As software systems become ubiquitous, the issues of dependability become more and more crucial.

This book was born of an effort to bring together the research communities of software architectures and dependability.

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...
