After the CentOS shutdown, China’s open‑source Linux communities—deepin, OpenAnolis, openEuler, OpenCloudOS and OpenKylin—have formed five pillars that now dominate server, cloud, AI and desktop markets, with a projected 65% domestic OS share and a $30 billion market by 2025.
The article explains how OpenCloudOS, a fully self‑developed Linux operating system, attains industry‑leading six‑nine (99.9999%) availability by strengthening kernel quality, implementing comprehensive CI testing, managing vendor drivers, handling upstream bugs, and deploying automated crash analysis and rapid recovery mechanisms.
OpenCloudOS 9.0, the first fully self‑developed L3‑level cloud‑native operating system in China, combines independent kernel development, extensive software stack upgrades, and community‑driven validation to deliver high performance, security, and compatibility for cloud, big data, and AI workloads.
On 27 October 2022, ITU‑T approved the world’s first international standard (TD530‑R1) for a cloud‑computing energy‑consumption management and optimization platform, built on the OpenCloudOS “WuNeng” system that can cut data‑center power use by 5‑30 % with under 0.1 % performance loss, supporting global carbon‑neutral goals.
OpenCloudOS, a community‑driven Linux distribution, combines full‑stack hardware support, autonomous supply‑chain control, and extensive performance optimizations to deliver a high‑availability, cloud‑native server OS that rivals CentOS while offering 99.999% uptime and up to 50% performance gains in real‑world workloads.
OpenCloudOS, China’s first fully domestic server operating system, has transitioned from a mere open‑source user to a leading contributor, launching its L1 source community and L3 full‑package version, expanding ecosystem partnerships, and outlining a roadmap that promises future server, desktop, embedded, and edge OS releases.
OpenCloudOS, the newly released domestic open‑source server operating system, offers a full‑chain Chinese supply of kernel and software, supports both x86_64 and arm64, and has already been deployed on over ten million machines across key industries, signaling a major shift in China’s OS ecosystem.
