# Greengrass Function Definition

Greengrass Function Definition in AWS represents a collection of Lambda functions that can be deployed and run on Greengrass core devices. It defines the configuration and metadata for these functions, including versioning and deployment details, enabling edge devices to execute code locally while still integrating with AWS cloud services.
