Design Research Of The Cloud Computing Platform Based On Virtualization Technology

Cloud computing is a new model of Internet-based IT services. Through the network thescalable and virtualized IT resources can be provided for users on demand in the form of servicesdynamically. Currently the cloud computing is the revolution in the IT industry followingmainframe computers, personal computers and Internet. Therefore, how to build a more efficient,stable and flexible cloud computing platform has become a hot research topic.This thesis takes the OpenStack open source cloud computing platform of Intel Corporation as auniversal front end of IaaS resources. Through server virtualization technology, this thesis proposesa security and efficient cloud computing platform framework. The platform is built on top of thecomputer cluster combined by servers to provide the function of the infrastructure as a service.In this thesis, a real-time detection strategy of the system physical devices is given for solvingthe problem of load balancing with the dynamic migration technology in virtualization environment.This method is capable for the rapid implementation of virtual machine migration or its fastrecovery, and ensures the availability and continuity of the services provided by the system.Meanwhile this thesis designs a new energy management programs and realizes a dynamicmanagement of the energy consumption in the system to support the entire system load balancingmechanism. The experimental results show, the design scheme can provide the efficientinfrastructure services, and can save nearly30%energy without affecting the performance. It caneffectively improve the resource utilization and reduce the energy consumption in cloud computingplatforms.
