Linux in Azure

The endorsed Linux distributions are created and published by Linux partners for use in Azure environments. It's recommended to use an Endorsed Linux distribution because they are maintained by some of the most well-known Linux vendors in the world. However, you are welcome to bring your distributions of Linux into Azure. All distributions are welcome.

Linux support scope

Microsoft offers Linux support for endorsed Linux distributions in Azure. The Linux vendor may need to be engaged depending on the scenario.

  • Microsoft will assist you with commercially viable support in the form of break-fix issues for Linux. The Linux vendor may have to be engaged by the customer to troubleshoot specific system-related problems. Microsoft may be able to collaborate with the vendor for those issues.
  • Have your Linux administrator engaged when working with Azure support. Any consulting work may be referred to Microsoft Services if that type of guidance is needed.
  • Customizing Linux is one of the hallmarks of the operating system. While we encourage you to use a Linux solution that benefits your organization, some modifications, such as custom kernel or modules, may not be supported by the Linux vendor. For vendor support, you may be required to use stock kernels or libraries for your image. For more information, contact your Linux vendor.
  • Microsoft may provide recommendations regarding Azure platform and services. For some troubleshooting and performance tuning within Linux or applications, the customer should directly contact the vendor of the supported Linux distribution or application.
  • Microsoft Support does not assist in the design, architecture, or deployment of applications or solutions on Azure.
  • Scenarios that are related to security are not supported. This includes, but is not limited to, compromised virtual machines, security forensics, DDoS, or intrusion-prevention assistance.

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

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

Open source technology support scope

Microsoft will assist with supported open-source technologies. Customers who request support for design guidance or development assistance may be directed to forums or community support.

Examples include, but are not limited to, application development, troubleshooting custom applications, and custom code.

Here are some of the support scenarios that Microsoft will assist with:

  • Issues that are encountered during installation or configuration.
  • Deployment errors that are encountered when customers try to deploy applications to the Azure platform and services.
  • Runtime errors when customers use the Azure platform and services.
