Lambda Layer Version
AWS Lambda Layer Version represents an immutable, version-numbered snapshot of a Lambda layer—an archive of shared code, libraries, custom runtimes or other assets that can be attached to multiple Lambda functions. Each time you publish a layer you create a new layer version, referenced in the form arn:aws:lambda:<region>:<account-id>:layer:<layer-name>:<version-number>. Using layers helps decouple shared dependencies from individual function packages, streamline updates and encourage code reuse across your serverless estate.
