OVERVIEW
Deploy one Microsoft‑maintained Linux across your entire Azure environment
- Standardize on a single, Microsoft-backed platform for all your Linux workloads in Azure. Whether you are running scalable web apps, business-critical databases, AI solutions, or modern containerized applications, Azure Linux delivers consistency, single-vendor accountability and integration with key Azure services. Drive a unified Linux experience to simplify and streamline your Azure operations.
- Rely on the same supply chain security trusted by Microsoft services. Azure Linux can mitigate risks from third-party code tampering, minimize the attack surface, deliver a fast and predictable patching cycle, and provide a compliance path for regulated workloads. And with an immutable, container‑optimized Linux operating system for Azure Kubernetes Service (AKS), it provides a secure by default, minimal, and operationally consistent host OS.
- Improve the scalability and performance of your Linux estate in Azure. Azure Linux provides a lean OS with fast boot times, rapid service scaling, and a low overhead. Microsoft has been contributing to the Linux Kernel since 2009, and with Azure Linux developers and platform engineers can now experience predictable cloud native operations with quick Azure VM and AKS startup times.
- Drive cost efficiencies without compromise: Azure Linux is offered at no additional charge to Azure customers. With a minimal package footprint, it can reduce overhead, requiring less patching, lowering operational toil, and promoting a more efficient management of your IT estate. Help your organization lower TCO and scale Azure workloads more cost-effectively.
Use cases
Build and run a broad range of workloads on Azure Linux
Launch Azure Virtual Machines and lower your costs
Power business-critical workloads on Azure VMs with a Microsoft-backed Linux OS built for reliability. Azure Linux reduces operational complexity through a minimal footprint, a secure-by-default design, and single-vendor accountability.
Quickly scale out Linux apps on Azure Virtual Machine Scale Sets
Scale your workloads elastically on virtual machine scale sets with a Linux distro optimized for Azure. Azure Linux's minimal footprint and fast boot times accelerate provisioning cycles, reduce overhead, and keep operations consistent as your environment grows and contracts.
Deploy a lightweight Linux OS as a container host for AKS
Maintain AKS clusters with a container-optimized host OS engineered for Kubernetes and already powering millions of cores in production. Gain reliability and consistency from cloud to edge with AKS and Azure Arc-enabled AKS on Azure Linux minimal foundation to run container workloads.
Host AKS nodes on an immutable Linux distro
Deploy AKS worker nodes on Azure Container Linux—an immutable, container-optimized OS with a minimal attack surface, automated image updates, and mandatory access controls. One production-grade host OS designed to reduce complexity and strengthen your Kubernetes security posture.
