Linux in Azure
The endorsed Linux distributions are created and published by Linux partners for use in Azure environments. We recommend that you use an Endorsed Linux distribution because they're maintained by some of the most well-known Linux vendors in the world. You're welcome to bring your distributions of Linux into Azure. All distributions are welcome.

The Ubuntu lifecycle and release cadence
Action recommended: Canonical Ubuntu 18.04 LTS Reaching End of Standard Support on 31 May 2023
You can continue to use your existing VMs. However, security, feature, and maintenance updates will no longer be provided by Canonical and may leave your systems vulnerable. We recommend that you either migrate to the next Ubuntu LTS release or upgrade to Ubuntu Pro to gain access to extended security and maintenance from Canonical.
Upgrading to Ubuntu 20.04 LTS or Ubuntu 22.04
Transitioning to the latest operating system, such as Ubuntu 20.04 LTS or Ubuntu Pro 22.04 LTS, is important for performance, hardware enablement, and new technology benefits, and we recommend it for new instances. The transition may be a complex process for existing deployments. Therefore, it should be properly scoped and tested with your workloads. Although there's no direct upgrade path from Ubuntu 18.04 LTS to Ubuntu 22.04 LTS, you can directly upgrade to Ubuntu 20.04 LTS, and then to Ubuntu 22.04 LTS, or directly install Ubuntu 22.04 LTS. For more information, see the Ubuntu Server upgrade guide.
Ubuntu Pro – Extended Security Maintenance to 2028
Ubuntu Pro includes security patching for all Ubuntu packages because of Extended Security Maintenance (ESM) for Infrastructure and Applications and optional 24/7 phone and ticket support. Ubuntu Pro 18.04 LTS will remain fully supported until April 2028. Ubuntu Pro is available for free for personal and small-scale commercial users on up to five VMs and with transparent, per-machine pricing for enterprises. New VMs can be deployed with Ubuntu Pro from the Azure Marketplace. You can also upgrade existing VMs to Ubuntu Pro by purchasing from Canonical. For more information about Ubuntu 18.04 LTS End of Standard Support, see Ubuntu 18.04 LTS (Bionic Beaver) on Azure.
Linux support scope
Microsoft offers Linux support for endorsed Linux distributions in Azure. Depending on the scenario, the Linux vendor may have to be engaged.
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 you work with Azure support. Any consulting work may be referred to Microsoft Services if that type of guidance is needed.
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, some modifications may not be supported by the Linux vendor, such as custom kernel or modules. 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 about 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 doesn't assist in the design, architecture, or deployment of applications or solutions on Azure.
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, Node.JS
- Database: MySQL
- Web and application servers: Apache HTTP Server, Apache Tomcat
- Frameworks: WordPress
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. Customers may also have to work with our Linux partners or software vendors directly for scenarios that aren't supported by Microsoft. Examples include, but aren't limited to:
- Application development
- Troubleshooting custom applications
- Custom code
The following are some of the support scenarios that Microsoft will assist 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 that were built by using the supported open-source technologies on the Azure platform and services
