We are pleased to welcome you to the eleventh edition of the Middleware c- ference. The program this year is a sign of the robustness, activity, and cont- ued growth of the Middleware community. As computing technology around us has evolved rapidly over the past decade, our notions of middleware have also adapted so that we stay focused on the most challenging and relevant problems for the present and future. As a result, this year’s program features papers that belong to both tra- tional areas as well as new directions. Cloud computing, social middleware, and transactional memory are some of the vanguard areas that you will ?nd in this year’s selection of papers. In addition, topics that have always been central to the community are also prominent this year, including publish-subscribe, mul- cast,reliability, legacy,location-awareness,trust, and security.The community’s wise evolutionre?ects the dynamic role that middleware continues to play in the development of current software systems. The program underscores the competitive selection process applied by us and the technical programcommittee: out of 116 papers submitted this year,we accepted 18 for regular publication. In addition Middleware 2010 also includes a new category of “Big Ideas Papers,” which are bold white papers with the potentialtodrivelonger-terminnovationinthe?eld.Weselectedone“bigideas” paper this year. Our industrial track once againbrings forth papers that explore middleware foundations in the context of industrial practice. Finally, multiple workshops and a doctoral symposium round o? Middleware this year, making it an attractive conference for students, faculty, researchers, and practitioners.
