AWS Lambda now supports tagging Event Source Mappings (ESM) and Code Signing Config (CSC) resources. Tags are simple key-value pairs that customers can assign to AWS resources to easily organize, search, identify resources, and control access.
Previously, customer tagging was limited to Lambda Function resources. With today’s launch, customers can now use tag-based controls to manage access to ESM or CSC resources used with their Lambda functions. Customers can manage tags for ESM and CSC resources using the AWS CLI, AWS SDKs, AWS CDKs, AWS SAM, AWS CloudFormation or AWS Management Console.
Lambda support for tagging ESM and CSC resources is available at no additional cost in all AWS Regions where AWS Lambda is available, except the AWS GovCloud (US) Regions and the China Regions.
To learn more, visit the Lambda documentation page on how to use tags on ESM and CSC.
