Abstract

AWS Greengrass Nucleus is an open-source Internet of Things (IoT) project. The Greengrass nucleus component provides functionality for device side orchestration of deployments and lifecycle management for execution of Greengrass components and applications. This includes features such as starting, stopping, and monitoring execution of components and apps, interprocess communication server for communication between components, component installation and configuration management. It is built using Java, AWS. The complete source code is publicly available on GitHub under the Apache License 2.0, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.

1. Introduction

The Greengrass nucleus component provides functionality for device side orchestration of deployments and lifecycle management for execution of Greengrass components and applications. This includes features such as starting, stopping, and monitoring execution of components and apps, interprocess communication server for communication between components, component installation and configuration management.

2. Objective

The Greengrass nucleus component provides functionality for device side orchestration of deployments and lifecycle management for execution of Greengrass components and applications. This includes features such as starting, stopping, and monitoring execution of components and apps, interprocess communication server for communication between components, component installation and configuration management.

This project demonstrates how Java, AWS can be applied to a real-world Internet of Things (IoT) problem.
