Build IoT solutions for the enterprise using open-source building blocks from the Eclipse IoT Working Group at the Eclipse Foundation. This book introduces you to key protocols and their implementations, such as CoAP (Eclipse Californium), DDS (Eclipse Cyclone DDS), LwM2M (Eclipse Leshan), and MQTT (Eclipse Paho, Eclipse Mosquitto, and Eclipse Amlen). You will learn about Edge Computing platforms (Eclipse ioFog, Eclipse Kanto), IoT gateways (Eclipse Kura, Eclipse Kapua), and next-generation edge native protocols (Eclipse zenoh).The book also covers production-ready platforms for digital twins (Eclipse Ditto), energy management (Eclipse VOLTTRON), contactless payments (Eclipse Keyple), and much more.Although the book discusses hardware matters, its focus is on software and relevant open standards. The book helps you understand the pros and cons of the technologies available from Eclipse IoT and how they have been used in actual deployments. The examples provided cover a variety of use cases, such as industrial automation, smart agriculture, digital buildings, robotics, and others.The book's contents follow a reference architecture encompassing constrained devices (things), edge devices (gateways, servers), and IoT Cloud platforms. For each of those three pillars, you will learn about relevant open-source components. Usage of code libraries and frameworks is explained through code samples. You will also learn how to deploy and configure platform-type components and how to leverage them. Special attention will be paid to security and edge computing throughout the book. What You Will LearnDescribe in your own words the main software components required in an IoT architectureSelect the appropriate IoT protocols, components, frameworks, and platforms for a specific projectEvaluate the connectivity options at your disposal and select the most appropriate onesExplain the value of business models focused on open-source components and deploy such models in your organizationDetermine if edge computing is relevant to a project and deploy the relevant components on an edge computing platformBuild Enterprise IoT solutions leveraging an array of open-source components and platforms using popular languages such as C, Java, and RustWho This Book Is ForDevelopers new to enterprise IoT who want to learn about fundamental technologies for that market segment and seek an introduction to relevant, open-source building blocks; experienced IoT developers who seek alternatives to the proprietary platforms they are currently using; software architects designing IoT solutions who want to understand open-source technology options
