Book Description
The European Conference on Software Architecture (ECSA) is the premier European conference dedicated to the field of software architecture, covering all architectural features of software engineering. It is the follow-up of a successful series of European workshops on software architecture held in the UK in 2004 (Springer LNCS 3047), Italy in 2005 (Springer LNCS 3527), and France in 2006 (Springer LNCS 4344). It evolved into a series of European conferences whose first edition was ECSA 2007, held in Madrid, Spain during September 24–26, 2007 (Springer LNCS 4758). This year’s conference was held at the beautiful Coral Beach Hotel and Resort near Paphos in Cyprus. As with the previous versions of the conference, ECSA 2008 (Springer LNCS 5292) provided an international forum for researchers and practitioners from academia and industry to present innovative research and to discuss a wide range of topics in the area of software architecture. It focused on formalisms, technologies, and processes for describing, verifying, validating, transforming, building, and evolving software systems. Covered topics included architecture modelling, architecture description languages, architectural aspects, architecture analysis, transformation and synthesis, architecture evolution, quality attributes, model-driven engineering, built-in testing and architecture-based support for component-based and service-oriented systems. The conference attracted paper submissions from 29 countries (Australia, Belgium, Brazil, Canada, China, Chile, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Lithuania, Luxembourg, Malta, The Netherlands, Norway, Pakistan, Peru, - land, Portugal, Romania, South Africa, Spain, Turkey, the UK, USA, and Venezuela).

Book Description
Architecting critical systems has gained major importance in commercial, governmental, and industrial sectors. Emerging software applications encompass practicalities that are associated with either the whole system or some of its components. Therefore, effective methods, techniques, and tools for constructing, testing, analyzing, and evaluating the architectures for critical systems are of major importance. Furthermore, these methods, techniques, and tools must address issues of dependability and security, while focusing not only on the development, but also on the deployment and evolution of the architecture. This newly established ISARCS symposium provided an exclusive forum for exchanging views on the theory and practice for architecting critical systems. Such systems are characterized by the perceived severity of consequences that faults or attacks may cause, and architecting them requires appropriate means to assure that they will fulfill their specified services in a dependable and secure manner. The different attributes of dependability and security cannot be considered in isolation for today’s critical systems, as architecting critical systems essentially means finding the right trade-off among these attributes and the various other requirements imposed on the system. This symposium therefore brought together the four communities working on dependability, safety, security, and testing/analysis, each addressing to some extent the architecting of critical systems from their specific perspective. To this end, the symposium united the following three former events: the Workshop on Architecting Dependable Systems (WADS); the Workshop on the Role of Software Architecture for Testing and Analysis (ROSATEA); and the Workshop on Views on Designing Complex Architectures.

Book Description
This monograph presents original research results on selected problems of dependability in contemporary Complex Information Systems (CIS). The ten chapters are concentrated around the following three aspects: methods for modelling of the system and its components, tasks – or in more generic and more adequate interpretation, functionalities – accomplished by the system and conditions for their correct realization in the dynamic operational environment. While the main focus is on theoretical advances and roadmaps for implementations of new technologies, a much needed forum for sharing of the best practices is also presented. CIS systems, being the most complex yet most reliable technical structures engineered by man, present many challenges throughout their lifecycle. Difficulties in modelling, design, implementation and maintenance come not only from involved, widely distributed technical and organizational structures (comprising both hardware and software resources), but even more from complexity of the information processes (data processing, monitoring, resource allocation, dynamic reconfiguration, etc.) which are realized in the operational, often hostile environment. Furthermore, all the issues need to be dealt with taking into account a number of additional factors, such as uncertainties of human interactions, safety criteria and security demands or economic and environmental constrains.

Book Description
The resilience of computing systems includes their dependability as well as their fault tolerance and security. It defines the ability of a computing system to perform properly in the presence of various kinds of disturbances and to recover from any service degradation. These properties are immensely important in a world where many aspects of our daily life depend on the correct, reliable and secure operation of often large-scale distributed computing systems. Wolter and her co-editors grouped the 20 chapters from leading researchers into seven parts: an introduction and motivating examples, modeling techniques, model-driven prediction, measurement and metrics, testing techniques, case studies, and conclusions. The core is formed by 12 technical papers, which are framed by motivating real-world examples and case studies, thus illustrating the necessity and the application of the presented methods. While the technical chapters are independent of each other and can be read in any order, the reader will benefit more from the case studies if he or she reads them together with the related techniques. The papers combine topics like modeling, benchmarking, testing, performance evaluation, and dependability, and aim at academic and industrial researchers in these areas as well as graduate students and lecturers in related fields. In this volume, they will find a comprehensive overview of the state of the art in a field of continuously growing practical importance.

Quality attributes, such as performance or reliability, are crucial for the success of a software system and largely influenced by the software architecture. Their quantitative prediction supports systematic, goal-oriented software design and forms a base of an engineering approach to software design. This thesis proposes a method and tool to automatically improve component-based software architecture (CBA) models based on such quantitative quality prediction techniques.

Book Description
Over the last two decades, a major challenge for researchers working on modeling and evaluation of computer-based systems has been the assessment of system Non Functional Properties (NFP) such as performance, scalability, dependability and security. In this book, the authors present cutting-edge model-driven techniques for modeling and analysis of software dependability. Most of them are based on the use of UML as software specification language. From the software system specification point of view, such techniques exploit the standard extension mechanisms of UML (i.e., UML profiling). UML profiles enable software engineers to add non-functional properties to the software model, in addition to the functional ones. The authors detail the state of the art on UML profile proposals for dependability specification and rigorously describe the trade-off they accomplish. The focus is mainly on RAMS (reliability, availability, maintainability and safety) properties. Among the existing profiles, they emphasize the DAM (Dependability Analysis and Modeling) profile, which attempts to unify, under a common umbrella, the previous UML profiles from literature, providing capabilities for dependability specification and analysis. In addition, they describe two prominent model-to-model transformation techniques, which support the generation of the analysis model and allow for further assessment of different RAMS properties. Case studies from different domains are also presented, in order to provide practitioners with examples of how to apply the aforementioned techniques. Researchers and students will learn basic dependability concepts and how to model them using UML and its extensions. They will also gain insights into dependability analysis techniques through the use of appropriate modeling formalisms as well as of model-to-model transformation techniques for deriving dependability analysis models from UML specifications. Moreover, software practitioners will find a unified framework for the specification of dependability requirements and properties of UML, and will benefit from the detailed case studies.
