Cloud Computing - Issues, Research and Implementations

Cloud computing - a relatively recent term, builds on decades of research in virtualization, distributed computing, utility computing, and more recently networking, web and software services. It implies a service oriented architecture, reduced information technology overhead for the end-user, great flexibility, reduced total cost of ownership, on-demand services and many other things. This paper discusses the concept of "Cloud" computing, some of the issues it tries to address, related research topics, and a "Cloud" implementation available today.
