Embodiment 1

[0102] For the simulation of the first algorithm, the same physical machine and virtual machine are used, all including materials and performance are the same. Three groups of virtual machines are used, the numbers are 60, 70 and 80 respectively, and a group of physical machines is used, the number is 14. The basic inputs are: virtual machine resource vector group, physical machine resource vector group and traffic matrix between virtual machines. Energy consumption is calculated using random, FFD, T-opt and VM-P algorithms, respectively. The result is as figure 2 shown;

[0103] Depend on figure 2 It can be seen that:

[0104] For A1, the abscissa represents the number of virtual machines, and the ordinate represents energy consumption, and the unit is w. It shows the difference in energy consumption of the four algorithms. The mapping between VM and PM is different, resulting in different energy consumption. Tool formula (10) can calculate energy consumption. Each P...

Abstract

The invention discloses a virtual machine scheduling method for safely improving resource efficiency in Iaas cloud. Optimization is conducted from two aspects, and one aspect is the aspect of static deployment of a virtual machine, wherein the physical capacity and the bandwidth capacity are met to minimize the resource consumption of a data center; the other aspect is the aspect of dynamic migration of the virtual machine. In the aspect of the static deployment of the virtual machine, the physical capacity and the bandwidth capacity are met to minimize the resource consumption of the data center; through the resource consumption change of the virtual machine in the dynamic change process, running of the virtual machine is guaranteed to the greatest extent; in the aspect of the dynamic migration of the virtual machine, the migration cost is minimized to obtain the maximum link utilization rate and reduce the resource consumption. According to the virtual machine scheduling method for safely improving the resource efficiency in the Iaas cloud, the minimum migration cost is adopted to obtain the maximum link utilization rate and reduce the resource consumption.

Description

technical field [0001] The invention belongs to the field of computer cloud computing, in particular to a method for scheduling a virtual machine based on safely improving resource efficiency in an IaaS cloud. Background technique [0002] Cloud computing provides users with on-demand services, which are flexible, reliable, and low-cost. The infrastructure is the cloud computing center. As the scale of cloud computing becomes larger and larger, resource consumption continues to grow, resulting in increased operating costs. According to Microsoft's report, the physical resources of the data center (such as CPU, memory, storage) account for 45% of the total cost, and the energy consumption accounts for 15%. In the past five years, the energy consumption of the data center has nearly doubled. Therefore, how to reduce energy consumption and improve resource efficiency has become an important issue. [0003] Due to the low utilization rate of the server, a huge power waste is c...
