In recent years, cloud service has become a hot topic. Fanned by media manipulation, cloud service issues not only receive proper focus, but also attract lots of enterprise investments into this field therefore cloud service has become one of the major policies for IT development in many countries. Nonetheless, if one wants to take an in-depth approach in understanding the current status that enterprise adopts the cloud service, it won’t be hard to realize that presently only few enterprises really have selected the cloud service. Moreover the majority of enterprises exhibit no strong willingness in adopting this service in the nearest future. Thus this renders the cloud service market in a wait-and-see mode.
If one wants to explore the reason why, besides the fact that enterprise cannot reassuringly places its sensitive information and have it safely stored in the public owned cloud service, but also the public owned information safety mechanism has not secured the trust from the enterprises in a convincing way. As for the existing stage for the enterprise using cloud service, the privately owned ones remain high on its priority list. Within the privately owned operation architecture for the cloud service, and through the induction of virtual algorithm technology, these can render the integration of servers at the enterprise end and the optimization for the infrastructure as well. In addition, this can lower the operation costs, enhance the operation flexibility as well as the response speed, raise the level of usability for application programs, improve the operation durability, augment the desktop management capability and security,
Hence this thesis takes the approach of IT security while exploring the possibly and ensuing security concerns stemmed from cloud services adopted by the enterprises. Therefore this study adopts the researches on the reliable and privately owned cloud service platforms as the main theme and proceeds to simulate and test so as to come up with the most optimum solutions.
