The evolution towards a service-based economy represents today more than 70% of the GDP in developed countries. This evolution is expected to continue and to influence our lifestyle in the coming decades but the full potential of the service-based economy can only be grasped if it builds on new technologies for the design, development and operation of new services and service platforms.

Service-oriented computing is an emerging cross-disciplinary paradigm for distributed computing, which is changing the way software applications are designed, delivered and consumed. At the heart of service-oriented computing are services that provide autonomous, platform-independent, computational elements that can be described, published, discovered, orchestrated and programmed using standard protocols to build networks of collaborating applications distributed within and across organizational boundaries.
