Information Systems: Information Systems are more than just a database or a computer program. It is a set of processes, tools and standards that allows us to manage information stratigically,work efficiently, support business processes, and to communicate effectively and the most important is to make better decisions.Evolution and Trends of Information Systems and Infrastructure.The field of information systems (IS) has evolved along with the development of information technology and applications over the past twenty years. It is important to understand how the research issues have evolved in the past and what are the driving force underlying the evolution.  We found an increase in human-related research and a decline in systems-related research. Two major trends are identified: one driven by system design issues (1980-1993) and the other driven by human factors and system applications (1993-2001). Two underlying forces behind the research have been new technology development and organizational needs. The evolutin is from EDP’s to MIS, and PC and  DSS , then EIS to Internet, Then Artificial Intelligence, to KMS, then to cloud computing.Major Trends Forces behind the Trends:* System design issues ,IS performance Evaluation, New Software Technologies, Telecommuniucation Systems*Consumerization and the tablet: Widespread use of tablets, such as the iPad, and other mobile devices in business isn’t seen as replacing the traditional computer desktop entirely *Infinite data center: The movement toward smaller size but greater density in data centers, combined with a trend to analyze performance per kilowatt, is leading to energy management as a newer type of discipline, even for “moderately energy-intensive organizations,  *Mobility and the personal cloud: “The whole concept of PCs is going away,” said Cappuccio, noting that employees, who today often carry multiple mobile devices, may want to use some of them under BYOD conditions in the enterprise. Not only should enterprises immediately evaluate BYOD for their own situations, and consider a “self-service culture for users,” but acknowledge that mobility is going to have a cascading effect on how internal physical infrastructure is built — or not built at all — in the future. IT complexity: The complexity of technical changes, combined with trend such as virtualization, mobility and cloud computing, are only increasing the complexity of IT management, he said. In this situation, what’s needed is a “generalist at a high level who can figure out what the cascade effects are,” and that kind of person in the center of things will play an increasingly important role is helping IT matters run well.Conclusion: The Evolution  in Information systems has transformed how we live and how we do business today. The organisations and society have benefited a lot from the evolution since  50 years. techology changes quickly from time to time and we as the user of the technology have to groom and  keep us closely with the fast pace of technical changes to stay competitive in the dynamic marketplace. References: above articles are shows us the how the informations systems has evolved from the 50 years and how the infrastructure is being developed in a way that would leads to the modern and the future trends.
