Virtualization and cloud computing

Abstract

Cloud Computing is the fundamental change happening in the field of Information Technology. It is a representation of a movement towards the intensive, large scale specialization. Virtualization is the key component of cloud computing. With the use of virtualization, cloud computing brings about not only convenience and efficiency benefits, but also great challenges in the field of data security and privacy protection. For example, it maybe bind different tenants' virtual resources to the same physical resource, then the user data will be accessed by other users. To solve this problem, the paper analyses and discusses several ways to improve the safety of cloud computing. © 2012 Springer-Verlag GmbH.
