The Landscape of Service-Oriented Systems: A Research Perspective

Innovations in Information Technology ( …, 2012

Service-oriented software engineering (SOSE) is a software engineering approach for building service-oriented solutions by utilizing service-oriented computing paradigm constructs and concepts. Different methods exist to develop service-oriented software. However, no standardized set of service-oriented principles has been defined yet. This paper surveys current principles and provides a comparison framework to identify which are most considered by different SOSE methods at various stages of solution life cycle.

Some IT companies, such as IBM, are pushing research and education in Service Science. This is due to the transition of their business models from producing hardware and software to providing services, as well as service-oriented vision changes the way people design software systems. People believe that service is the common language between business developers and IT engineers and service bridges the gap between business requirements and IT implementation. But people still do not know clearly how to use the service related theories in software system analysis and design. This paper attempts to explore this unknown topic. We want to reveal how software can become a service and suggest guidelines for analyzing and implementing service-oriented systems.

Service computing has become the new frontier of enterprise computing in the continued pursuit of organizational agility. Many major corporations are in the midst of implementing significant initiatives to re-architect their IT through service computing to help meet fast changing business requirements. As a result, many new and interesting research questions arise in this area, spanning from technical to organizational to economic issues. Currently, there is a great need for a framework for aligning the issues of technology and management in the era of service computing. This panel advocates that the MIS community should embark a concerted effort in this direction. The panelists will present their positions and insights and discuss why and how MIS should take leadership in this research area. The specific objectives of this panel include: (1) Discuss issues towards a unified framework for service computing and management. (2) Identify research issues dealing with challenges enterprises must confront in the era of service computing.

In this article we review the metaphor of service-oriented architecture for enterprise computing. In typical definitions service-oriented architecture appears as a single message and a consistent roadmap for building flexible software system landscapes. But it is not. Different communities have elaborated different SOA (service-oriented architecture) concepts to address different problem areas, i.e., enterprise application integration, business-to-business, business process management, and software productizing. If software architects and software managers are aware of these strands of SOA when talking about SOA in their projects they can avoid misunderstandings and detours better. This article contributes a clarification of the different strands of SOA concepts and technologies and their mutual dependencies and identifies particular SOA concepts as instances of more general software engineering principles.

Method engineering techniques albeit proven effective for paradigms such as function, object and component, are pertinent to limited aspects of service orientation (SO). The comparison frameworks show that the pro- duced methods neither conform to SO design principles nor to SOA, which is an issue. This paper proposes a framework to guide engineering methods for service-oriented software engineering. It describes a method by its aggregates and the relationships between elements such as Service Science (SS), SO, SOA, SOC, and Web. The paper also describes the guidance for method engineering. The framework consists of two layered categories of entities: (C1) conceptual foundation entities: SS, SO, and SOA, and (C2) realization infrastructure entities: SOC and Web. These entities request and provide services from/to each other. The framework comprehensively describes the SOSE environment, enforces the construct service with fundamental properties and principles, produces SOSE methods t...

Abstract—A critical issue in the design and construction of any complex software system is its architecture. Software architecture as an important column of software development process has various methods and roadmaps that all of them have some common principles and inception. Architecture-based approaches have been promoted as a means of controlling the complexity of systems construction and evolution.

To survive in the global marketplace, organizations need to continually adapt to the changing business environment. Information systems play an ever increasing role in helping organizations achieve this objective. Recently, there has been considerable attention paid to the service orientation and how it could alter the way organizations function and their relationships with business partners such as suppliers. In this research, we focus on service-oriented enterprises and architectures. In doing so, we bring to the fore the current state of the art in the emerging service paradigm. Service-oriented computing is revolutionizing the way corporations manage information so as to enable streamlining the various stages of computing including strategic planning, business process management, operations processing, and information technology services. We demonstrate how the application of service orientation to a supply chain will lead to service-centric supply chains that offer significantly more enterprise agility. We also discuss opportunities for future research in the new paradigm.

The rationale behind service oriented computing is to lift inter-organisational integration on a higher level of effectiveness and efficiency. E-services promise to offer means for floating modularisation of arbitrary organisational assets into components that can be dynamically offered, discovered, negotiated, accessed and composed in an open environment. From a technical point of view electronic services are software systems that have

Service-oriented System engineering (SOSE) and traditional software engineering mainly differ for their focus and aims. These differences are reflected by a number of aspects peculiar to SOSE (service aspects). In this paper we specifically discuss three service aspects: the relevance of cross-organizational collaboration, increased importance of the identification of stakeholders, and the need for increased effort at run-/change time. We argue that SOSE methodologies provide better guidance on their application when service aspects are emphasized in associated process models. By highlighting the three service aspects in a process model of the methodology defined in a large European project, we show specifically how each aspect provides guidance for engineering service-oriented systems in practice.
