TECHNIQUES FOR WORKLOAD BALANCING AMONG A PLURALITY OF PHYSICAL MACHINES
First Claim
1. A method for workload balancing among a plurality of physical machines hosting a plurality of virtual machines (VMs), comprising:
- periodically measuring a utilization of each hardware resource in each of the plurality of physical machines;
computing a resource utilization score for each hardware resource based on its respective measured utilization;
computing a total physical machine utilization score for each physical machine based on the computed resource utilization scores of its respective resources; and
upon reception of a client request corresponding to a software application, selecting one physical machine of the plurality of physical machines to serve the client request, wherein the selection is based on the computed total physical machine utilization.
