The service-oriented architecture (SOA) has been successfully applied in enterprise environments. Due to decentralized set-ups, mergers and acquisitions and organizational boundaries, many enterprises today operate multiple, fragmented and heterogeneous service infrastructures that are administered by different organizational units. This fragmented infrastructure causes service duplication and unnecessary...
Enterprise IT infrastructure incurs many costs ranging from hardware costs and software licenses/maintenance costs to the costs of monitoring, managing, and maintaining IT infrastructure. The recent advent of cloud computing offers some tangible prospects of reducing some of those costs; however, abstractions provided by cloud computing are often inadequate to provide major cost savings across the...
In this work, we present Media-Aware Workflows, an extension to Business Process Management Systems (BPMS) and Service Oriented Architecture (SOA) middleware for automating media workflows. The combination of SOA and BPMS technologies provides a robust architectural approach for integrating and orchestrating the multiple heterogeneous systems involved in enterprise-level workflows. However, media-intensive...
Coordination and operational bodies involved in maritime surveillance need a common integrated maritime picture for performing their duties in an effective and cost-efficient way. Emerging trends for building an integrated maritime picture are focused on the adoption of a network-centric approach by leveraging on Service Oriented Architecture models and technological standards. This work presents...
For aspect oriented Web service orchestration, there are two major problems, aspect determination and crosscutting base with aspect. Contrary to other researches focusing on implementation, this paper presents an aspect oriented design method, Themes4BPEL. The novelty of this approach is that it includes five rules to differentiate aspect from base with three views analysis. And the test cases for...
With the advent of Web services and SOA (service-oriented architecture), it seems to be feasible to realize EAI (enterprise application integration) and automatic inter-enterprise interactions. This paper combines SOA and Web service technology which simplify the application integration into the development and using of services, solve the connectivity of the isomerous platform, security, and the...
The UNICORE grid system provides a seamless, secure and intuitive access to distributed grid resources. In recent years, UNICORE 5 is used as a well-tested grid middleware system in production grids (e.g. DEISA, D-Grid) and at many supercomputer centers world-wide. Beyond this production usage, UNICORE serves as a solid basis in many European and International research projects and business scenarios...
Current fashion systems to interconnect large software architectures are moving toward SOA based solutions. This new paradigm for designing system can be improved, in our opinion, by using semantics. Semantics can a play a main role in boosting interoperability thanks to current technologies to express knowledge and to describe semantic Web services (SWS). This paper tackles the provision of a Software...
Many Web services are expected to run with high degree of security and dependability. To achieve this goal, it is essential to use a Web-services compatible framework that tolerates not only crash faults, but Byzantine faults as well, due to the untrusted communication environment in which the Web services operate. In this paper, we describe the design and implementation of such a framework, called...
