Modeling Heterogeneous Virtual Machines on IaaS Data Centers
Bin Wang, Xiaolin Chang, Jiqiang Liu · IEEE Communications Letters · 2015
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.
