Research And Design Of University Desktop System Based On Cloud Platform

With the increasing popularity of information technology,cloud based systems have become more and more attention.In cloud service environment,it can effectively improve the efficiency of resource use,get better results,research and development of cloud platform cloud platform system has important research significance and practical value.The main work of this paper is as follows:(1)demand analysis based on desktop cloud platform system.According to the requirements of software engineering,the system users are analyzed,the functional requirements and non functional requirements are analyzed,and the requirements of users are described by using UML tools.(2)the design of the desktop cloud platform system.The first is the overall design of the system,on the front of the demand for detailed decomposition,follow the cloud computing standards,adopt multi-layer architecture,complete the design of the overall framework of the system architecture,system can be divided into three levels namely the client layer,middle layer and data layer;then design business functions,divided into seven function the module and the detai led design of the function modules of each of the design class diagram,timing diagram design,the system database design.(3)implementation and testing based on desktop cloud platform system.When designing first of all is to build a suitable development environment,and according to the requirement analysis and system design of the contents of the corresponding code and interface for each module of code writing and debugging.The main functions of the system include the design of the virtual host dynamic scheduling,improved dynamic migration of virtual machines in the cluster algorithm,describes the implementation process and pseudo code,improve resource utilization,realize resource allocation in accordance with the requirements.From the two aspects of system function and performance testing system to meet the user requirements,through the integration of hardware resources,can use the existing hardware resource utilization rate,greatly improving the utilization of existing resources.Desktop cloud platform system realized in this thesis can be converted into a pool of physical resources of the server computing unit can be dynamically allocated the,starting from the specific planning requirements,in the resource pool is divided into the specific business needs of the service for computing unit,no longer limited to the physical boundaries,so as to improve the utilization rate of resources,simplify system management.
