Tencent CloudPEBS virtualizationProgram was ratedKVMCore Breakthrough of the Year

This year, the virtualization solution of the precise event sampling technology developed by Tencent Cloud was rated asKVMCore breakthrough of the year.

This solution, for the past virtualization environmentCPUThe pain point that software load data cannot be accurately quantified, not only solves the problemCPUThe problem of inaccurate matching of hardware performance events and software codes also greatly reduces the performance event sampling overhead, enabling code-level granular data collection, performance analysis, and bottleneck optimization.

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.30%;For databases, general networks, etc.IOIntensive business, iterative high-performance asynchronousIOframe(io_uring), proposed a new asynchronous technical solutionuringletmaking critical business and sensitive service response more timely.

As the earliest embrace in the country KVM Technology cloud computing vendor, Tencent Cloud from 2013 Full adoption of open source community-supported KVM technology;2014 Since 2009, Tencent Cloud Cloud Server CVM all based on KVM technical production, and in the same year began to KVM Community contributions. 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.

asLinuxcore modules of the kernel,KVMTechnological breakthroughs in the field also mean that Chinese companies 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 field of virtualization. On the one hand, it will solve various challenges encountered by Tencent Cloud online through continuous innovation and give feedback to the community. On the other hand, it will explore cloud computing. 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.
