Embodiment Construction

[0059] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0060] A hybrid cloud service process scheduling problem model considering virtual machine deployment and periodic pricing model

[0061] Its modeling objective is to minimize the total cost. Considering that under the price discount model, the billing duration of a virtual machine may cover multiple billing intervals (each interval has a different billing price), so it is necessary to calculate how many billing intervals the billing duration covers, and then Get the cost of each virtual machine, as shown in formulas (1)-(2):

[0062]

Abstract

The invention discloses a hybrid cloud service process scheduling method considering virtual machine deployment and a periodic pricing mode. The invention discloses a hybrid cloud service process scheduling method considering virtual machine deployment and a periodic pricing mode. The method comprises the steps of obtaining a task set TS; a hybrid cloud CPS; a physical machine set PMS; a periodiccharging mode TCM; wherein the maximum number of iterations is Maxiter; wherein the size of the group is Gpop; the maximum generation number E of sparks; a maximum explosion amplitude R; an initial temperature T; a cooling rate cr; in an initial stage, a group of initial firework populations are generated firstly; for each firework, the fireworks are randomly coded into a real number list, and thereal number list is expressed as a priority list of tasks; decoding each firework into a complete scheduling solution, and calculating a target value of the solution; in the iteration stage, fireworks are continuously updated, and once the stop condition is met, the optimal solution is output. The beneficial effect of the invention is that the formalized model of the invention considers the periodic charging mode widely used in cloud computing.

Description

technical field [0001] The invention relates to the field of cloud services, in particular to a hybrid cloud service process scheduling method considering virtual machine deployment and periodic pricing models. Background technique [0002] Cloud computing is a new service model based on virtualization technology and on-demand usage to realize service invocation. Specifically, it is divided into: public cloud, private cloud and hybrid cloud model. For many small and medium-sized enterprises, using a single public cloud platform can reduce infrastructure construction costs, but it is difficult to guarantee data security. On the contrary, if an enterprise only uses a private cloud, it is often difficult to bear a large amount of infrastructure construction and daily maintenance costs. The hybrid cloud model is not only conducive to making full use of the existing resources of the enterprise and ensuring the security of confidential data, but also has the advantages of elasti...
