Server virtualization enables a physical computer to support multiple applications logically by decoupling the application from the hardware layer, thereby reducing operational costs and competitive in delivering IT services to their enterprise organizations. IT organizations continually examine the efficiency of their internal IT systems and their IT organizational processes. Researchers suggest that server virtualization technology is a disruptive innovation, but IT professionals must manage the decision process regarding server virtualization to ensure success because a poor employment of server virtualization can jeopardize the effectiveness of service delivery to its enterprise organizations. Today, IT professionals have only to read the latest news or perform pilot analysis to identify the employment of the server virtualization technology. This qualitative study explores the factors that influence the decision-making process regarding the choice to employ server virtualization technologies within organizations. This study also explores the perceptions of IT virtualization practitioners in order to identify valuable heuristics that will assist IT professionals when making decisions to employ server virtualization technologies. It is certain that no matter what the core business, corporate executives and strategic planners are increasingly turning their attention to opportunities for achieving competitive advantage through information technology. They are relying on existing transaction processing and decision support systems as foundations for their competitive advantage. The server is the key technological components that host these systems; without the server these processes could not function. As a result, the decision process should be made cautiously and intelligently to avoid the negative impacts that server virtualization technologies can have on an organization. The conclusions indicate that IT professionals perceive server virtualization technology as a competitive weapon within their organizational tool kit where its employment would lend itself better to a framework that enable decision making during each phase of the server virtualization lifecycle.
