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.
