Eclipse Kura™ is an extensible open source IoT Edge Framework based on Java/OSGi. Kura offers API access to the hardware interfaces of IoT Gateways (serial ports, GPS, watchdog, GPIOs, I2C, etc.). It features ready-to-use field protocols (including Modbus, OPC-UA, S7), an application container, and a web-based visual data flow programming to acquire data from the field, process it at the edge, and publish it to leading IoT Cloud Platforms through MQTT connectivity. The emergence of an Internet of Thing (IoT) service gateway model running modern software stacks, operating on the edge of an IoT deployment as an aggregator and controller, has opened up the possibility of enabling enterprise-level technologies to IoT gateways. Advanced software frameworks, which abstract and isolate the developer from the complexity of the hardware and the networking sub-systems, re-define the development and re-usability of integrated hardware and software solutions.
