Study on New Task Scheduling Strategy in Cloud Computing Environment Based on the Simulator CloudSim

Abstract

In this paper, the principle and mechanism of CloudSim is analyzed. The layered architecture of CloudSim is emphasized, including user code layer, cloud resource layer, cloud service layer, network layer, virtual machine service layer and user interface structure layer. Based on these works, taking the task scheduling in cloud environment as a research object, five task scheduling algorithms are proposed and are extended into CloudSim platform. Then a specific cloud simulation scene is deployed and five simulation experiments are carried out. The cloud computing simulation and the extension of task scheduling strategy in CloudSim become easily by the help of such works.
