Abstract

The invention discloses a time-perceptible request scheduling method in a hybrid cloud environment. The method comprehensively considers the changes of the unit time execution costs of virtual machines in a public cloud and a private cloud, the energy price of the private cloud and other factors in the request delay time requirements. For the request of delay-tolerant applications, the method comprises the following steps: modelling the private cloud and the public cloud as a discrete time system that consists of equal time intervals, and on this basis, establishing a non-linear constrained optimization model of the request scheduling for maximizing the private cloud profits in the hybrid cloud environment, transforming the model into an unconstrained optimization model by adopting a penalty function method, and then solving the unconstrained optimization model by adopting a hybrid metaheuristic optimization algorithm based on simulated annealing and particle swarm optimization algorithms to achieve the time-perceptible request scheduling in the hybrid cloud environment. According to the time-perceptible request scheduling method disclosed by the invention, all arrival requests can be intelligently scheduled to the public cloud and the private cloud for execution, the profits of private cloud providers can be maximized, and the delay time requirements of all the requests can be ensured.

Description

technical field [0001] The invention relates to the technical field of cloud computing resource scheduling. More specifically, it relates to a time-aware request scheduling method in a hybrid cloud environment. Background technique [0002] Cloud computing services can provide on-demand resources to a large number of users through the network. The resources in the cloud data center usually dynamically provide services to users in a pay-as-you-go manner. Additionally, the economies of scale offered by cloud computing have attracted more and more companies to deploy their applications in cloud data centers. As a typical cloud computing model, infrastructure cloud service providers (such as Rackspace and Amazon EC2) provide services to users on a pay-as-you-go basis. [0003] According to the definition of the National Institute of Standards and Technology (NIST), a private cloud usually refers to a cloud whose infrastructure resources are exclusively occupied by a single or...
