# Greengrass Device Definition

Greengrass Device Definition in AWS represents a group of devices, such as IoT things, that can interact with an AWS Greengrass group. It defines the set of devices that can communicate securely with the Greengrass core, enabling local messaging, data processing, and integration with cloud services. This resource helps manage and organize devices for edge computing scenarios.
