Quick Reference: Key Concepts and Terminology

  • Azure IoT Edge is made up of three components:
    • IoT Edge Runtime - Runs on each IoT Edge device and manages the modules deployed to each device.
      System Modules
      • IoT Edge security daemon - Starts each time an IoT Edge device boots and bootstraps the device by starting the IoT Edge agent.
      • IoT Edge agent - Manages deployment and monitoring of modules on the IoT Edge device, including the IoT Edge hub.
      • IoT Edge hub - Handles communications between modules on the IoT Edge device, and between the device and IoT Hub
    • IoT Edge Modules - Containers that run Azure services, third-party services, or your own code. Modules are deployed to IoT Edge devices and execute locally on those devices.
      • Module image - A package containing the software that defines a module.
      • Module instance - The specific unit of computation running the module image on an IoT Edge device. The module instance is started by the IoT Edge runtime.
      • Module identity - A piece of information (including security credentials) stored in IoT Hub, that is associated to each module instance.
      • Module twin - A JSON document stored in IoT Hub, that contains state information for a module instance, including metadata, configurations, and conditions.
      • SDKs to develop custom modules in multiple languages (C#, C, Python, Java, Node.JS)
    • Cloud-based Interface - Enables you to remotely monitor and manage IoT Edge devices.
  • Module Twin Properties of Edge Runtime Modules:
    • Desired and Reported properties
    • EdgeAgent properties
    • EdgeHub properties
