We are excited to announce that AWS CloudFormation now supports tags for Amazon RDS and Amazon S3 resources. AWS CloudFormation makes it easy for you to provision and configure a set of related resources. Tagged resources allow you to view your AWS usage based on your business dimensions (such as cost centers, application names, or owners). With cost allocation reports, you can also track your AWS costs by tag.
CloudFormation automatically adds preset tags to your EC2, S3, and RDS resources. These preset tags contain the stack name and ID. Additionally, you can specify your custom tags at the stack level and have them propagate to all resources. Alternatively, you can specify tags for specific resources in your template, allowing you fine-grained control over what resources get tagged.
