摘要

针对边缘计算与内容分发网络（CDN）边缘节点如何实现资源协同的问题，文章提出了CDN缓存软件适配虚拟机和容器的技术与方法。通过对比分析物理机、容器和虚拟机3种部署模式下CDN的性能测试数据，评估了CDN虚拟化带来的性能损耗。容器模式性能损耗较小，其性能与物理机相当；而虚拟机模式性能损耗较大，其性能相当于物理机的75%左右。在性能标称值下，虚拟化后的CDN边缘节点可以释放中央处理器、内存和磁盘大部分资源，与边缘计算实现资源共享。

Abstract

Aiming at the problem of how edge computing and Content Delivery Network (CDN) edge nodes implementing the resource coordination

the technology and method of CDN cache software adapting to virtual machines and containers are proposed. By comparing and analyzing the performance test data of CDN in three deployment modes of physical machine

container and virtual machine

the performance loss caused by CDN virtualization is evaluated. The performance loss of the container mode is small

and its performance is comparable to the physical machine. The performance loss of the virtual machine mode is large

and its performance is equivalent to about 75%of the physical machine. According to the nominal value of performance

the virtualized CDN edge node can release most of the central processing unit

memory and disk resources

and achieve resource sharing with edge computing.
