EulerOS

EulerOS is a commercial Linux distribution developed by Huawei based on Red Hat Enterprise Linux[2] to provide an operating system for server and cloud environments.[3][4] Its open-source community version is known as openEuler, a multi-kernel project incubated and operated by the OpenAtom Foundation; the source code of openEuler was released by Huawei at Gitee on December 31. EulerOS itself officially launched September 23, 2021[5] alongside to openEuler publicly on September 25, 2021.[6][7][8]

openEuler 21.09 version launched with new file system called EulerFS, also a kernel upgrade that is organized similar to classic HarmonyOS and OpenHarmony multi-kernel architecture that carries both RTOS kernel and Linux kernel on October 1, 2021. Also, the operating system supports, UniProton RTOS kernel and kubeOS containerised OS.[9]

openEuler became an open-source project operated by OpenAtom Foundation after Huawei donated the source code of openEuler to the foundation on November 9, 2021.[10][11]

EulerOS includes Apache HTTP Server which is known as Apache, as part of its supported tools on the platform.[12]

KunLun Mission Critical Server

edit

EulerOS 2.0, running on the Huawei KunLun Mission Critical Server, was certified to conform to The Open Group's UNIX 03 standard, however the certification expired in September 2022.[13]

EulerOS/KunLun allows replacing central processing unit board modules and memory modules without stopping the OS. Hot swapping of CPU and memory is provided by EulerOS.[14]

Code shared with HarmonyOS and OpenHarmony

edit

EulerOS with openEuler shares technology with Huawei's mobile operating system, HarmonyOS including BiSheng Compiler, distributed DSoftBus technology, OpenHarmony distributed file system (HMDFS), EROFS read-only file system and native HAP file format. Huawei plans to unify additional components between both OSes.[15][16]

NestOS

edit

In November 2021, NestOS, an operating system based on open source EulerOS was launched. It incorporates the features of EulerOS, enhancing its capabilities in the cloud to cater to specific needs. NestOS, while maintaining the EulerOS ecology, brings its own features for various applications.[17]

In October 2022, the openEuler community updated the NestOS operating system to the new version based on the openEuler 22.09 version that include enhanced features to the system with nestos-assembler container image, optimized K8S, and improvements to its OpenStack system.[18]
