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.
