ISAS 2008, the 5^th in the series of ISAS Events (International Service Availability Symposium), was hosted by Prof. Takashi Nanya at the Research Center for Advanced Science and Technology (RCAST), University of Tokyo in May 2008. Close to 80 participants from industry and academia showed the importance of the conference, which celebrated its 5th anniversary.

The program committee co-chairs, Andras Pataricza, Budapest University, and Fumihiro Maruyama, Chairman Fujitsu Laboratories Europe, had put a very diversified program together, giving room for presenting new research results and industry reports. A panel from implementors of Service Availability Forum standards showed high interest from academia to work closely with industry parnters. The program was rounded out by two embedded tutorials (Miroslaw Malek on predictive algorithms and Kishor Trivedi on assuring high availability), a tool and demo session and a fast abstracts session (Andras Kövi) as well as a short paper session with practical results presentations. In two special sessions, a European cooperation program on ICT trust, security and dependability (INCO-TRUST) and the Japanese Service Innovation Research Initiative were introduced. Last but not least, two keynotes (Roberto Baldoni, University of Rome, Italy on the Italian e-Government Enterprise Architecture and Hiroshi Maruyama, IBM Japan on Challenges and Opportunities for Computer Science in Service Science) provided an excellent start for two of the three conference days.

The proceedings containing the refereed papers are published by Springer under "Service Availability", Proc. 5th INternational Service Availability Symposium, ISAS 2008, Tokyo, Japan, May 2008; Takashi Nanya, Fumihiro Maruyama, Andras Pataricza, Miroslaw Malek (Eds.); LNCS 5017; Springer Berlin Heidelberg 2008; online: http://www.springerlink.com/content/978-3-540-68128-1/.
