AWS IoT Greengrass makes it possible for customers to build IoT devices and application logic. Specifically, AWS IoT Greengrass provides cloud-based management of application logic that runs on devices. Locally deployed Lambda functions and connectors are triggered by local events, messages from the cloud, or other sources.

In AWS IoT Greengrass, devices securely communicate on a local network and exchange messages with each other without having to connect to the cloud. AWS IoT Greengrass provides a local pub/sub message manager that can intelligently buffer messages if connectivity is lost so that inbound and outbound messages to the cloud are preserved.
