Abstract

A system and method of selectively consolidating applications on a machine comprises retrieving resource utilization data for a plurality of applications over a plurality of cycles for designated resource dimensions. A representative utilization profile is calculated on each application for each resource dimension. Load mean and variance values of the applications are calculated for each resource dimension. Each application is assigned to a class based the mean and variance values. A consolidation algorithm is computed on each application for each resource dimension to determine if resource consumption of the consolidated applications potentially exceed an available capacity in a machine.
