Liu Ch · Computer and Digital Engineering · 2015
This paper introduced the architecture,core class libraries and applications of the Cloud Computing simulation toolkit— Cloudsim.Besides we found a mathematical model for virtual machine placement problem,and introduced a new approximation algorithm CF to solve it.This algorithm was compared with Cloudsim built-in algorithm FCFS.Simulations were finished on Cloudsim.The result showed that cloud computing resource utilization can be effectively improved by optimizing the virtual machine placement algorithm.And Cloudsim can efficiently support extended simulation and realize the simulation of virtual machine placement algorithm.
