AWS OpsWorks Stacks now supports custom tagging for AWS resources, improving the ability to organize your resources and report on AWS cost allocation. Previously, you had to manually add and maintain custom tags on all OpsWorks managed resources. Now you can leverage OpsWorks for tag management. After you apply tags to a stack or layer, OpsWorks propagates the tags down to Amazon EC2, Elastic Load Balancing, Amazon RDS, and Amazon Elastic Block Store resources. This makes it easy to break down costs on an environment, application, or software component level. You can apply tags through the OpsWorks console, the CLI, SDK, or API.
