Linux and open-source technology support in Azure

  • Article

Microsoft Azure supports the Linux operating system. All Linux distributions are welcome in Azure. To upload your Linux distribution to Azure, see the requirements. Marketplace images of the most popular Linux distributions are also available. Support for these images is available but requires a support contract. See the following Linux support for more details.

Azure Endorsed Distribution
  • SUSE on Azure
  • SUSE has three offerings in Azure:

    • Bring Your Own Subscription (BYOS)

      Customers must register with SUSE to use these images. Microsoft may provide guidance for Linux issues, but may defer customer issues to SUSE directly.

    • SUSE Images with Patching Support

      These images include updates for your VM from SUSE. Microsoft may assist with Linux issues, but these images don't include extra support from SUSE. SUSE-related inquiries may require customers to engage with SUSE directly and require an active SUSE support agreement.

    • 24x7 Support Images

      These images include updates and support from Microsoft through the web, email, chat, and telephone. SUSE supports these images daily, as defined in their support policies for public cloud images in the SUSE Public Cloud Guide. These images are considered SUSE Level 3 subscriptions. VMs that are created from these images incur per-hour support fees and Azure platform fees.

      • Conversion between PAYG offerings to BYOS can be done through Azure Hybrid Benefit. For more information, see Azure Hybrid Benefit for Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES) virtual machines.

Linux support scope

Microsoft Support provides assistance with the Azure platform or services. Microsoft also provides commercially viable support for Linux. A support plan is required to receive Microsoft Support.

  • In Azure Marketplace, Linux distributions such as Rocky, AlmaLinux, Kali, and many others are available. Microsoft assists with these distributions but may require customers to engage with vendors to allow collaboration between organization. Vendors must provide distribution-specific fixes.
  • In Azure Marketplace, you may select a highly customized Linux image, such as a firewall appliance. Microsoft assists you with these images, but the Linux vendor must be engaged to troubleshoot specific system-related problems. Microsoft may collaborate with the vendor for those issues.
  • Microsoft Support doesn't assist with basic Linux administration, design, architecture, or deployment of applications or solutions on Azure.
  • The ability to customize Linux is one of the hallmarks of the operating system. We encourage you to use a Linux solution that benefits your organization. However, the Linux vendor may not support some modifications such as custom kernels or modules. For vendor support, you may be required to use stock kernels or libraries for your image.
  • For some troubleshooting and performance tuning within Linux or applications, customers should directly contact the vendor of the supported Linux distribution or application.
  • Scenarios that are related to security aren't supported. These include but aren't limited to:
    • Compromised VMs
    • Security incident response investigations
    • Intrusion prevention assistance

Open-source technology support matrix

Microsoft may offer support for the following specific open-source technologies (subject to change):

  • Languages: PHP, Java, Python, and Node.JS
  • Database: MySQL
  • Web and application servers: Apache HTTP Server and Apache Tomcat
  • Frameworks: WordPress

Open-source technology support scope

Microsoft assists with supported open-source technologies. Customers who request support for design guidance or development assistance may be directed to forums or community support. Customers may also have to work directly with our Linux partners or software vendors for scenarios that Microsoft doesn't support. Examples include but aren't limited to:

  • Application development
  • Custom application troubleshooting
  • Custom code

Here are some of the support scenarios that Microsoft assists with:

  • Issues that occur during installation or configuration.
  • Deployment errors that occur when customers try to deploy applications to the Azure platform and services.
  • Runtime errors that occur when customers use the Azure platform and services.
  • Performance issues that affect applications built using the supported open-source technologies on the Azure platform and services.
