Problems solved by technology

Due to the heterogeneity of virtual machine resource requests and the different host resource provisioning capabilities, different virtual machine placement strategies will result in different host energy consumption.
However, studies have shown that idle physical hosts still consume more than half of the energy consumed by fully loaded hosts

Abstract

The invention belongs to the technical field of cloud computing, and discloses a virtual machine placement method and device based on harmony search, equipment and a storage medium. The method comprises the following steps: acquiring a virtual machine set and a physical host set to be placed, and establishing a harmony memory bank according to the virtual machine set and the physical host set; generating a new harmony according to a preset harmony generation condition; performing fitness calculation on various harmonics and new harmonics in the harmonics memory bank, and updating the harmonicsin the harmonics memory bank according to a calculation result; determining a target harmony with the maximum fitness value according to the updating result, and taking tone information of the targetharmony as an optimal solution for virtual machine placement; and placing the virtual machines in the virtual machine set into physical hosts corresponding to the physical host set according to the virtual machine placement optimal solution. Under the condition that the resource utilization rate and the energy consumption of the physical host are constrained, low-energy-consumption optimization of virtual machine placement is formed by generating a new harmony, namely a new placement scheme.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, and in particular to a harmony search-based virtual machine placement method, device, device and storage medium. Background technique [0002] The problem of high energy consumption in cloud computing data centers has become more and more prominent, and the energy consumption of hosts and cooling systems has constituted the main part of the operating costs of data centers. Inefficient utilization of physical hosts increases the energy costs of the data center. Through virtualization technology, several virtual machines can be virtualized on one physical host, and user applications can be executed in units of virtual machines. How to place virtual machines on the host becomes a key factor that ultimately affects the energy consumption of the host. The virtual machine placement problem is the process of placing a collection of virtual machines onto a physical host. Due to the het...
