Welcome to the 8th International Conference on Service Oriented Computing (ICSOC 2010), held in San Francisco, December 2010. These proceedings rep- sent high-quality research and industry papers, tutorials, demos, and posters that showcase new developments in service oriented computing and related ?elds. Since the ?rst meeting in beautiful Trento in 2003, ICSOC has become the premier conference in the rapidly evolving areas of service research. While ke- ing its roots in scienti?c excellence and technical depth of service technology, ICSOC 2010 aimed to combine technical aspects of service computing with - plication and business-oriented aspects of service design, following the recent emergence of service science as an interdisciplinary foundation for understa- ing and integrating service systems. Located in the center of technology inno- tion,the SanFranciscoBayArea,this year'sICSOC,throughits LocalAdvisory Board, reached out to local industry and academia for keynotes and panels on current topics and to connect technical invention with commercial innovation. The Program Committee faced some tough decisions this year. We received 238submissions,signallingagrowingcommunityofresearchersandpractitioners working in this multidisciplinary ?eld. All papers were considered carefully by the Program Committee in originality, novelty, rigor, and relevance. In the end, 33 full research papers and three full industry papers were selected, resulting in an acceptance rate of 15%. An additional 18 submissions were accepted as short papers. There were also three PhD symposium posters and four regular postersaccepted.Paperandposterpresentationswerecomplementedbytutorial and demo programs. All represented the state of the art in service oriented computing.
