“…These variants are typically generated from the same source code at provider side. We can use generators, inheritance, polymorphic, or product line approaches to generate variants of a service at design time [3,9,20,21]. In [3], we discuss how different variants can be offered based on a feature set from the same code base and benefits achieved using variability.…”

“…Consumers want to fine tune services according to their needs and will get a unique behaviour, which is tailored (personalised) for their requirements. Fine-tuning depends on available features of the services, where a feature is a domain-abstraction used to describe commonalities and differences [3].…”

Abstract. Service-oriented computing (SOC) increases flexibility of IT systems and helps enterprises to meet their changing needs. Different methods address changing requirements in service-oriented environment. Many solutions exist to address variability, however, each solution is tailored to a specific problem, e.g. at one specific layer in SOC. We survey variability mechanisms from literature and summarize solutions, consequences, and possible combinations in a pattern catalogue. Based on the pattern catalogue, we compare different variability patterns and their combinations. Our catalogue helps to choose an appropriate technique for the variability problem at hand and illustrates its consequences in SOC.

“…In [17], Papazoglou suggests that we need to extend basic SOA and presents an extended SOA, which consists of different layers but variability was out of scope of the paper. In [18], Apel et al motivate to use feature-based approach for the development of SOA and to provide variability. They highlight expected benefits and future research challenges of features and services.…”

Abstract-Service-oriented computing has gained attention from researchers and industry due to various benefits. Enterprises are supported by SOC-based solutions. Enterprise requirements change with the customer needs, market conditions, and variability is often needed in SOC. Research usually focuses at variability on the business process level and ignores variability at other layers. In this paper, we show what kind of variability can occur and how it spans across all layers of SOC. We present some example scenarios to discuss different kinds of variability and their reasons in SOC environments. Finally, we classify variability to show that variability is not an isolated problem in a single layer.

“…As non-functional requirements are often applicationspecific and pervasive, a software service is required to allow on-demand integration of tailorable features. To fit those varying requirements recent trends in service engineering aim to combine the benefits of feature-based and servicebased approaches [3,13,1,16]. This combination offers a modular and pluggable solution that increases the reusability of services and supports on-demand customization tailored to the user's needs.…”

Abstract. Companies offering software services to external customer organizations must ensure that the non-functional requirements of all these customer organizations are satisfied. However, in such a cross-organizational context where services are provided and consumed by different organizations, the implementation of features, for example security, is scattered across the services of the different organizations and cannot be condensed into a single module that is applicable to multiple services.In this paper we present an aspect-based coordination architecture for dynamic composition of cross-organizational features in distributed software systems such as systems of systems or service supply chains. The underlying approach of this architecture is to specify the features at a higher level that abstracts the internal mechanism of the organizations involved. A coordination middleware dynamically integrates the appropriate features into the service composition, driven by metadata-based user preferences.
