    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.
