Emerging trends in IT: from clusters to cloud computing

Abstract:

Within our worldwide society of knowledge, Mankind has expressed its desire to fulfill one’s need using different resource. The last decade information technology development gave rise to new IT trends enabled by technological innovation peaks at the beginning of the twenty first century. What is the meaning of computing as a resource? Scientists lead us to rethink our organization from a computer-resource centric view. Research and development as well as businesses lead and perform their daily activities using computing as a utility. Gain productivity, minimize expenditure, and optimize organizational infrastructure are current public and private issues to which IT can bring solutions. Indeed, in our competitive global economy, governments and companies need to take advantage of these emerging trends to build a significant competitive advantage. The concepts underlying emerging trends in IT are recurrent, connected and often overlap. That paper will bring concise definitions of the most important, explain their relation, and provide illustrative examples to offer a clear mental mapping for the today’s prominent virtual environment.
