AirFrance-KLM transformed its automation platform using Terraform, Vault, and Ansible to enhance security, compliance, and efficiency. The shift from compliance-by-construction to compliance-by-guardrails streamlined their processes, reducing provisioning time and errors while maintaining governance.

AWS now allows you to validate and enforce required tags in CloudFormation, Terraform, and Pulumi using Tag Policies. By defining mandatory tags like "Environment," "Owner," and "Application," you can ensure consistent tagging across your infrastructure-as-code projects. This feature helps maintain compliance and governance for your AWS resources.

Implementing guardrails in cloud infrastructure is essential to prevent security vulnerabilities, unexpected costs, and compliance issues. The article explains how Open Policy Agent (OPA) can be integrated with Terraform to enforce policies as code, ensuring consistent governance and security for cloud resources. It provides practical policy examples and steps for integrating OPA into Terraform workflows.
