Development of a Model and Algorithms for Servicing Traffic in a Cloud Computing System

摘要

There is a serious variance in the requirements for the provided resource in cloud systems. Also it's needed to quickly process incoming requests and maintain the proper level of quality of service. All these factors cause difficulties for cloud providers. The proposed analytical model is designed to process requests for a cloud computing system in the Processor Sharing (PS) service mode. It allows us to solve mentioned problems. In this work, the flow of service requests is described by the Poisson model which is a special case of the Engset model. The proposed model and the results of its analysis can be used to evaluate the main characteristics of cloud systems performance.
