The Queueing Theory in Cloud Computing to Reduce the Waiting Time
T. Sai Sowjanya · 2011
Cloud computing is an emerging technology of business computing and it is becoming a development trend(r).. The process of entering into the cloud is generally in the form of queue, so that each user need to wait until the current user is being served. In the system, each Cloud Computing User (CCU) requests Cloud Computing Service Provider (CCSP) to use the resources, if CCU(cloud computing user) finds that the server is busy then the user has to wait till the current user completes the job which leads to more queue length and increased waiting time. So to solve this problem, it is the work of CCSP's to provide service to users with less waiting time otherwise there is a chance that the user might be leaving from queue. CCSP's can use multiple servers for reducing queue length and waiting time. In this paper, we have shown how the queuing model, M/M/S model is used for multiple servers to reduce the mean queue length and waiting time.
