Azure IoT Edge supports both Linux and Windows so you can code to the platform of your choice. It supports Java, .NET Core 2.0, Node.js, C, and Python so your developers can code in a language they already know and use existing business logic.
What is IoT edge runtime?
The IoT Edge runtime runs on each IoT Edge device and manages the modules deployed to each device.
How does Azure IoT Edge work?
Azure IoT Edge moves cloud analytics and custom business logic to devices so that your organization can focus on business insights instead of data management. Scale out your IoT solution by packaging your business logic into standard containers, then you can deploy those containers to any of your devices and monitor it all from the cloud.

What is sdkversion in IoT?
Some operations in IoT Hub resource logs return an sdkVersion property in their properties object. For these operations, when a device or backend app is using one of the Azure IoT SDKs, this property contains information about the SDK being used, the SDK version, and the platform on which the SDK is running. The following example shows the sdkVersion property emitted for a deviceConnect operation when using the Node.js device SDK: "azure-iot-device/1.17.1 (node v10.16.0; Windows_NT 10.0.18363; x64)". Here's an example of the value emitted for the .NET (C#) SDK: ".NET/1.21.2 (.NET Framework 4.8.4200.0; Microsoft Windows 10.0.17763 WindowsProduct:0x00000004; X86)".
What is event grid?
With Event Grid, you can subscribe to the IoT Hub DeviceConnected and DeviceDisconnected events to trigger alerts and monitor device connection state. Event Grid provides much lower event latency than Azure Monitor, and you can monitor on a per-device basis, rather than for the total number of connected devices. These factors make Event Grid the preferred method for monitoring connections for critical devices and infrastructure. We highly recommend using Event Grid to monitor device connections in production environments.
