As software systems become increasingly ubiquitous issues of dependability become ever more
crucial. Given that solutions to these issues must be considered from the very beginning of the
design process it is reasonable that dependability and security are addressed at the
architectural level. This book has originated from an effort to bring together the research
communities of software architectures dependability and security. This state-of-the-art survey
contains expanded and peer-reviewed papers based on the carefully selected contributions to two
workshops: the Workshop on Architecting Dependable Systems (WADS 2008) organized at the 2008
International Conference on Dependable Systems and Networks (DSN 2008) held in Anchorage
Alaska USA in June 2008 and the Third International Workshop on Views On Designing Complex
Architectures (VODCA 2008) held in Bertinoro Italy in August 2008. It also contains invited
papers written by recognized experts in the area. The 13 papers are organized in topical
sections on dependable service-oriented architectures fault-tolerance and system evaluation
and architecting security.
