One way to conserve energy in cloud data centers is to transition idle servers into a power saving state during periods of low utilization. Dynamic Virtual Machine (VM) Consolidation (VMC) algorithms are proposed to create idle times by periodically repacking VMs on the least number of Physical Machines (PMs). Existing works mostly apply VMC on top of centralized, hierarchical, or ring-based system topologies which result in poor scalability and/or packing efficiency with increasing number of PMs and VMs.
