Cloud Computing and Related Security Issues

Cloud computing as a technology is difficult to define because it is evolving without a clear start point and no clear prediction of its future course. Even though this is the case, one can say that it is a continuous evolution of a computer network technology going beyond the client–server technology. It is a technology extending the realms of a computer network, creating an environment that offers scalability, better utilization of hardware, on-demand applications and storage, and lower costs over the long run through the creation of virtual servers cloned from existing instances each offering near instantaneous increase in performance, allowing companies to react quickly and dynamically to emerging demands. The “cloud” or “cloud solution,” as the technology is commonly referred to, can either be hosted on-site by the company or off-site such as Microsoft’s SkyDrive and Samsung’s S-Cloud.
