Problems solved by technology

In addition, migration time and migration energy consumption are only part of the cost of virtual machine migration, and other migration costs such as downtime have not been considered in existing methods, which is another shortcoming of existing virtual machine redeployment algorithms

Abstract

The invention discloses a cloud computing virtual machine deployment algorithm based on energy consumption, comprising a virtual machine initial deployment algorithm and a virtual machine re-deployment algorithm. The virtual machine initial deployment algorithm is a DRWMG (different resource with minimum gap) algorithm provided herein and includes: classifying newly arrived virtual machine requests into CPU (central processing unit) intensive requests, memory intensive requests and normal requests; applying different deployment strategies provided herein to the different types of virtual machine requests. The virtual machine initial deployment algorithm is an MCA (migration cost algorithm) provided herein, including: periodically re-deploying existing virtual machines according to virtualmachine migration overhead (migration time, migration energy consumption and downtime). Compared with existing virtual machine deployment algorithms, the DRWMG algorithm provided herein can reduce energy consumption of a cloud computing system and bring improved balance for the use of different resources of physical machines; the MCA provided herein can reduce the energy consumption of the cloud computing system and the migration overhead of virtual machines in the cloud computing system.

Description

technical field [0001] The invention relates to the field of virtual machine deployment in cloud computing, in particular to the problems of virtual machine initial deployment and virtual machine redeployment in cloud computing. Background technique [0002] Virtual machine deployment refers to finding a better mapping relationship in the current cloud computing system, that is, requesting N virtual machines V={vm 1 , vm 2 , vm 3 ,...vm N} Deploy to available M physical machines P={pm 1 ,pm 2 ,pm 3 ......,pm M} above. Virtual machine deployment is divided into two types: initial deployment and redeployment. Initial deployment refers to deploying a newly arrived virtual machine or a batch of virtual machine requests to physical machines; redeployment refers to readjusting the current virtual machine deployment of the cloud computing system. in order to achieve some optimization purpose. [0003] For the initial deployment of the virtual machine, the current method is...
