in teams using tools like Terraform or AWS CloudFormation.
