Virtualization vs. cloud computing

• “… virtualization differs from cloud computing because virtualization is software that manipulates hardware, while cloud computing refers to a service that results from that manipulation.”• “The difference is that a true cloud provides self-service capability,

elasticity, automated management, scalability and pay-as you go service that is not inherent in virtualization”• http://www.businessnewsdaily.com/5791-virtualization-vs-cloud-
