Abstract In the world of big data, cloud computing become more and more popular, but it takes high expense for enterprises when testing the cloud applicaiton in a real environment. Therefore, a simulator is needed which can be tested repeatedly and adapted to the different deploying algorithms.
This paper will take CloudSim as our cloud computing simulation platform to simulate the cloud computing environment, and realize an allocation policy for MDC, which is compared to the minimal workload first allocation policy and minimal fittest allocation policy.
This paper is organized as follows:
In section 1, we bring forward the background and situation. In section 2, we introduce the relevant technologies using in this paper, such as the concept and category of cloud, virtualization and brief of MDC. Section 3 depicts the three virtual machine allocation policies and their migrate algorithms in detail. Section 4 is the establishment of simulation platform and the analysis of the experiment. According to the analysis of result, we compare the advantages and disadvantages among the three virtual machine allocation policies. Section 5 is the conclusion and prospect of the paper.
