Implement of a Light-Weight Integrated Virtualized Environment Manager for Private Cloud Computing

Cloud computing is of particularly population these days, it is changing the way of delivering and consuming IT resources of kinds. Private cloud computing is more appealing and acceptable than public cloud computing at this stage since there is no security issue which is intensively concerned by all serious users. But on the one hand, currently widely used open source virtualized environment managers can not meet the requirement of private cloud especially small scale private cloud due to their overstaffed functionality and complexity, on the other hand, customized commercial managers always involve a significant mount of fees and it is hard to be integrated by other applications running in the cloud. Based on the deep investigation on virtualization technique especially on Xen, the design and implement of a light-weighted integrated virtualized environment manager (LWIV Manager) is presented in this paper. LWIV Manager provides an easy use and integration way to allocate the computing resources of CPU, memory and network in the cloud. Moreover, a plug-in which gathers public computing resources to scale the capacity of local private cloud in the case of request burst is integrated in our LWIV Manager as well.
