On September 12 , at the KVM Forum , the top global virtualization technology summit , the 2022 Global Enterprise KVM Open Source Contribution List was officially released. Tencent Cloud became the only cloud vendor in China to be shortlisted for six consecutive years.
As the key underlying technology of cloud computing, cloud vendors need to use KVM to virtualize physical machines to provide pooled computing power in the cloud. As the most important and authoritative conference in the KVM virtualization community, the KVM Open Source Contribution List of Global Enterprises released at the KVM Forum conference is an authoritative list for measuring the technical strength and open source contribution of enterprises in the KVM field.
Tencent Cloud contributed a total of 81 patches this year , and the only " core breakthrough " for Chinese companies . Over the past six years, Tencent Cloud has contributed 280 patches and 10 core breakthroughs , accounting for 20% of all core breakthroughs at the conference .
Tencent Cloud PEBS virtualization solution was rated as KVM annual core breakthrough
This year, Tencent Cloud's self-developed virtualization solution for accurate event sampling technology was rated as the annual core breakthrough of KVM .
This solution not only solves the problem of inaccurate matching between CPU hardware performance events and software codes, but also greatly reduces the sampling overhead of performance events and realizes code-level granularity. Data can be collected, performance can be analyzed, and bottlenecks can be optimized.
At present, the core framework of this solution has been contributed to the open source community and has been widely tested by the industry. Based on a series of self-developed virtualization technologies, developers on Tencent Cloud have been able to track business performance changes in depth through real quantified code-level hardware performance data, discover and solve performance bottlenecks, optimize overall business execution efficiency, and reduce overall computing power. cost.
In addition, Tencent Cloud also contributed two self-developed performance improvement solutions to the open source community. Among them, through the heuristic virtualization scheduling acceleration algorithm, the message delivery load performance in the large-scale virtual machine scenario is improved by 30% ; for IO -intensive services such as databases and general networks , the high-performance asynchronous IO framework ( io_uring ) is iterated, and the proposed The new asynchronous technology solution uringlet makes the response of key business and sensitive services more timely.
As the earliest cloud computing manufacturer in China to embrace KVM technology, Tencent Cloud has fully adopted KVM technology supported by the open source community since 2013 ; since 2014 , Tencent Cloud Cloud Server CVM has been produced based on KVM technology, and in the same year, it began to contribute achievements to the KVM community . Over the years, Tencent Cloud has successively contributed many cutting-edge technologies such as hot migration, virtualization layer consumption reduction, and lightweight virtualization technology to the open source community.
As the core module of the Linux kernel, technological breakthroughs in the field of KVM also mean that Chinese enterprises are moving upstream in the operating system community.
The relevant person in charge of Tencent Cloud said that in the future, Tencent Cloud will continue to embrace changes in the virtualization field. New technologies in the field, do a good job in the pre-research and accumulation of cutting-edge technologies, and unswervingly continue to make contributions to the virtualization open source community.
