Cloud Computing - an IT paradigm changer

Abstract

Cloud Computing is an emerging computing paradigm envisioned to change all IT landscape facets including technology, business, services and human resources. It is a consumer/delivery model that offers IT capabilities as services, billed based on usage. Many such cloud services can be envisioned, but the leading ones are IaaS (Infrastructure-as-a-Service), PaaS (Platform-as-a-Service), and SaaS (Software-as-a-Service).
