Cloud computing: Models, services, utility, advantages, security issues, and prototype

Abstract

Cloud computing has tremendously evolved from recent advancement in virtualization technology, resulting in utilization, enhancement, and transformation to more computational requirement model such as on demand and pay-per-use services. The advent of internet early 1990 to present day has helped to facilitate the era of ubiquitous computing. This has lead to transition from the concept of parallel, distributed, grid, and presently cloud computing. Cloud computing have ushered an environment where different computing resources such as application, networks, and storage can be shared via internet infrastructure by users anytime, anywhere without constraint to hardware or resource requirement. This paper explores cloud computing deployment models, services, utility classes, advantages, security issues, and prototype.
