Embodiment

[0075] 200 isomorphic physical servers are used to simulate the physical host group of the cloud computing center. The CPU processing capacity of the physical server is 2660*2MIPS, the memory capacity is 4096MB, and the network bandwidth is 1Gbit / s. The types of virtual machines used in the simulation experiment and related parameter settings are shown in Table 1 and Table 2, respectively. There are four types of virtual machines. After normalization, they are: S1=(0.1,0.2,0.1), S2=(0.2,0.4,0.1), S3=(0.4,0.4,0.1), S4=(0.5,0.2, 0.1). The simulation experiment uses 100 virtual machines, and the type of each virtual machine is randomly selected from four types of virtual machines. The load data of each virtual machine comes from the CoMon project, and the load data duration is 24 hours. The physical hardware configuration for running the simulation platform is CPU Intel Core i5-3470 3.2GHz, 4G RAM, and the operating system is Windows 7.

Abstract

The invention discloses a three-dimensional virtual resource scheduling method of cloud computing energy consumption key. The method comprises the following steps: step 1, performing virtual resource allocation; step 2, performing overload host detection, and detecting each physical host of a cloud data center by adopting a multi-dimensional host overload detection method to judge whether the physical host is overload; step 3, performing migration virtual machine selection, and selecting a to-be-migrated virtual machine by adopting a virtual machine selection method; step 4, selecting a target host, and selecting a new physical host mode for each migrated virtual machine by adopting a target node selection method; and step 5, performing virtual resource optimization to further reduce the energy consumption. According to the three-dimensional virtual resource scheduling method disclosed by the invention, how to effectively reduce the energy consumption of the data center is fully considered from the three dimensions of CPU, memory and network bandwidth, so that the virtual resources of the cloud computing data center are efficiently scheduled and managed, the resource utilization rate is improved, and the energy consumption of the data center is effectively reduced.
