US 8,949,848 B2 · Reducing usage of resource utilized by a virtual machine whose resource utilization is adversely affecting neighboring virtual machines

Abstract

A method, system and computer program product for managing resource utilization of virtual machines in a cloud computing environment. A cloud controller computes an index of the utilization of a resource by a virtual machine to determine its adverse impact on its neighboring virtual machine(s) that share the same resource. If the interference index is greater than a threshold, then the utilization of the resource by that virtual machine will be throttled or reduced provided that the servicing of its workload is not weighted at too high of a priority and that one or more of its neighboring virtual machines are not able to meet their service-level agreement requirements. In this manner, the adversely affected neighboring virtual machines may have its performance restored in meeting their service-level agreement requirements without having to add additional resources and/or be migrated to other areas of the cloud computing environment.

A method for managing resource utilization of virtual machines in a cloud computing environment, the method comprising:

monitoring a utilization of a resource for said virtual machines;
computing an index of utilization of said resource by a virtual machine to determine an adverse impact on one or more neighboring virtual machines that share said resource due to utilization of said resource by said virtual machine, wherein said index of utilization is represented by Y/(X+Y), wherein said X corresponds to an idle latency rate, wherein said idle latency rate is a latency rate when said virtual machine is idle, wherein said Y corresponds to a transaction latency rate, wherein said transaction latency rate is a latency rate said virtual machine is currently exhibiting for servicing its workload;
and reducing, by a processor, a usage of said resource by said virtual machine in response to said index exceeding a threshold value.

A computer program product embodied in a non-transitory computer readable storage medium for managing resource utilization of virtual machines in a cloud computing environment, the computer program product comprising the programming instructions for:

monitoring a utilization of a resource for said virtual machines;
computing an index of utilization of said resource by a virtual machine to determine an adverse impact on one or more neighboring virtual machines that share said resource due to utilization of said resource by said virtual machine, wherein said index of utilization is represented by Y/(X+Y), wherein said X corresponds to an idle latency rate, wherein said idle latency rate is a latency rate when said virtual machine is idle, wherein said Y corresponds to a transaction latency rate, wherein said transaction latency rate is a latency rate said virtual machine is currently exhibiting for servicing its workload;
and
reducing a usage of said resource by said virtual machine in response to said index exceeding a threshold value.
