This paper argues for the adoption of a information centric system model instead of the current service-oriented one. We present an architecture for a global information storage and dissemination network which provides for efficient interaction and coordination among autonomous actors through a shared information space. We believe that the resulting, loosely coupled systems, while probabilistic...

What is the business value of Service Oriented Architecture? Although the SOA paradigm has become quite evident in IS literature, a comprehensive model of the SOA business value is still lacking. Based on a literature review and on a multitheoretical foundation, drawing on the adoption of innovations literature and on the resource-based view as well as on resource dependency theory, we attempt ...

Technical developments and advancements in the IT industry such as Service Oriented Architecture (SOA) have made businesses more flexible and agile. Adoption of the SOA framework, along with new tools and technologies, has increased enterprise agility and enabled businesses to gain a competitive edge. However, enterprises that are bound to legacy systems are often constrained by the lack of fle...

Since the beginning of the Service-Oriented Architecture (SOA) paradigm, with its various implementation technologies such as Web services, the focus of industrial communities has been on providing tools that would allow seamless and flexible application integration within and across enterprises’ boundaries. In this paper, the authors present a Context-based, Service-oriented Modeling and Analy...

Security is an important aspect of Service-oriented Architectures (SOAs), enabling the service-based integration of partner IT systems across organizational boundaries, i. e., in the Internet of Services. Current trends in SOA security, e. g., reducing it to Web service security, do not take into account SOA-specific threats, vulnerabilities, and attacks. In this paper, measures to support the ...

Component-oriented and service-oriented approaches have gained a strong enthusiasm in industries and academia with a particular interest for service-oriented approaches. The service concept and its use in web-based application development have a huge impact on reuse practices. Accordingly a considerable part of software architectures is influenced; these architectures are moving towards service...

Enterprise Architecture (EA) has undergone many changes since the IT has found its way into enterprises. At the moment the Service-Oriented Architecture (SOA) is being hyped but has also gained some importance. Implementing SOA can have many implications for an enterprise, depending on how visionary the implemented architecture is. This paper provides the description of an enterprise architectu...

As a matter of fact, SOA-based systems have a huge internal complexity due to plenty of services. On the one hand, this complexity enables and strongly supports the flexible alignment of the enterprise architecture with business processes. On the other hand, it requires a special management and control framework – provided by SOA Governance. For IT Governance, many accepted approaches exist. In...
