Cut operating system (OS) costs while running secure, consistent workloads on Azure. Effective June 2, 2026, Microsoft made Azure Linux available in public preview.
Summary
- Microsoft released Azure Linux, a cloud-optimized Linux distribution built for Azure, in public preview
- Azure Linux eliminates OS licensing overhead while maintaining enterprise-grade support
- A hardened, secure-by-default architecture and a Microsoft-managed supply chain help reduce risk
- Coverage spans virtual machines (VMs), containers, and cloud-native workloads
- Azure Linux suits organizations standardizing Linux workloads on Azure
- Your teams can start evaluating Azure Linux in the public preview now
What is changing?
Microsoft has introduced Azure Linux as a public preview for organizations running on Azure. It is a Microsoft-built Linux distribution optimized for Azure across VMs, containers, and cloud-native workloads. Microsoft positions it as a single, enterprise-grade Linux platform that reduces fragmentation and standardizes your environments.
At this stage, Azure Linux is in preview, not general availability. Microsoft has also stated that additional Secure Boot certificate check capabilities are planned for a future release.
What is Azure Linux?
Azure Linux is a cloud-optimized Linux distribution that Microsoft builds and maintains specifically for Azure. It provides a secure, consistent foundation for running workloads on virtual machines, containers, and managed services. Microsoft controls the build and the software supply chain, which supports predictable updates and compliance.
Within the Microsoft Azure ecosystem, Azure Linux serves as a first-party operating system for Azure-based solutions. On the licensing side, it removes separate OS licensing overhead, while Microsoft continues to provide enterprise-grade support.
Customer benefits at a glance
- Lower total cost of ownership through no separate OS licensing fees
- Reduced risk from a secure-by-default, Microsoft-managed platform
- Simpler compliance, backed by a controlled software supply chain
- Less operational complexity by standardizing on one Linux platform
- Faster deployment of modern applications across your environments
Key capabilities
- Hardened, secure-by-default OS with predictable updates
- Microsoft-managed software supply chain
- Faster boot times and improved networking tuned for Azure
- Infrastructure-level performance tuning for Azure
- Support for VMs, containers, and cloud-native and artificial intelligence (AI) workloads
Why Azure Linux is relevant now
Many organizations run mixed Linux estates with separate licenses, update cycles, and support contracts. This increases cost, operational effort, and security risk. Azure Linux lets your organization standardize on one Microsoft-supported platform, which reduces fragmentation and increases consistency. The secure-by-default design and managed supply chain strengthen compliance and control. Because Microsoft removes separate OS licensing overhead, teams gain clearer, more predictable cost planning for Azure workloads.
What organizations should do now
- Review which Azure workloads currently run on third-party Linux distributions
- Identify the OS licensing and support costs tied to those workloads
- Validate Azure Linux against application, security, and compliance requirements in a test environment
- Pilot Azure Linux on at least one non-production workload during the preview
- Monitor Microsoft updates, including the planned Secure Boot certificate check capabilities
- Plan a standardization roadmap before moving from preview to production
