Performance Factors of Cloud Computing Data Centers Using M/G/m/m+r Queuing Systems
Cloud computing is a novel paradigm for the provision of computing infrastructure, which aims to shift the location of the computing infrastructure to the network in order to reduce the costs of management and maintenance of hardware and software resources. Cloud computing systems fundamentally provide access to large amounts of data. Resources provided by cloud computing systems hide a great deal of information from the user through virtualization. In this paper, the cloud data center is modeled as M/G/m/m+r queuing system with a single task arrivals and a task request buffer of finite capacity.
