The IoT protocol MQTT has existed since 1998, but its popularity has blossomed since open source implementations of both clients and servers became widely available. Two of the most popular implementations have homes in the Eclipse Foundation: the Paho clients and Mosquitto server.
Jakarta EE is the new name for the evolution of JavaEE within the Eclipse Foundation. Many people think of Java EE as a heavyweight Enterprise solution for big scale. In this talk I would like to dispel this myth demonstrating how light-weight JavaEE based microservices can run on small platforms and integrate with IOT technologies like Eclipse Mosquito for messaging. In this code driven talk you will learn how to use the JavaEE JCA specification to create a connector to MQTT and to drive event driven microservices running on JavaEE on Raspberry PIs.
The Internet of Things (IoT) revolves around the development, mass-production and deployment of wireless embedded sensor devices. A plethora of prototyping platforms for exploring and developing those sensor nodes exists. However many of those toolkits do not scale beyond prototyping or offer an inferior development experience compared to other domains, e.g. mobile-apps or the web. To overcome the rigidity of the conventional embedded IoT device development process, we are building Mita: a new programming language designed for the embedded IoT.
Eclipse Cyclone DDS is an implementation of the Data Distribution Service (DDS), a standard for interoperable, secure, and efficient data sharing, used at the foundation of some of the most challenging Consumer and Industrial IoT applications, such as Smart Cities, Autonomous Vehicles, Smart Grids, Smart Farming, Home Automation and Connected Medical Devices.
The continuous evolution of the automotive domain raises challenges towards autonomous driving and additionally necessitates the utilization of cloud and IoT technologies in order to cope with advanced customer services. Open source projects potentially transcend the capabilities of proprietary and commercial products due to the transparent use of a dense and intertwined set of methodologies, protocols, tools, and connectivity approaches. The newly established Eclipse Kuksa project is part of the Eclipse IoT working group and aims at establishing an open connected vehicle ecosystem.
The democratisation of connectity and computational capabilities are making it possible for virtually anything to be connected and thus to share data as well as take decentralised decisions. Several of these new devices gaining connectivity are powered by small micro-controllers, connected through LoWPAN or LPWAN and in most of the cases battery-powered. As a consequence of the expanded connectivity, the scale of systems is growing, as it is the level of asymettry.
Now that there’s consensus that DATA is the currency of IoT, a “Data-River” is required that assures robust, timely and secure end-to-end delivery and availability of that data i.e. from highly-embedded devices in the OT-domain via microservices that create information from that ‘raw data’ (by combining, normalizing, transforming, filtering and which run either at the edge or in a cloud) up to end-users that exploit the value from that information (e.g. by increasing efficiency, applying preventive maintenance etc).
Device connectivity is one of the most common issues IoT developers need to solve. Having an open source solution based on the standardized protocols that solves recurring connectivity problems is a very useful tool to have.
Meet Eclipse Hono, a cloud-based IoT connectivity platform which provides remote interfaces for device connectivity and mechanisms for uniform interaction with devices regardless of the communication protocol.
