Abstract

Recently, advances in networks, processors and storages for computer architectures have affected computer organization systems leading to a metamorphose of traditional systems. The increasing demands for well adapted computer infrastructure and different services along with advances in IT industry have motivated researchers to extend the possibilities of virtuality and virtual mechanism in a wide area of computing problems in order to better respond to daily work and business opportunities to produce high quality services and products. Therefore, we call all these processes Virtual Computing (VC). In this paper, a thorough survey of VC is presented including definitions, characteristics, challenges, issues, and novel potentials to enhance organization methods in the field of computer architecture. Exemplarily, we describe two application fields, energy efficiency and cloud security, to demonstrate new ways of optimization of overall system's architectures using virtualization.
