“…The common approach in SOA to design a large distributed system suggests decomposition of the application logic into small encapsulated standalone units called services responsible for and encapsulating a part of the business domain [4]. For example, in the e-shop system, one service is responsible for the user management, while the other for the product management.…”

“…A service is a reusable, cohesive, managed, deployable, and independent process interacting via messages. [7] [8] [7] SOA suggests a system infrastructure following the structure of the real business [4]. In consequence, when the e-shop has departments responsible for the store (products and stock) and customer service (orders), then these are also components [1], [7] in the system.…”

“…This results from difficult domain decomposition and high information repetition due to significant concerns tangling [3]. Alternatively and more likely, to deliver a highly scalable and distributed system, there exists Service-Oriented Architecture (SOA) [1], [4], [5] decomposing a system into many smaller services following Single Responsibility Principle [6]. However, while this decomposition increases scalability and throughput, its maintenance gets more difficult as the services are more encapsulated, self-standing, isolated, and possibly written in different programming languages, which significantly reduces a possibility of information reuse and forces manual repetition instead.…”

Abstract-Nowadays enterprise software solutions must deal with ever-growing complexity and a multitude of business processes. The mainstream system design decomposes the system into small reusable services. While these services isolate certain system logic and address efficient elasticity towards growing user demands, there are multiple issues related to such a design, such as limitations to deal with restated information, information reuse or the ability to address cross-cutting concerns across multiple services. This paper highlights limitations of service-oriented architecture and proposes an alternative decomposition through aspect-driven service-oriented architecture. Such architecture involves adaptive, context-aware services preserving simple maintenance while addressing information reuse and crosscuts across services. The paper provides a formal description of the proposed architecture as well as a demonstration through a case study, showing approach properties and benefits.

“…Services can be seen as heterogeneous constellations with the characteristics of being produced and consumed at the same time and having a process-like nature, which unfolds over a period of time in a specific context (Perrey & Lycett 2003;Vargo & Lusch 2011;Bask et al 2010;Voss & Hsuan 2009). As an example, a professional consultancy service can be seen as a series of events, occurring between business partners, agreements, deadlines and deliverables.…”

Abstract:This paper seeks to improve the understanding of how service-based companies can benefit from developing and delivering service offerings from a standardised core of service modules, which are organised through a service architecture.Research within the field is relatively sparse and there is scope for an explicit definition of elements related to the development of modular service platforms and architectures. A study of existing literature, combined with a comprehensive case study in a global engineering consultancy, has created the basis for development and evaluation of the conceptual model for modular service design synthesis presented in this paper. The case study is based on internal documentation and a high level of interview data. Inductive research methods have been used for the analysis. The presented conceptual model defines three suggested dimensions (Market Segmentation, Service Roadmap and Service Architecture Layout) to be included in development of modular service platforms and architectures. Testing indicates a significant standardisation potential for service configuration across service families. Our understanding is 3 that the approach can increase strategic flexibility and adaptability to changes in a quick evolving service market. The empirical part of this paper is exploratory in nature and is limited to one provider of high-end engineering consultancy services. Thus, further research will be needed to verify the aspects of the presented methodology to allow a further generalisation of our findings.Nevertheless, this paper contributes to the emerging literature on service modularity by presenting a specific operational approach for description and utilisation of modular service platforms and architectures.

Abstract. The development of intelligent environments poses complex challenges, namely at the level of device heterogeneity and environment dynamics. In fact, we still lack supporting technologies and development approaches that can efficiently integrate different devices and technologies. In this paper we present how a recent integration of two important technologies, OSGi and Jade, can be used to significantly improve the development process, making it a more dynamic, modular and configurable one. We also focus on the main advantages that this integration provides to developers, from the Ambient Intelligence point of view. This work results from the development of two intelligent environments: VirtualECare, which is an intelligent environment for the monitorization of elderly in their homes and UMCourt, a virtual environment for dispute resolution.
