Design Of Cloud Computing Platform Based On Server Virtualization

Cloud computing is a service delivery and usage pattern, which can provide the IT resources as a service for users on-demand use. As a new business model, cloud computing is very likely to bring a new change for the IT industry, so how to build a flexible, efficient, robust cloud computing platform has become a major research focus for domestic and foreign IT companies.The paper designed a cloud computing platform based on server virtualization technology to offer infrastructure as a service(IaaS). The system is established on a computer cluster which includes a large number of servers. It achieved the on-demand division and dynamic allocation of resources though the virtualization technology, and also achieved high availability and load balancing by using the rapid deployment and real-time migration capability of the virtual machines.Supporting several virtualization technologies is a major feature of the system. The system can management the virtual machine of Citrix Xen, VMware, Redhat KVM and Redhat Xen though XML-RPC, SOAP or libvirt library. The management operations are tested at the end of the paper. The test results show that the system can provide good supports for above four type virtual machines.
