Performance Analysis of Cloud Computing in Healthcare System Using Tandem Queues

Cloud technology is broadly supported by healthcare organizations worldwide. Throughout the previous few years, healthcare industries have recognized the potential of cloud computing architecture and how it can assistance them to give quality services to patients. The cloud technology has faster the way healthcare industry can use or share information crossways a network. This paper offering an e-health solution founded on healthcare information systems joined with cloud computing concept emphasis on medical information processing. Our proposed work based on public cloud and request management application has been proposed and analysed in terms of waiting time defined as Quality of Service criteria (QoS). The service of the public cloud has been modelled using queueing theory as two serially connected queues (Tandem Queues) M/M/s and single server retrial queue (SSRQ). The results obtained in our proposed model are considerably reducing the total waiting time of different class of units in the cloud system than the existing system and more utilization of service in cloud.
