We provide a workload model for VM-hosted application based on grey system theory.The correlation analysis approach is used to determine the bottleneck resource.Relation between the workload and the bottleneck resource consumption is modeled.We apply our model to a video-on-demand system as a case study. The workload complexity of virtual machine-hosted (VM-hosted) applications widens the gap between resource demand and allocation, which could lead to either resource underutilization or application overload. This study addresses this issue by providing a correlation analysis approach and a novel workload model for VM-hosted applications. Based on the grey system theory, the correlation analysis approach is used to determine the bottleneck resource of a given VM-hosted application, and the Workload Conversion Model (WCM) constructs a quantitative relationship between the application workload and the consumption of the bottleneck resource by modeling the resource consumption. We apply our model to a video-on-demand system as a case study. The model identifies that the VM memory is a key bottleneck resource of the system, and a bimodal relationship exists between the workload and VM memory consumption. The experimental results also show that the precision of the WCM is high, with a relative percentage error less than 5% and a variance ratio less than 25%. |
