Window based state monitoring in cloud datacenter using VM concept

Cloud Computing provides solution to licensing, distribution, configuration, and operation of enterprise application associated with the traditional IT infrastructure. Thus to define Quality of Service (QoS) clients and service providers need to establish a Service Level Agreement (SLA). The main objective of service providers is to improve Customer Satisfaction Level (CSL). In this paper, we present a method to minimize the number of reports generated by adapting the method of Window based State Monitoring framework and thereby reporting only the continuous state violations. In previous works, the issue of SLA violation has not received thorough analysis. In this work, we will keep track of the violation in processing a user request and the CPU utilization during the completion of the task. This will play a major role in avoiding the performance degradation encountered by a VM. Another major contribution of this paper is committed to detailed analysis of the state of Cloud environments and datacenter resources with relevant energy consumption during the processing time of a user request.
