Offering applications as a service in the Cloud builds on the notion of application multi-tenancy. Multi-tenancy, the sharing of application instances and their underlying resources between users from different organizational domains, allows service providers to maximize resource utilization and reduce servicing costs per user. Realizing application multi-tenancy however requires suitable enabl...

Challenges of enterprise distributed system development. Enterprise distributed systems (such as air traffic management systems, cloud computing centers, and shipboard computing environments) are steadily increasing in size (e.g., lines of source code and number of hosts in the target environment) and complexity (e.g., application scenarios). To address challenges associated with developing nex...

Many organizations have now adopted Service Oriented Architecture (SOA) as an architectural style to help them with architecture, design and implementation of their core services and systems. Most of these organizations are challenged in integrating SOA style with their overall Enterprise Architecture work. This framework links an SOA style with the Enterprise Architecture (EA) methodologies to...

This paper investigates how Enterprise Architecture (EA) evolves due to emerging trends. It specifically explores how EA integrates the Service-oriented Architecture (SOA). Archer’s Morphogenetic theory is used as an analytical approach to distinguish the architectural conditions under which SOA is introduced, to study the relationships between these conditions and SOA introduction, and to refl...

In enterprise applications, regulatory and business policies are shifting their semantic from access to usage control requirements. The aim of such policies is to constrain the usage of groups of resources based on complex conditions that require not only state-keeping but also automatic reaction to state changes. We argue that these policies instantiate usage control requirements that can be e...

Service-Oriented Architecture has gained considerable attention in construction of enterprise level business solutions. Although this architectural approach provides many benefits, it comes at the cost of increased complexity. This research focuses on the development of a metadata framework using semantic web technologies of XML, Resource Description Framework (RDF) and Web Ontology Language (O...

Service-oriented architecture is nowadays widely adopted as modern approach for development of enterprise-wide and cross-enterprise distributed applications. From the software engineering point of view, these applications resemble some features of formerly known component-based and object-oriented software systems and web applications, but the differences are substantial enough to make it impos...

To attain interoperable business service collaborations, the nature and concepts of service-oriented inter-enterprise environments must be carefully analysed and formalized. Moreover, development tools and runtime infrastructure services are needed for establishing a sustainable business service ecosystem that provides interoperable business service delivery. The research proposal introduced in...

The field of enterprise architecture attracted the attention of the research community for the first time when Zachman introduced the Framework for Information Systems Architecture in 1987. However, it was not until 1996 that enterprise architecture emerged as an active field of business activity and research. Enterprise architecture (EA) is important because organizations need to adapt with in...

In the current economic context, enterprises are struggling to obtain competitive advantages on the market, by exploiting the opportunities offered by information technology. The research in this paper aims to encourage the use of modern approaches in order to increase enterprise agility, through the transition to Service-Oriented Enterprise (SOE). The proposed solution is based on reaching a s...
