Efficient Virtual Machine Deployment in Large Scale Resource Environment

Combining virtual machine technology, virtual computing is able to effectively aggregate the widely distributed resources to provide users services. We view the federation of multiple data centers and voluntary resources on the Internet as a very large scale resource pool. Based on the tree structure of the pool, this paper proposes a virtual machine deployment algorithm, called iVDA, considers users’ requests and the capabilities of the physical resources as well as the dynamic load, implements an adaptive mechanism to scheduling servers to host virtual machines forming virtual execution environments for various applications, and supports on-demand computing.
