Abstract
We characterize the effects of asymmetries, dynamics, and failures when introduced into a cloud computing simulator, which had previously been characterized under static, homogeneous configurations with various patterns of demand and supply. We aim to determine whether injecting these new factors into the cloud simulator causes fundamental shifts in macroscopic behavior and user experience. We find that introducing asymmetries, dynamics, and failures into the cloud simulator does not induce fundamental shifts in the factors driving simulator behavior, but these new parameters do exhibit interactions with the main driving factors, and with each other. Our findings suggest that a previous study, using the cloud simulator to compare virtual-machine placement algorithms, need not be extended to consider the effects of asymmetries, dynamics, and failures. These findings also increase our confidence in results from the previous study.Citation
