openEuler: The Enterprise Linux You Haven't Heard Of

What is openEuler

openEuler is an enterprise Linux distribution originally developed by Huawei, now governed by the OpenAtom Foundation — the same Chinese open source foundation that hosts OpenHarmony. Initially based on Red Hat Enterprise Linux, openEuler has evolved into an independent distribution targeting servers, cloud computing, edge devices, and embedded systems.

As of late 2025, openEuler has crossed 16 million installations and supports six processor architectures: AArch64 (including Huawei Kunpeng), x86-64, 32-bit ARM, IA-32, RISC-V, and LoongArch.

If you work in global infrastructure, you need to understand openEuler — not because you will necessarily run it, but because it is shaping how a significant portion of the world’s computing infrastructure operates.

The history

The timeline tells the story of a commercial Linux going open:

• 2019: EulerOS released as Huawei’s commercial Linux distribution, based on RHEL
• January 2020: Source code released on Gitee as openEuler — community edition launched
• March 2020: openEuler 20.03 LTS — first Long Term Support release
• November 2021: Huawei donates openEuler source code to the OpenAtom Foundation, making it vendor-neutral
• October 2021: openEuler 21.09 introduces EulerFS (a new filesystem) and multi-kernel architecture (Linux + UniProton RTOS)
• September 2025: openEuler 25.09 — latest release
• November 2025: 16 million installation milestone announced at the OS Conference and openEuler Summit

The donation to OpenAtom Foundation is the key inflection point. It moved openEuler from a Huawei product to a community-governed project — similar to how Red Hat contributed to CentOS or how Oracle funds Unbreakable Linux.

Why openEuler matters for platform engineers

Multi-architecture support from day one

Most enterprise Linux distributions treat x86-64 as the primary target and ARM as an afterthought. openEuler was designed for Huawei’s Kunpeng ARM processors from the beginning, which means ARM is a first-class citizen — not a port.

This matters as ARM workloads grow in cloud and edge:

• AWS Graviton instances run on ARM
• Ampere Altra processors power Oracle Cloud and Azure ARM VMs
• Edge and IoT devices increasingly use ARM and RISC-V

openEuler’s multi-architecture parity means the same distribution runs on x86 servers, ARM edge nodes, and RISC-V development boards — with consistent tooling and package availability.

RISC-V readiness

openEuler is one of the few enterprise-grade distributions with genuine RISC-V support. As RISC-V moves from academic curiosity to commercial deployment (RISC-V laptop chips, datacenter accelerators), having a production-quality Linux that runs on the architecture becomes strategically important.

Multi-kernel architecture

openEuler 21.09 introduced a unique multi-kernel design: the standard Linux kernel runs alongside UniProton, a microkernel RTOS. This allows a single openEuler deployment to handle both general-purpose Linux workloads and real-time tasks — critical for industrial edge computing, autonomous systems, and telecom infrastructure.

This is architecturally different from running a standard Linux with PREEMPT_RT patches. It is a true multi-kernel system where latency-sensitive tasks run on the RTOS while the Linux kernel handles everything else.

Kubernetes and cloud native

openEuler includes kubeOS — a containerized, immutable OS variant designed specifically for Kubernetes nodes. Think of it as openEuler’s answer to Flatcar Container Linux or Bottlerocket:

• Minimal footprint optimized for container workloads
• Atomic updates to prevent drift
• Kubernetes-native lifecycle management
• Reduced attack surface compared to full-featured distributions

For teams building Kubernetes platforms, kubeOS provides an alternative node OS that is worth evaluating — especially in environments where Huawei hardware is prevalent.

The ecosystem

openEuler’s ecosystem is broader than most Western engineers realize:

OS vendors shipping openEuler-based distributions:

• SUSE Liberty Linux (supports openEuler migration paths)
• Various Chinese vendors: TurboLinux, UnionTech, Kylin, KylinSec
• The distribution powers significant government and enterprise infrastructure in China

Foundation memberships:

• Linux Foundation (Associate Member)
• OpenInfra Foundation
• OpenChain Project
• RISC-V International
• LF AI & Data Foundation
• Zephyr Project
• Linaro

These memberships signal that openEuler is not operating in isolation — it is actively participating in the global open source ecosystem.

How openEuler compares to other enterprise Linux distributions

The key differentiator is the multi-architecture strategy and the multi-kernel design. No other enterprise distribution offers a built-in RTOS alongside the Linux kernel.

Should you evaluate openEuler

Consider openEuler if:

• You operate infrastructure on Huawei Kunpeng or other ARM processors
• You need RISC-V support in a production-grade distribution
• You are building edge or industrial IoT platforms that need real-time capabilities
• You want a Kubernetes node OS with kubeOS
• You are working on projects in China or Asia where openEuler is the standard

Stick with your current distribution if:

• Your infrastructure is purely x86 on Western cloud providers
• Your vendor support contracts are tied to RHEL, Ubuntu, or SUSE
• You need certifications (SOC 2, FedRAMP) that are currently only available for Western distributions
• Your team has no Chinese language capability for community support

Getting started

# Download the latest ISO
# https://www.openeuler.org/en/download/

# Or pull the container image
docker pull openeuler/openeuler:25.09

# Verify the installation
cat /etc/openEuler-release

# Install packages with dnf (familiar for RHEL users)
sudo dnf install nginx kubernetes-client

openEuler uses dnf as its package manager — familiar territory for anyone who has worked with RHEL or Fedora. The transition from a RHEL-based workflow is minimal.

The bigger picture

openEuler represents a broader trend: the diversification of enterprise Linux beyond Western vendors. As digital sovereignty becomes a priority globally — not just in the EU with the Cyber Resilience Act but in China, India, and elsewhere — sovereign operating systems become strategic infrastructure.

Whether or not you ever run openEuler, understanding its trajectory helps you understand where global infrastructure is heading. The days of a single enterprise Linux dominating everywhere are ending. Multi-distribution, multi-architecture platforms are the future.
