Systems and methods for colocating virtual machines on one or more physical infrastructure

摘要

This technology relates to a device and method for determining co-locatability of a plurality of virtual machines on one or more physical infrastructures. The plurality of virtual machines hosts a plurality of workloads. This involves identifying workloads which have high variability from the time series data and determining the workload capacity threshold of the identified workloads. Thereafter, the candidate workloads are selected among the identified workloads to colocate on a virtual machine based on the workload variability. After that, the total capacity required by each candidate workload pair to meet the service requirement is determined based on the workload capacity threshold. Then, an optimal sharing point of each workload of the pair with respect to the other workload of the pair is identified. Further, percentage compatibility of each workload pair is determined and finally, the candidate workloads are colocated based on the optimal sharing point and percentage compatibility.

1. A method for determining co-locatability of a plurality of virtual machines, the method comprising:
determining, by a virtual resource management computing device, a workload capacity threshold and a variability for a plurality of workloads on a corresponding plurality of virtual machines, wherein the determined variability is based at least in part on resource demand overlap data to indicate resource contention between the plurality of workloads on the corresponding plurality of virtual machines and the determined workload capacity threshold is based on a total workload capacity required by the plurality of virtual machines in a predetermined time period; selecting, by the virtual resource management computing device, at least two of the plurality of virtual machines for co-location based on the determined variability of the plurality of workloads on the corresponding plurality of virtual machines; determining, by the virtual resource management computing device, an optimal sharing point for the plurality of workloads corresponding to the at least two of the plurality of virtual machines, wherein the optimal sharing point is based on the total workload capacity required by the at least two of the plurality of virtual machines in the predetermined time period; and co-locating, by the virtual resource management computing device, the at least two of the plurality of virtual machines based on the determined optimal sharing point.
