Research And Design Of A Cloud Computing’s Security Based On Virtual Database Center

The Cloud Computing has been a hot issue in the field of technology. It reflects the thought that the network is the computer. It brings a wide-ranging and deep-going transformation because of the innovative calculation mode and structure of business. As the technology of cloud computing further in depth and the expansion of its markets sized, it has presented an unprecedented challenges for national information security, enterprise safety and personal privacy. From time to time burst of cloud computing security issues have led many companies falter.The core technology of the cloud computing security is the trust mode. It has an effect on the system stability and the security. It can be strategic importance to the sustainable development of the cloud computing service.It can access and control data safely through research on Virtual Database Center (VDC). The VDC integrates the International Database Center resource with the virtualization technology, and it achieves computing, storage, network resources according to its need. The virtual resources have been brought by central management. VDC takes charge of network configuration, distribution, management and monitoring. In this paper, The design of Cloud security framework is discussed in detail, including the safety design of Cloud and its Client. The Role-Based Promission Control model is designed for the dynamics of the Cloud Computing system. According to the networking cloud requirement, the security architecture of International Database Center is proposed combined with the VDC project practice. The long term evolution of the Cloud Security was made in light of the information security protection grade four basic principles.The VDC is using in Shanghai, Beijing, Qingdao and Jinan. Five Cloud computers is working in the3G telephone area, as well as three computers is used in the fiscal test system. It can better accomplish desired goals.
