The Internet has reached a crossroads in its evolution from a source of information to a critical infrastructure, underpinning economies and everyday life. The demand for more multimedia content, interconnected devices, greater connectivity, richer user experiences and services available at any time and from anywhere is increasing the pressure on existing networks and platforms. In this ubiquitous Internet, the number and scope of services available globally are predicted to grow exponentially leading to the ‘Internet of Services’. However, in order for these services to be used and re-used in the construction and evolution of service-based systems, significant research effort is required into the broader aspects of services and particularly into the multidisciplinary problems that cut across diverse scientific disciplines. The S-Cube Network of Excellence is one of more than 50 projects within the European Union's FP7 - ICT Programme for Research and Development researching various aspects of the Internet of Services. Within this cohort, S-Cube focuses on fundamental principles, techniques and methods for the service-based systems of the future, combining knowledge from experts in the areas of grid computing, service-oriented computing, business process management, software engineering and human-computer interaction. This book presents the foundations, vision, first results and future work in the area of software services as addressed by S-Cube. The book starts with a presentation of the S-Cube research framework, developed to assist in unifying research communities and agendas across Europe, and provides an introduction to the vision of S-Cube, where the anticipated growth in services and service-based systems will have a profound effect on business and society. The remainder of the book follows the building blocks of the research framework and addresses technologies required for realizing future service-based systems and service engineering principles, techniques and methods that use those technologies to ensure robust, manageable and adaptable systems.
