Modeling heterogeneous virtual machines on iaa s data centers
- 1. Modeling Heterogeneous Virtual Machines on IaaS Data Centers Abstract: This letter considers the IaaS data center where tenant tasks are different in terms of the number of requested physical cores, leading to heterogeneous virtual machines (VMs). We develop a novel analytical model to evaluate the performance of heterogeneous VMs on the same physical machine by applying the Continuous Time Markov Chain. Existing System: Accurate performance evaluation of IaaS cloud is one of the critical issues that IaaS providers must address. Analytical modeling is an effective performance evaluation approach. Stochastic models, seeing and references therein, have been proposed for evaluating the performance of IaaS data centers by assuming all VMs/servers are homogeneous. In actual cloud data centers, the capacities and/or types of physical and/or virtual resources requested by tenants may be different, leading to VM heterogeneity. IaaS providers are being providing various VMs to meet tenants’ diverse service requests. Large scale is also a fact of life in IaaS data centers. Recently, some authors proposed scalable modeling

Note that an approximately accurate monolithic model of a PM is a necessary prerequisite for the effectiveness of these interacting stochastic model approaches. Proposed System: The state transition rules and the formulas for computing performance measures are described in detail. These computing formulas help defining various SLAs and revealing practical insights into capacity planning for cloud data centers. Extensive numerical analysis experiments and simulations are performed. The experiment results validate the model approximation accuracy.
