# Greengrass Resource Definition

Greengrass Resource Definition in AWS represents a collection of local resources, such as devices, volumes, or machine learning models, that can be made accessible to AWS Greengrass groups. It allows you to define and manage how these resources are exposed to and used by Greengrass Lambda functions running on edge devices.
