Design And Implementation Of Virtual Resource Access Management And Task Scheduling In Private Cloud Platform

A key problem of virtual operation environment, is the choice of resources, another key problem to the environment of the virtual operation is a task scheduling. It is an effective and reliable in order to put the task scheduling and resource scheduling selecting resource nodes. Everywhere in virtual operation environment, the resources, its form condition is different, so the traditional way of management is not applicable, therefore need a dedicated resource for a virtual computing environment research, mainly for and resources selection, and how to run on task scheduling efficiently in its use.Emergency center to establish public open Internet infrastructure services, provides a virtual machine environment. His desire to provide reliable and efficient service. But because of its characteristics, on the one hand, resource nodes characteristic difference is big, on the one hand to run the application demand of varied also. Creating a how to select more reliable resources effectively, how to carry on the task scheduling in the demand, the two problems gradually become the factors that affect the service.In this paper, combined with the actual situation of the Internet cloud platform emergency center, in which first introduced the credit system, and then to design the resource selection strategy, and further design to achieve the task scheduling subsystem. In this paper, the innovations include:(1) put forward a kind of credit evaluation system based on the application of resource nodes, and proposes the corresponding resource access strategy choice.(2) the task scheduling based on cloud platform middleware system was put forward, and its module architecture design, system development, and ultimately would achieve. The scheduling system, as a connection bridge between users and cloud platform resource nodes, for the user to meet the target assignment, and then completes its custom applications run on the platform, and finally get the result that the whole process, the scheduling management.(3) combined with the above scheduling middleware system design idea, the final at the national center for Internet emergency, combined with the corresponding open development interface and development service, develop the task scheduling system is achieved, and completed the scheduling process of concrete application, implement the task of distributed, and smoothly to achieve significant measurements, the researchers for the center of the further research work, provides the data support.In terms of implementation results, the implementation process, relevant tests to verify, can be concluded from-the actual results, through the application in the system in this paper, the resource selection strategy, effectively improve the success rate of task execution, the improvement of the system resource utilization, at the same time, through the use of scheduling policy effectively reduced, submit to the cloud platform submit time consuming in the process of task. Finally, combining to retrieve the data and the results of the graphical display, can see very good completed the scheduling system, in view of resource nodes in the network speed this specific application, run on a cloud platform task scheduling management process.
