Multi Criteria Decision Making for Resource Management in Virtualized Environment

Abstract

The workload in each node changes dynamically over time in large-scale data centers, so the workload in some machines may exceeds the threshold, which not only can’t guarantee the quality of service requirements (QOS), may also waste resources. One of the key benefits of virtualization is reassignment of a virtual machine to another physical host can be done when resource shortage or poor utilization conditions occurs in host. In this paper, we proposed the decision support system for resource management in Virtualized Data Center (VDC) based on the integrated approach of Analytical Hierarchy Process (AHP) and the Preference Ranking Organization METHod for Enrichment Evaluations (PROMETHEE). In this case, AHP is used to assign weights to the criteria to be used in selection phase, while PROMETHEE is employed to determine the priorities of the alternatives.
