Modeling overhead for a plurality of virtualization technologies in a computer system

A method comprising:

• providing a plurality of overhead profiles on a non-transitory computer readable medium, each overhead profile being based on measures of overhead for a given virtualization technology on a given computer system,
• defining an allocation of tasks on one or more virtual machines on a target computer system that is using a target virtualization technology,
• identifying a select overhead profile of the plurality of overhead profiles corresponding to the target computer system and target virtualization technology, and
• determining, by a processing device, an overhead associated with the target computer system based on the select overhead profile and a plurality of operating parameters associated with the tasks and the target computer system
• wherein the plurality of overhead profiles includes profiles based on a plurality of virtualization technologies, each virtualization technology providing a different technique for dividing resources of a computer into multiple execution environments.

A method comprising:

• for each virtualization technology of a plurality of virtualization technologies:
• implementing the virtualization technology on a physical computer system having a first configuration,
• partitioning the computer system into a plurality of groups of virtual machines using the virtualization technology, wherein each group contains a different number of virtual machines,
• for each group of virtual machines, determining a measure of overhead for each utilization of a plurality of utilizations, and
• providing an overhead profile for the virtualization technology based on the measures of overhead for each group of virtual machines and each utilization to facilitate determining a measure of overhead for a target system using the virtualization technology on a similar computer system having the first configuration,
• wherein each virtualization technology of the plurality of virtualization technologies provides a different technique for partitioning the computer system into the plurality of numbers of virtual machines.

A non-transitory computer readable medium that includes a computer program that, when executed, causes a processor to:

• define an allocation of tasks on one or more virtual machines on a target computer system that is using a target virtualization technology of a plurality of virtualization technologies, wherein each virtualization technology provides a different technique for dividing resources of the target computer system into multiple virtual machines,
• identify a select overhead profile of a plurality of overhead profiles corresponding to the target computer system and target virtualization technology, each overhead profile of the plurality of overhead profiles being based on measures of overhead for each of the plurality of virtualization technologies on a given computer system,
• determine an overhead associated with the target computer system based on the select overhead profile and a plurality of operating parameters associated with the tasks and the target computer system, and
• create one or more reports based on the overhead.

A non-transitory computer readable medium that includes a computer program that, when executed, causes a processor to:

• receive an identification of a computer system having a first configuration,
• determine a measure of overhead for each utilization of a plurality of utilizations for each of a number of virtual machines on the computer system created by each virtualization technology of a plurality of virtualization technologies, and
• provide an overhead profile based on the measures of overhead for each number of virtual machines and each utilization to facilitate determining a measure of overhead for a target system using the virtualization technology on a similar computer system having the first configuration,
• wherein each virtualization technology provides a different technique for dividing resources of the computer system into multiple execution environments.
