2、 clusters increases more and more. Enterprises, for their own development, have to acquire a large number of servers to expand the cluster. However, there are many drawbacks. For example, spending a lot of manpower and m

3、aterial resources, consuming large amout of capital, having long-term maintenance costs. Therefore, enterprises in the issue of whether to expand the private cluster are faced with a dilemma. With the development of tech

4、nology, the new ideas and technology of cloud computing are aware and endorsed by the people. As the use of water and electricity as easy to use computing resources is no longer a dream. In this context, many companies a

5、re considering using the cloud computing to expand their own clusters. While the scheduling problem is an important issue of both the cluster and cloud computing, researching the scheduling strategy of cluster expansion

6、under cloud computing, which can enhance the utilization of computing resources, reduce network load and improve the level of QoS to achieve the ultimate goal of reducing the computation time and cost, is significant. Fi

7、rstly, thip paper introduced the related technologies of cluster and cloud computing.Cluster technology included the basic conception of cluster, cluster characteristics, the conception of job scheduling and job scheduli

8、ng process. Meanwhile, discussed the job scheduling algorithms and the design principles of job scheduling algorithms and focused on analyzing the classic job scheduling algorithms. Cloud computing technology included th

9、e basic conception of cloud computing, the development of cloud computing, the basic framework of cloud computing, the characteristics of cloud computing and the main technologies of cloud computing.At last, the popular

10、cloud computing products in today’s market were described. Secondly, starting from the design requirements, the basic framework of the cluster expansion based on cloud computing was proposed. Cluster scheduling system an

11、d its working principles and process were discribed. Then, we introduced two simple scheduling strategies, and with the problems of the two algorithms and combined with the principle of scheduling algorithm, a new schedu
