The first community version of OpenCloudOS is officially released: a stable Linux distribution for enterprise servers

On January 26, OpenCloudOS, an open source operating system community, announced that the first official version, OpenCloudOS 8.5, was released.

As a reliable enterprise-level server Linux distribution, the new OpenCloudOS 8.5 version is based on the independent research and development design of the Linux kernel, and its core capabilities such as stability, security, compatibility and performance have been fully verified for a long time. Users can directly deploy and apply OpenCloudOS 8.5 to production systems, reducing users' system operating costs.

At the end of 2021, the mainstream operating system software CentOS8 in the industry has stopped maintenance, which makes a large number of users fall into security risks. The basic library and user-mode components of OpenCloudOS 8.5 are completely compatible with CentOS8, and through kernel-level optimization and enhancement, it provides users with better solutions than CentOS8.

It is understood that OpenCloudOS 8.5 has been running stably for more than 2 years in real business scenarios such as social networking, games, financial payment, AI, security, and big data. It has experienced long-term verification of tens of millions of nodes, and its availability is as high as 99.999%. Compared with CentOS7 and other open source community versions, OpenCloudOS 8.5 has a failure rate of more than 70% lower, and its performance is improved by more than 50% in typical business scenarios.

The current OpenCloudOS 8.5 version adopts an automatic and simple installation method that automatically partitions, formats, and installs the default software packages. The graphical environment is not installed by default. Compared with the traditional installation method, the operation is simpler and the process is faster. Users can also manually install on demand, which can meet the general needs of most server scenarios.

In terms of kernel, OpenCloudOS transplants the latest key features of the community, and optimizes functions and performance in combination with different business scenarios. Typical features include: container resource view isolation (cgroupfs), cloud native SLI, Monitor Buffer, ARM64 hot patch, Page Cache Limit Wait. On the whole, the kernel of OpenCloudOS can enjoy various new technologies and self-developed optimizations from the community while ensuring enterprise-level stability.

In terms of user-mode components, OpenCloudOS is expected to release the first version of V9 in early 2023. The V9 version will completely build and maintain all software packages from the Upstream community, independent of other vendors and downstream communities, and form a complete L1 community together with the independently evolved kernel. Then the community head manufacturers build the commercial version (ie L2 version) according to the L1 community, and after large-scale application verification in their own application scenarios, finally output a stable enterprise-level stable OpenCloudOS community version (ie L3 version, OpenCloudOS V9) ). While ensuring the reliable supply of open source OS software, based on the verification of a large number of application scenarios of leading manufacturers, the stability of the version is guaranteed to meet the needs of enterprise-level production.

In addition, the OpenCloudOS community will also invest a lot of resources to continuously cover the development and maintenance of the L1 to L3 communities and versions, and will also feed back relevant features to the L0 community to enhance the influence of the L0 upstream community. At the same time, all partners, developers, downstream manufacturers and users are welcome to derive their own commercial/free versions based on the stable version (L3 version) of OpenCloudOS, and jointly build a domestic operating system ecosystem and supply chain.

As a domestic open source operating system community, the technology accumulation of OpenCloudOS can be traced back to 2010. As one of the main initiators of the OpenCloudOS community, Tencent has developed its own server operating system TencentOS Server since 2010 based on its own business feature requirements, performance requirements and security requirements, based on massive business scenarios. In 2019, Tencent officially open sourced the TencentOS kernel.

OpenCloudOS, an open source operating system community jointly initiated by Tencent and its partners, is a completely neutral, fully open, secure, stable, and high-performance operating system and ecosystem. At the beginning of its establishment, OpenCloudOS decided to become a completely open and neutral open source community, and has confirmed the acceptance of community project donations through the TOC review of the Open Atom Open Source Foundation. In the future, under the trust and supervision of the foundation, OpenCloudOS will operate in a standard open source community model, and will be co-governed and built with community participating units.

OpenCloudOS has accumulated the advantages of many manufacturers in software and open source ecology, and inherited Tencent's more than 10 years of technical accumulation at the operating system and kernel level. It has solid support in cloud native, stability, performance, hardware support, etc., and can be equal Comprehensive support for all hardware platforms. With the official release of OpenCloudOS 8.5, OpenCloudOS will also provide stable and high-availability services for enterprises in more industries and application scenarios to meet the demanding workload requirements of the business.
