For the success and adoption of web services it is essential that not only functional concerns (FC) are addressed but also non-functional concerns (NFC) such as security, reliable messaging, performance, and availability. The support for non-functional concerns encompasses two aspects: the specification and the enforcement and we focus thereby on two views: the black box view (only the interface) and the gray box view (the internal process of a composite service).In this paper we identify the most important requirements for the specification and enforcement of NFCs whilst taking the two different views into account. Furthermore, we present a thorough analysis of the state-of-the-art works based on those requirements and identify areas where future work has to be conducted to fulfill all identified requirements.

“…Beisiegel et.al. [6] discussed infrastructure and Quality of Service constraints, and described an SCA policy attachment framework using intents and policy sets, which are standardized in the SCA specifications. For a runtime implementation of an SCA policy framework, Apache Tuscany [7] is one of the SCA runtimes and it includes an implementation of SCA policies.…”

Service Component Architecture (SCA) defines a component model that allows for a late binding with a concrete implementation. Similarly, the SCA policy framework defines a policy mechanism that uses intents, which are high-level declarations of desired nonfunctional features that are bound to concrete policies at a later time. The definitions of intents are simple, but the actual intent application is complex. Meeting policy requirements requires application of intents at many points in an assembly, and presumes domain knowledge about the semantics and constraints related to using a particular combination of intents. We propose patternbased policy configuration to resolve these difficulties. Our proposed configuration system has two features: policy intent patterns and pattern application rules. Domain knowledge is encoded as roles and role constraints in policy intent patterns. Pattern application rules can be used to define how patterns are applied automatically. This paper takes the original approach of thinking about policy application from a compositional perspective; this reduces the complexity of meeting nonfunctional requirements for SCA assemblies and provides a validation framework for applied intents.

“…A similar problem occurs when regarding the interaction between different concerns: For advanced security requirements it is necessary to secure the reliable messaging mechanism which is also provided by additional assertions. In the SCA Policy Framework [6] WS-Policy is extended by the capability to specify nonfunctional requirements in terms of intent elements that are realized by concrete actions like encryption.…”

Darmstadt, March 2013 Benjamin Schmeling Acknowledgments My sincere thanks go to Prof. Dr. Mira Mezini and Prof. Dr. Tai for their support and guidance during my Ph.D. work as well as to my colleague Anis Charfi for his advice, guidance and help throughout the rendering of this Ph.D. thesis. He contributed much of his time in fruitful discussion with me about new ideas and their realization. I am also grateful for the excellent support from SAP Research and my colleague Steffen Heinzl for the many valuable discussions on my Ph.D. thesis, and in this regard I would also like to thank Mohamed Aly, Heiko Witteborg, Francesco Novelli and all the other colleagues. My students Rainer Thome, Marko Martin and Ajay Sagar contributed to the work described in this thesis by implementing parts of the modeling tool and code generator in the context of their theses. A well-deserved word of appreciation is also in order for Evelyn Nichols for her efforts to improve my English. Finally, I extend my profound gratitude to my family for their unwavering support throughout my studies, which ultimately helped to make their successful conclusion and this thesis a reality. I authored this paper while working as a research associate at SAP Research, during which time I contributed to projects PREMIUM|Services (01IA08003A) and InDiNet (01IC10S04A) which were partially funded by the German Federal Ministry of Education (BMBF). Hence, I thank the BMBF for its financial support. Abstract In software development, two types of concerns must generally be addressed: functional and non-functional ones. Functional concerns relate to the main or core functionality of a software, whereas non-functional concerns represent quality characteristics of the same. It is widely accepted that the two types of concerns should be strictly separated from one another to increase maintainability, understandability and reusability of a software. In component-based software systems, this strict separation of concerns results in the implementation of the respective concerns as functional as well as non-functional components. From the current perspective, web services are the prevalent technology for implementing such component-based software systems. They adhere to open standards and describe a well-defined interface which is strictly separated from the implementation of the ser...
