EulerOS represents a proprietary Linux distribution created by Huawei, built upon Red Hat Enterprise Linux and tailored for deployment in server and cloud infrastructure. Its community-driven open-source variant, known as openEuler, was introduced on Gitee in 2020. By November 2021, Huawei contributed the openEuler source code to the OpenAtom Foundation, transitioning it into a foundation-managed open-source initiative.
In September 2021, Huawei unveiled a new programming language aimed at both EulerOS and HarmonyOS. The initial long-term support edition, openEuler 20.03 LTS, was released in March 2020.
The openEuler 21.09 update brought the introduction of EulerFS, a newly developed file system, accompanied by a kernel enhancement featuring a multi-kernel architecture akin to that of HarmonyOS and OpenHarmony. This design combines RTOS and Linux kernels to support UniProton RTOS as well as the kubeOS container-based operating system.
EulerOS is compatible with essential enterprise software such as the Apache HTTP Server, bolstering its suitability for cloud services and server environments.
KunLun Mission Critical Server
Running on Huawei’s KunLun Mission Critical Server, EulerOS 2.0 achieved certification in 2019 for compliance with the Single UNIX Specification (UNIX 03); this certification remained valid until September 2022. The EulerOS/KunLun platform allows hot-swapping of CPU and memory components without requiring system downtime, thereby improving availability for mission-critical business applications.
Core technologies are shared between EulerOS/openEuler and Huawei’s mobile operating system, HarmonyOS. These include the BiSheng Compiler, distributed DSoftBus framework, OpenHarmony’s distributed file system (HMDFS), the EROFS read-only file system, and native HAP packaging format. Huawei intends to enhance integration by further unifying these elements across its operating systems.
NestOS
Introduced in November 2021, NestOS is a cloud-centric operating system derived from the open-source EulerOS platform. It extends EulerOS functionalities to better serve cloud workloads while retaining compatibility within the existing ecosystem. In October 2022, the openEuler community released an updated NestOS version based on openEuler 22.09, which includes the nestos-assembler container image, optimized Kubernetes deployment, and improvements to its OpenStack integration aimed at boosting cloud infrastructure efficiency.
