Cloud computing is a promising paradigm for the provisioning of IT services. Cloud computing infrastructures, such as those offered by the RESERVOIR project, aim to facilitate the deployment, management and execution of services across multiple physical locations in a seamless manner. In order for service providers to meet their quality of service objectives, it is important to examine how software...
With the rapid growth of available web services developed by different organizations, clustering of web services is required for conveniently managing services such as web services selection, discovery, composition and QoS prediction. However, the traditional clustering approaches have some drawbacks in similarity measuring and information preprocessing. In this paper, a similarity model is presented...
Service-Oriented Computing reveals features which are not commonly found in conventional computing paradigms; loose coupling, dynamism, blackbox, evolvability, and heterogeneity. These features make diagnosing and healing faults found in deployed services and service-related elements more challenging than managing conventional systems. Hence, service-oriented systems management often results in problems...
In the pervasive computing paradigm, there is a strong demand towards user-centric services based on the context and service management. For implementing the user-centric services recent researches on the service-oriented system is focused on the context recognition, analysis and reasoning. Furthermore, the service-oriented systems also need to manage the structural and hierarchical context model...
The following topics are dealt with: business process management; service process; service oriented architecture; cloud service; quality of service; service composition; semantic Web service; service discovery; service delivery; service coordination; service management; service selection; policy driven business process generation; trust management; business process integration; software tool; service...
SOA governance has a critical role in achieving success and realizing the benefits of SOA. Without effective SOA governance, organizations will experience some significant challenges including difficulties in designing effective decision structures and building a SOA roadmap, lack of service funding, lack of consistent governance processes and gap between IT and business. Study of existing SOA governance...
SOA governance has a critical role in achieving success and realizing the benefits of SOA. Without effective SOA governance, organizations will experience some predictable challenges including difficulties in designing effective decision structures and building a SOA roadmap, lack of service funding, lack of consistent governance processes and gap between IT and business. Study of existing SOA governance...
Cloud computing offers the potential to dramatically reduce the cost of software services through the commoditization of information technology assets and on-demand usage patterns. However, the complexity of determining resource provision policies for applications in such complex environments introduces significant inefficiencies and has driven the emergence of a new class of infrastructure called...
We propose a design methodology, Service-Oriented Design with Aspects (SODA), for service-oriented systems to address the need to continually upgrade and evolve services while maintaining various versions. Our approach treats aspects as first-class design elements and consistently applies the concept of aspect to all phases of design and evaluation. At the early design stages, crosscutting concerns...
The following topics are dealt with:service development; service control; service-oriented architecture; business services; cyber-physical services; data-based services; service management; embedded services; service verification; and service analysis.
Service-oriented architectures (SOA) are a promising approach for structuring business information systems.Advantages are interoperability through standardization and adaptability of IT infrastructure to changes in business processes. Successful maintenance of a SOA does not only need technical but also organizational measures. In this paper, we present a process model and an information model for...
The development of enterprise-wide service-oriented architectures (SOA) is a complex task. In most cases, evolutionary approaches are used to deal with the arising complexity. However, most of the existing design methodologies and implementation strategies focus on more technical, service realization specific aspects. Challenges regarding the definition and the management of related service artifacts...

Typical SOA platform orchestrates services centrally, through pre-defined processes, assuming that what should have already been triggered is defined in a process. Thus complex events should trigger a set of services is not accounted for in traditional SOA architecture. Event-driven SOA lets users monitor, analyze, and enrich events to make the connections among disparate events that do not at first...
Ubiquitous connectivity today allows many users to remain connected regardless of location with various kinds of communities. This paper studies challenges in building trusted communities that encompass both new users as well as users already possessing credentials from other well known connectivity providers, federations, content providers and social networks. We postulate that trusted communities...
In the banking sector business requirements continuously change whereas IT infrastructure investments must be amortized over years. This conflict produces very heterogeneous systems. Adopting the SOA / BPM approach helps coping with that complexity. This way, everything is a service, easing composition and integration. On top of that, strict security and reliability requirements exacerbate the need...
In recent few years, a lot of standards and protocols have been proposed for home networks. However, these standards and protocols do not interconnect easily with each others. This paper describes the service discovery and interaction for home network devices using heterogeneous standards and protocols. OSGi was proposed to provide several kinds of services coming from different providers to be loaded...
Service-oriented computing research activities focus on service foundations, service composition, service management and monitoring, and service-oriented engineering. While the precise definition of service foundations including an appropriate general service model is still an open research issue, event and process algebras, Petri nets, and abstract state machines (ASMs) are commonly considered as...
Modern enterprise consists of complicate business systems. The enterprise service-oriented architecture (ESOA) becomes more and more mainstream for designing and implementing enterprise business systems. The purpose of this paper is to build a generic and abstract model of enterprise service-oriented architecture. The model consists of seven sets: services, service consumers, service data, service...
The following topics are dealt with: grid computing; P2P computing; cooperative computing; trustworthy computing; security computing; privacy computing; multimedia services; intelligent systems; wireless networks; sensor networks; ad hoc networks; mobile computing; network computing; service composition; service management; cluster computing; parallel computing; distributed computing; service oriented...
