Endorsed Linux distributions on Azure
Applies to: ✔️ Linux VMs ✔️ Flexible scale sets ✔️ Uniform scale sets
Partners provide Linux images in Azure Marketplace. For distributions that are not available from the Marketplace, you can always bring your own Linux by following the guidelines at Create and upload a virtual hard disk that contains the Linux operating system.
For more information, see Support for Linux images in Microsoft Azure.
The Linux Integration Services (LIS) drivers for Hyper-V and Azure are kernel modules that Microsoft contributes directly to the upstream Linux kernel. Some LIS drivers are built into the distribution's kernel by default. Older distributions that are based on Red Hat Enterprise (RHEL)/CentOS are available as a separate download at Linux Integration Services Version 4.2 for Hyper-V and Azure. For more information, see Linux kernel requirements.
The Azure Linux Agent is already pre-installed on Azure Marketplace images and is typically available from the distribution's package repository. Source code can be found on GitHub.
credativ is an independent consulting and services company that specializes in the development and implementation of professional solutions by using free software. As leading open-source specialists, credativ has international recognition with many IT departments that use their support. In conjunction with Microsoft, credativ is preparing Debian images.

Image update cadence
Azure requires that the publishers of the endorsed Linux distributions regularly update their images in Azure Marketplace with the latest patches and security fixes, at a quarterly or faster cadence. Updated images in the Marketplace are available automatically to customers as new versions of an image SKU. More information about how to find Linux images: Find Linux VM images in Azure Marketplace.
Azure works closely with various endorsed Linux distributions to optimize the images that they published to Azure Marketplace. One aspect of this collaboration is the development of "tuned" Linux kernels that are optimized for the Azure platform and delivered as fully supported components of the Linux distribution. The Azure-Tuned kernels incorporate new features and performance improvements, and at a faster (typically quarterly) cadence compared to the default or generic kernels that are available from the distribution.
In most cases, you will find these kernels pre-installed on the default images in Azure Marketplace so customers will immediately get the benefit of these optimized kernels. More information about these Azure-Tuned kernels can be found in the following links:
