METHODS AND SYSTEMS TO ASSESS EFFICIENT USAGE OF DATA-CENTER RESOURCES BY VIRTUAL MACHINES

摘要

Methods and systems that compute an efficiency coefficient of a set of virtual machines (“VMs”) running in a cloud-computing facility are described. The set of VMs may be a collection of VMs that form a VDC or the set of VMs may be a subset of a larger set of VMs that comprises a VDC. The efficiency coefficient is a metric that may be used to evaluate effective use of cloud-computing facility resources by the set of VMs. The efficiency coefficient is calculated based on ideal and actual cumulative cost of the set of VMs utilization of cloud-computing facility resources. As a result, the efficiency coefficient may also be used to assess cost effective use of cloud-computing facility resources by the set of VMs.

1. A method stored in one or more data-storage devices and executed using one or more processors of a computing environment to compute an efficiency coefficient of a set of virtual machines (“VMs”) that run in a physical data center, the method comprising:
computing an actual utilization cost of resources of the physical data center, for each VM; computing a total ideal cumulative cost distribution of the set of VMs based on the actual utilization costs of the VMs; sorting the set of VMs to generate a sorted set of VMs based on actual utilization cost associated with each VM, the sorted set of VMs arranged from lowest to highest associated utilization cost; computing an approximate total actual cumulative cost distribution of the sorted set of VMs based on the actual utilization cost associated with each VM; computing an efficiency coefficient based on the total ideal cumulative cost distribution and the approximate total actual utilization cost distribution; and generating an alert when the efficiency coefficient violates a minimum efficiency threshold.
