Title

VERSIONING CLOUD COMPUTING TECHNOLOGIES: CENTRALIZED COMPUTING AND DISTRIBUTED COMPUTING

Abstract

This study concentrates on how to version cloud computing technologies and compare the two different operation models: centralized computing and distributed computing. With the classical model of the mechanism design, some interesting results are discovered. In the mechanism design, a cloud computing technology provider offers two service plans, and assumes that consumers select their service plans according to individual type. By involving queuing delay and system reliability in our study, we find that the results in centralized computing are consistent with those in prior studies in the mechanism design; however, the results in distributed computing are contrary to those. The phenomenon is caused by the factor that the level of service benefit in distributed computing is positively associated with the number of contributors. Also, we examine social welfare in centralized computing and indicate that the government has to understand the real benefits received by different group of consumers if a subsidy is provided.
