The Research On The Resources Scheduling Of Campus Service Platform Based On Cloud Architecture

This essay has taken advantage of the cloud computing technology to construct the vocational school information service platform so that it can further explore the potential value of the campus hardware and avoid the huge waste led by the repeated construction of a large number of hardware resources because of the educational informationization.Unifying various kinds of application systems into the virtualized resource pool of the cloud computation to obtain the storage and management of data can guarantee a lower level of costs of and maintenance of software and hardware,which will be able to build up a more solid base for the unified management and adjustment of all systems and increase the convenience of users' visits and the sharing level of resources.This research has analyzed the currently popular cloud computing technology and the development trends of the educational information processing and focused on the following three aspects:1.Based on the analysis,it has suggested the application of cloud computation into the construction of the campus service platform and it has designed an intelligent campus service platform based on the cloud computing framework.Through the Hadoop cloud computing framework,the cloud computing cluster environment has been created.It has also paid lots of attention to the supervision and research of the resource scheduling of virtual machines of the service platform.2.It has put forward to the dynamic scheduling algorithm based on threshold to achieve the dynamic transfer of virtual machines in the cluster and make a comparison between it and the static scheduling algorithm with mutual independence with virtual machines.The result has proved the advantage of dynamic scheduling algorithm based on threshold in its decreasing the operation time of tasks.In order to meet the diversified and prioritized needs of the platform users in the cloud environment,the research has improved the tasks' scheduling of the first come first service offered by the service platform constructed.3.This essay has integrated the weighted round robin with priority into the tasks' scheduling process,which has improved the functions of the system to a certain degree.In addition,it has taken advantage of the campus network infrastructure environment to make a comparison experiment and the result has effectively proved the advantage of the weighted round robin with priority.
