Eclipse Kura™, an extensible open-source IoT Edge Framework, is based on Java/OSGi. Kura provides API access to IoT Gateways' hardware interfaces (serial ports and GPS, watchdog, I2C, GPIOs, I2Cs, etc.). It includes ready-to-use field protocols, including Modbus, OPCUA, S7, and an application container. A web-based visual flow programming allows you to acquire data from the field and process it at the edge. Then, it publishes it to the leading IoT Cloud Platforms via MQTT connectivity. Modern software stacks are running on an Internet of Thing (IoT), service gateway model. It acts as an aggregator/controller at the edge of an IoT deployment. This opens up the possibility of enabling enterprise level technologies to IoT gateways. Advanced software frameworks are able to isolate the developer from the complexity and sub-systems of the networking and allow for the development and reuse of integrated hardware and software solutions.
