The Design Of Private Cloud Computing Platform Based On Virtualization Technology

The landmark technology in information science field usually disappears every couple years.The first revolution in IT technology focus on the PC, the second IT technology revolution isbased on the Internet,and the third one regards the cloud computing as the core. Cloudcomputing is a mode which makes it possible to access to the allocating resource(such asnetworks, servers, storage, applications, and services) according to the demand. For example, thecloud computing technology can greatly improve the utilization rate of equipment in datacenter,avoid the economic losses of the idle equipment, and reduce the personnel andmanagement costs.This is greatly attractive to the business.Therefore,how to build a flexible,efficient and robust private cloud computing platform has become one of the focus of the majordomestic and international IT companies.Paper is designed to build a green private cloud computing plaetformdwhich is effective toreduce operation and maintenance costs, simplify management, improve system highavailability,make dynamic adjustment to resources and achieve load balancing between systems,.The platform is built on a computer cluster composed by a large number of servers, and provideexternal infrastructure as a service (IaaS), while the demand for resources distribution andsystem partitioning and dynamic load balancing, high availability, live migration is achieved byvirtualization technology.Considering the user may not be a single network model, and the server’s operating systemmay also exist diverUsity, mnoreoRver, alethouggh thieres aret ae variety of virtualization productscurrently on the market, As a mainstream product,the Citrix Xen, VMware virtualizationtechnology are ideal buy products in terms of performance or maturity. Thus, the system alsosupports the virtualization technologies such as Citrix Xen, VMwarre and so on.
