Improving cloud security through virtualization

Abstract

Cloud Computing is accessing Services through Internet based on pay per usage model. Software as a Service (SaaS), Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) are available in Cloud. Cloud based products will eliminate the need to install and manage client rich applications. Cloud Service providers are helping companies to reduce the high cost infrastructure installation and maintenance cost. The customer is charged only for the resources consumed like utility based computing. Virtualization is a technique to implement cloud computing resources such as platform, application, storage, and network. The beauty of virtualization solutions is that you can run multiple virtual machines (VM) simultaneously on a single machine. This paper provides details about cloud computing issues, how virtualization techniques can be used to overcome those issues. © 2011 Springer-Verlag Berlin Heidelberg.
