EulerOS. It is a Linux distribution developed by the Chinese technology giant Huawei for use in enterprise and cloud computing environments. Designed with a focus on high performance, security, and reliability, it serves as a foundational operating system for critical infrastructure. The distribution is named after the renowned mathematician Leonhard Euler and is positioned to compete in the server and cloud OS market alongside offerings like Red Hat Enterprise Linux and SUSE Linux Enterprise Server.

Overview

EulerOS is engineered to meet the demanding requirements of modern data centers and cloud computing platforms, providing a stable and secure base for deploying business applications. It is certified for compatibility with a wide range of hardware architectures, including x86-64 and ARM, and is optimized for use on Huawei's own server products like the FusionServer. The operating system forms a core component of Huawei's broader ecosystem, which includes the Kunpeng processor and the Ascend AI processor, aiming to provide an integrated solution from hardware to software.

Features

Key features of the distribution include enhanced security mechanisms such as the SELinux mandatory access control framework and comprehensive encryption support for data at rest and in transit. It offers high availability through integration with technologies like Corosync and Pacemaker for cluster management. For performance, it incorporates optimizations for virtualization platforms like KVM and container technologies including Docker and Kubernetes, facilitating efficient deployment in private cloud and hybrid cloud scenarios. The system also includes robust development tools and supports numerous programming languages and frameworks.

Versions and release history

The product line is primarily divided into two major version streams. EulerOS 2.0, based on the Linux kernel 4.19, is a long-term support release tailored for stable enterprise deployment, with service packs (SP) providing cumulative updates and security patches. EulerOS 3.0, utilizing a newer kernel, targets emerging technologies and hardware platforms. Major releases are strategically aligned with Huawei's product launches and industry events, with updates managed through a formal support lifecycle. The version history reflects a consistent focus on incorporating upstream Linux kernel advancements while maintaining stringent stability and certification standards.

Architecture and technical details

At its core, the system uses a standard Linux kernel that has been meticulously tuned and hardened for enterprise workloads. It supports multiple file systems, with XFS and ext4 being prominent for data storage. The software packaging and management are handled through the RPM Package Manager, with dependencies and updates managed via the YUM tool. For system initialization, it employs systemd, providing efficient service management and boot processes. The architecture is designed to be modular, allowing for streamlined installation of specific server roles, whether for web hosting, database management, or big data analytics platforms.

Development and community

Primary development is led by Huawei's in-house engineering teams, with contributions integrated from the wider open source software community. In 2019, Huawei announced it would open-source the distribution under the name openEuler, establishing an independent openEuler community to foster collaborative development around the operating system. This move, similar to strategies employed by The Fedora Project and openSUSE, aims to accelerate innovation and build an ecosystem of developers and vendors. The openEuler community hosts its own kernel, tools, and repositories, allowing other companies and individuals to participate in its evolution.

Adoption and use cases

Adoption is strongest within the Asia-Pacific region, particularly in China, where it is deployed by major telecommunications operators, financial institutions like the Industrial and Commercial Bank of China, and government agencies for its perceived security and local support. It is a preferred platform for running Huawei's cloud service, Huawei Cloud, and enterprise solutions such as FusionSphere. Use cases span running mission-critical SAP applications, hosting Oracle Database instances, powering artificial intelligence and machine learning workloads on Ascend processors, and serving as the host OS for large-scale Kubernetes clusters in containerized environments.
