You can now add tags to your AWS Lambda functions. Using tags, you can now add metadata to each of your functions. Each tag consists of a key and value. You can use these tags to allocate costs from your AWS bill to individual functions. There is no additional charge for tagging your Lambda functions.
Previously, you needed to build custom solutions or use log analysis in order to organize, filter, or allocate your costs by function. Now, you can easily organize your functions into groups and filter them by tag using the Lambda API and Lambda console.
