Call details
============
While computing is provided by the cloud and services increasingly pervade our daily lives, dependability is no longer restricted to mission or safety critical applications, but rather becomes a cornerstone of the information society. Unfortunately, heterogeneous, large-scale, and dynamic software systems that typically run continuously, often tend to become inert, brittle, and vulnerable after a while. The key problem is that the most innovative systems and applications are the ones that also suffer most from a significant decrease in dependability when compared to traditional critical systems, where dependability and security are fairly well understood as complementary concepts and a variety of proven methods and techniques is available today. In accordance with Laprie we call this effect the dependability gap, which is widened in front of us between demand and supply of dependability, and we can see this trend further fueled by the demand for resource awareness (including green computing) and increasing cost pressure.

Among technical factors of dependability, software development methods, tools, and techniques contribute to dependability, as defects in software products and services may lead to failure and also provide typical access for malicious attacks. In addition, there is a wide variety of fault tolerance techniques available, including persistence provided by databases, replication, group communication, transaction monitors, reliable middleware, cloud infrastructures, and trustworthy service-oriented architectures with explicit control of quality of service properties. Furthermore, adaptiveness is envisaged in order to react to observed, or act upon expected changes of the system itself, the context/environment (e.g., resource variability or failure/threat scenarios) or users' needs and expectations. Provided without explicit user intervention, this is also termed autonomous behavior or self-properties, and often involves monitoring, diagnosis (analysis, interpretation), and reconfiguration (repair). In particular, adaptation is also a means to achieve dependability in a computing infrastructure with dynamically varying structure and properties.

Topics of interest
==================
* Architectural and infrastructural principles for adaptive and dependable distributed systems.
* Adaptivity and dependability in service oriented architectures.
* Trust and dependability as complementary and competing aspects. Integration of security and dependability concepts. Balancing and negotiation of dependability and security properties.
* Dependability in complex service oriented environments, GRID-computing, and P2P-systems. Concertation, orchestration, coordination, and context-awareness (context-modeling).
* Middleware support for reunification of network segments and reconciliation of divergent replicas. Consideration of alternative techniques for dynamic configuration and/or reconfiguration.
* New middleware protocols, that are able to work in a peer-to-peer manner in cross-organisational environments and to tackle the challenges of massive scale and mobility.
* Data replication strategies, interfaces, and standards. Interaction of distributed databases with middleware systems.
* Adaptive, optimistic replication models and protocols.
* Group communication and group membership services in failure scenarios with network partitions.
* Other fault tolerance techniques, including transactions and explicit control of quality of service properties.
* Intrusion tolerance techniques.
* Autonomous behaviour and self-* properties.
* Partial and probabilistic approaches for replication, group membership, and distributed consensus in loosely-coupled and ad-hoc environments to improve dependability.
* Support for dependability and adaptiveness in component-based systems (e.g. component frameworks, container services, deployment, composition and substitution of components, building trusted systems from untrusted components).
* Trading of dependability and adaptability with other non-functional requirements like integrity (consistency) or performance. Approaches to improve the scalability of dependable and adaptive systems.
* Foundations and formal methods (e.g., rigorous development of dependable systems, verification and refinement of fault tolerant systems, techniques and mechanisms ensuring application level fault tolerance).
* System design, modeling, development and tool support for dependable and adaptive systems.
* Evaluation and experience reports of dependable and adaptive distributed systems and services.
* Holistic dependability approaches: Social, cultural, psychological, economical, managerial, and educational aspects of dependability.
