Embodiment Construction

[0064] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0065] Such as figure 1 As shown, a hybrid cloud scheduling model includes a user interface, a task request manager and a scheduling manager; the user interface is used to send the task request submitted by the user to the task request manager, and the task request manager is used to transmit the task request information To the scheduling manager, the scheduling manager combines the resource information of the public cloud and the private cloud stored in the scheduling manager according to the task requirements, and uses the hybrid cloud scheduling method to schedule the task to the public cloud or the private cloud. The result is returned to the user.

[0066] Task request information include...

Abstract

The invention discloses a model and a method for scheduling for a mixed cloud based on deadline and cost constraints, which aims at solving the problems of low utilization rate of a private cloud and high cost of a public cloud in the scheduling process of the mixed cloud. The method comprises the following steps of proposing two scheduling strategies, namely the deadline priority and cost priority strategies, according to the property and cost targets; establishing a task and resource model of the mixed cloud, adaptively selecting the proper scheduling resource according to the task submitted by a user, firstly scheduling the task with higher requirement on the deadline to the public cloud, and also firstly scheduling the task with higher requirement on the cost to the private cloud, so as to enable the two strategies to meet the deadline and cost constraints. The method has the advantages that the two scheduling strategies can be well performed at the aspects of scheduling completing time, cost, deadline exceeding rate and private cloud utilization rate; especially when the task workload is high, the two scheduling strategies have better self-adaptive property and advantages.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a scheduling model and method based on deadline and cost constraints in a hybrid cloud. Background technique [0002] At present, with the expansion of enterprise applications and the doubling of data volume, especially during peak hours, the existing clusters of enterprises cannot meet all the needs, so a large increase in investment in hardware facilities is required. However, except during peak hours, the utilization rate of most equipment is not high, resulting in a waste of a large number of hardware equipment and an increase in operating costs. Therefore, in order to reduce hardware investment and maintenance costs, more and more enterprises choose hybrid cloud as the enterprise application deployment platform. In addition to the enterprise's own local private cloud in the hybrid cloud, when the computing power of the private cloud cannot meet the requirements, it can direct...
