Abstract

The invention discloses an IAAS virtual machine dynamic migration method balancing energy consumption and service quality. The IAAS virtual machine dynamic migration method balancing energy consumption and service quality is applied to a deployment scheme formed by deploying N virtual machines to M hosts. The IAAS virtual machine dynamic migration method is characterized by comprising the following steps that (1) a variation of a total load per unit cycle is judged, and a step (2) is executed when the load variation is not zero; (2) j is set equal to one; (3) energy consumption of the jth host in the current cycle is obtained; (4) energy consumption of the jth host is compared with a set energy consumption range, if the energy consumption of the jth host is not within the set energy consumption range, a step (5) is executed before a deployment scheme is obtained again according to a virtual machine dynamic migration model, and if not, the step (5) is executed directly; (5) j+1 is assigned to j, and the step (3) is executed again until j is equal to M. The IAAS virtual machine dynamic migration method can guarantee service quality for a user and reduce energy consumption of a data center at the same time, thereby improving the utilization rate of virtual cloud service resources and management efficiency of cloud service providers and avoiding resource waste.

Description

technical field [0001] The invention is applied in the field of cloud computing and relates to a resource allocation technology of a data center, specifically an IAAS virtual machine dynamic migration method that balances energy consumption and service quality. Background technique [0002] With the rapid development of Internet technology, cloud computing has established a new type of information service environment, enabling users to obtain various types of virtual cloud service resources on demand. However, with the rapid increase in user demand for virtual cloud service resources, more and more cloud computing data centers have emerged in various places. While providing convenience to users, these data centers also increase a lot of energy consumption and generate a lot of CO2. [0003] At present, dynamic migration of virtual cloud service resources, reducing the number of low-load hosts, and improving the utilization of data center hosts are one of the effective ideas...
