The management of service oriented architectures demands an efficient control of service users and their authorizations. Similar to structured cabling in LANs, Identity & Access Management systems have proven to be important components of organizations’ IT infrastructures. Yet, due to new management challenges such as virtual organizations, on-demand computing and the integration of third party...

This paper proposes the concept of Inter-Enterprise Architecture (IEA), which seeks the application of tools and methodologies developed in the Enterprise Architecture (EA) field for the individual firm, adapting to an environment of collaboration between several companies that make networks or supply chains, in order to facilitate the integration and interoperability of their collaborative pro...

This paper covers the processes of designing the system architecture and the authoring interface for Pachyderm 2.0, as well as some of the fundamental conceptual strategies that enabled the development of the software. It describes the architecture of the underlying frameworks, applications, and content templates. Areas for potential collaboration and development are identified.

This paper investigates the relationship between ICT architectures and project risk, in the context of the development of large inter-organizational systems. Although previous research has identified ICT architecture as a project risk, the focus has been on technical issues. Expanding this perspective, we investigate how technical architectures have bearings on the organization of projects, whi...

Iaan latest years, the concept of interconnecting clouds to allow common service coordination gained significant attention mainly because of the increasing utilization of cloud resources from Internet users. An efficient common management between different clouds is essential benefit, like boundless elasticity and scalability. Yet, issues related with different standards led to interoperability...

Force (IETF), its Areas, and its Working Groups. (Note that other groups may also distribute working documents as Internet Drafts). Internet Drafts are draft documents valid for a maximum of six months. Internet Drafts may be updated, replaced, or obsoleted by other documents at any time. It is not appropriate to use Internet Drafts as reference material or to cite them other than as a \working...

This article presents a security architecture suitable for implementation of the security services and mechanisms selected by the security policies defined by the ACTS TRUMPET project for an appropriate protection of the external interfaces of TMNs. These security policies define the protection measures to use for communication in the inter-domain management case. These measures need to be impl...

The paper describes an approach for inter-organisational sustainability reporting. This approach is based on an open source software tool “Sustainable Online Reporting Model” developed at the University of Oldenburg. The idea of sustainability reporting across a single reporting entity like a company originated from the field of financial reporting. Later on Kasperzak (2003) presented an approa...

The rapid increase in digital content, specially multimedia, calls now for standardization of Media Cloud and Inter-Cloud computing, for better provisioning of services. InterCloud computing faces some key challenges in terms of handling multimedia, which are discussed in this paper along with our research status towards their solutions. We also present InterCloud basic architecture and Media C...

The question of how a service consumer and a service provider should collaborate with each other in a business-to-business (B2B) setting is an ongoing research issue. The concept of electronic eSourcing (eSourcing) has been proposed as an integral concept for the EU research project CrossWork. The properties of eSourcing have been explored, however, the question arises how a service consumer an...
