Hierarchical stochastic models for performance, availability, and power consumption analysis of iaaS clouds
, Article IEEE Transactions on Cloud Computing ; 2017 ; 21687161 (ISSN) ; Entezari Maleki, R ; Rashidi, L ; Trivedi, K. S ; Ardagna, D ; Movaghar, A ; Sharif University of Technology
Abstract
Infrastructure as a Service (IaaS) is one of the most significant and fastest growing fields in cloud computing. To efficiently use the resources of an IaaS cloud, several important factors such as performance, availability, and power consumption need to be considered and evaluated carefully. Evaluation of these metrics is essential for cost-benefit prediction and quantification of different strategies which can be applied to cloud management. In this paper, analytical models based on Stochastic Reward Nets (SRNs) are proposed to model and evaluate an IaaS cloud system at different levels. To achieve this, an SRN is initially presented to model a group of physical machines which are...
