AWS has introduced a feature called Reporting for Required Tags within its Tag Policies framework, aimed at ensuring that deployments using CloudFormation, Terraform, and Pulumi comply with specific tagging requirements. This feature helps organizations maintain consistent tagging across their AWS resources, which is essential for governance, compliance, and effective resource management. Users can define mandatory tags—like “Environment,” “Owner,” and “Application”—for their infrastructure-as-code (IaC) deployments. To implement this, users must first define their tag policies and then enable validation in their chosen IaC tool. For instance, in CloudFormation, you can activate the AWS::TagPolicies::TaggingComplianceValidator Hook. Terraform requires adding validation logic in the plan, while Pulumi users can activate a pre-built policy pack. Once set up, all relevant deployments in the specified AWS account will be automatically checked against these policies, ensuring that resources are tagged correctly. The Reporting for Required Tags feature is accessible through the AWS Management Console, AWS Command Line Interface, and AWS SDK. It's available in AWS Regions where Tag Policies are supported. For those looking to implement this feature, AWS provides detailed user guides for CloudFormation and Terraform, alongside a blog post for Pulumi. This level of automation saves time and reduces the risk of non-compliance in tagging, which can lead to operational inefficiencies and increased costs.
