What is Azure IoT Edge for Linux on Windows

Applies to: IoT Edge 1.4

Azure IoT Edge for Linux on Windows (EFLOW) allows you to run containerized Linux workloads alongside Windows applications in Windows deployments. Businesses that rely on Windows to power their edge devices and solutions can now take advantage of the cloud-native analytics solutions being built in Linux.

Azure IoT Edge for Linux on Windows works by running a Linux virtual machine on a Windows device. The Linux virtual machine comes pre-installed with the Azure IoT Edge runtime. Any Azure IoT Edge modules deployed to the device run inside the virtual machine. Meanwhile, Windows applications running on the Windows host device can communicate with the modules running in the Linux virtual machine.

Components

Azure IoT Edge for Linux on Windows uses the following components to enable Linux and Windows workloads to run alongside each other and communicate seamlessly:

• A Linux virtual machine running Azure IoT Edge: A Linux virtual machine, based on Azure's first party CBL-Mariner operating system, is built with the Azure IoT Edge runtime and validated as a tier 1 supported environment for Azure IoT Edge workloads.

• Microsoft Update: Integration with Microsoft Update keeps the Windows runtime components, the CBL-Mariner Linux VM, and Azure IoT Edge up to date. For more information about IoT Edge for Linux on Windows updates, see Update IoT Edge for Linux on Windows.

Bi-directional communication between Windows process and the Linux virtual machine means that Windows processes can provide user interfaces or hardware proxies for workloads run in the Linux containers.
