Energy-Aware Ant Colony Based Workload Placement in Clouds

With cloud computing becoming ubiquitous, cloud providers are starting to deploy increasing numbers of energy hungry data centers. Energy conservation then becomes essential, in order to decrease operation costs and increase the system reliability. One traditional approach to conserve energy in these environments is to perform workload (i.e., VM) consolidation. Thereby, workload is packed on the least number of physical machines in order to increase the resource utilization and thus be able to transition parts of the resources into a lower power state. However, most of the workload consolidation approaches applied until now are limited to a single resource (e.g., CPU) and rely on relatively simple greedy algorithms such as First-Fit Decreasing (FFD), which perform resource-dissipative workload placement.
