Evaluation and Comparison of Security Issues on Cloud Computing Environment

Cloud computing basically comes to focus on IT, a way to increase capacity or add potentiality on the fly without investing in new infrastructure, training new personnel, or licensing new software. It encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends its existing capabilities. It is often provided "as a service" over the Internet, typically in the form of infrastructure as a service (IaaS), platform as a service (PaaS), or software as a service (SaaS). Microsoft Azure and Google App Engine are the examples of platform as a service. The fast growth in field of “cloud computing” also increases rigorous security concerns.This paper describes about the performance of different security algorithm on a cloud network and also on a single processor for different input sizes and advanced Encryption Standard security algorithm implemented for ensuring security framework.
