Security Issues and Solutions in Cloud & Grid Computing

Abstract- Cloud computing is clearly one of today’s most enticing technology areas due, at least in part, to its cost-efficiency and flexibility. Cloud computing is a growing area of concern in the IT security community because cloud architectures are literally popping up all over. However, despite the surge in activity and interest, there are significant, persistent concerns about cloud computing that are impeding momentum and will eventually compromise the vision of cloud computing as a new IT procurement model. In this paper, we characterize the problems and their impact on adoption. In addition, and equally importantly, we describe how the combination of existing research thrusts has the potential to alleviate many of the concerns impeding adoption. In particular, we argue that with continued research advances in trusted computing and computation-supporting encryption, life in the cloud can be advantageous from a business intelligence standpoint over the isolated alternative that is more common today. Public clouds are available from Google.com, Amazon.com, Microsoft, Oracle/Sun, Canonical/Eucalyptus and many other vendors. Private cloud technologies, where the cloud software is loaded on local or in-house server hardware, are available from VMware, Eucalyptus, Citrix, Microsoft, and there are thousands of vendors offering “cloud solutionsâ € !
