Comparison between Eclipse Kura and EdgeXFoundry

IoT edge gateways devices need a software ecosystem which complements features offered by state-of-the-art IoT Platforms. By nature, problems solved by Internet of Thing is huge and therefore building a software system which caters to all types of requirements is a tough nut to crack.

The goal of IoT Edge Middlewares is to support variety of use cases that may be required to support plethora of industries.

IoT Edge gateways are an aggregation point of group of sensors and actuators. In a typical IoT setup, an Edge Gateway senses data from sensor nodes and exposes them to IoT platform.

In order to provide a general purpose environment which is applicable to a large number of use cases, Edge Gateways need a general purpose middleware which facilitates communication between sensors and gateways and to cloud. Following are some of the most popular stacks for IoT Edge Gateways

  1. Eclipse Kura
  2. EdgeXFoundry

Github Repo.KuraEdgeX Go
OS SupportUbuntu Core,Raspbian, Linux (Ubuntu/Ubuntu Core, Yocto-based linux distribution), Windows.Ubuntu Core,Raspbian, Linux (Ubuntu/Ubuntu Core, Yocto-based linux distribution), Windows.
Application RuntimeJava Virtual Machine (JVM)Does not require any specific runtime. One of the key tenets of EdgeXFoundry is to be platform independent and hence it allows microservices written in Java, Javascript, Python, Go, C/C++ to work together through common APIs.
Web based Administration Console allows user to do network, sensor related configurations.EdgeX GUI is a work in progress. Checkout this Github repository.
Database support for local persistenceSupports H2, the Java SQL database for storing telemetry as well as configurations locally in IoT Gateway.Supports MongoDB and Redis at the persistence layer.
IoT Cloud Platforms support Eurotech Everyware Cloud™ platform
Amazon AWS IoT™ platform
Azure IoT Hub™ platform
Eclipse Kapua™ platform
Eclipse Hono™ platform
Supports integration with Google IoT Core out of the box.
User can write their own “Export Service” to integrate with other cloud platforms.
