Distributed systems are at the core of the information society, ranging from everyday's applications such as banking or health care to highly specialised systems used in automation, transportation, and air traffic control. The key element for achieving scalable and maintainable distributed software systems is dependability, because otherwise the complexity of distribution would leave the system brittle, vulnerable, and uncontrollable at the end.

DeDiSys provides concepts for optimized dependability for two classes of distributed systems: Tightly coupled, data-centric systems such as distributed object systems and loosely coupled, service-oriented systems such as Web service based Grid systems or peer-to-peer systems.
