Virtual machine automatic migration decision-making method based on user experience in multi-cloud environment

Abstract

The invention discloses a virtual machine automatic migration decision-making method based on user experience in a multi-cloud environment, and belongs to the technical field of computers. The virtual machine automatic migration decision-making method comprises the steps that whether static migration exists in a multi-cloud cascade environment or not is judged, if the static migration can be used for completing migration of a virtual machine, the static migration is used, otherwise, dynamic migration is used, and the access time period of a user for accessing the virtual machine on a multi-cloud platform is predicted; virtual machine parameters and performance data of physical nodes are collected, the access time period, the virtual machine parameters and the performance data of the physical nodes are used for obtaining a fuzzy consistency judgment matrix of the FAHP, the weights of domain sub-module parameters in a weight equation are solved according to the fuzzy consistency matrix, and according to the solved weights of the domain sub-module parameters, the FAHP is obtained. And determining a migration sequence of the virtual machines according to a high-low sequence of the weights, and selecting important virtual machines for preferential migration according to the priorities. The automatic migration decision-making method can be used for automatically screening migration nodes of the virtual machine.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a decision-making method for automatic migration of a virtual machine based on user experience in a multi-cloud environment. Background technique [0002] Data centers have become the infrastructure of all walks of life, from data centers providing business support for small and medium-sized enterprises to IDCs of large companies, these data centers rely on huge hardware infrastructure and complex software for management. Events such as service interruptions often occur in major data centers at home and abroad. Service interruptions of faulty nodes may often affect normal operating nodes. During service interruptions, data center administrators often develop codes to restore services. Stability of cloud services Quality and customer satisfaction have become specific indicators for QOS evaluation. [0003] Unexpected downtime of cloud computing servers is an inevita...

Problems solved by technology

This method uses AHP as the core idea of ​​decision-making and scheduling, but AHP needs to be constrained by different parameters for nodes with different scenarios and functions, so the weight values ​​obtained are different, and the evaluation criteria are difficult to unify. Automatic migration of virtual machines, but its efficiency is not high
