This poster introduces the Grid-based IT’s applications which are designed and developed to improve the service quality by using Grid technology. During the last several years, the Grid technology had focused on the science application field like ST, NT and BT, but recently is extended to IT area and is used in various fields by integrating with IT technology. We developed Grid-based prototypes...

The QoS attributes of Grid services play important roles in several tasks in Grid computing such as QoS-aware service composition, service negotiation, resource management, service discovery and scheduling. By considering the dynamic aspects of the Grid environments and also the uncertainty related to Grid services, in this paper, we present BNQM, a Bayesian network based probabilistic QoS Mode...

Implementing and using Grids requires a suitable Grid middleware. A reference model for the architecture of Grid middleware is the Open Grid Service Architecture (OGSA) which proposes a service-oriented architecture based on Web service technologies. As a consequence, the potential of such OGSA compliant Grid middleware is limited by the capabilities of Web service technologies. Recently, multi...

Grid services have come to represent the synthesis of web services and grid computing paradigms. Web services provide the means to modularize software is a way that supports their description, discovery and synthesis. Grid computing removes the binding between functional components and specific hardware, enabling software to be deployed dynamically over a network (e.g. intra-, extraor inter-net...

We propose a composable, loosely coupled Service-Oriented Architecture for middleware-independent Grid job management. The architecture is designed for use in federated Grid environments and aims to decouple Grid applications from Grid middlewares and other infrastructure components. The notion of an ecosystem of Grid infrastructure components is extended, and Grid job management software desig...

This article provides an overview of the current Grid Service deployment problems and proposes a general multi layer architecture for service deployment solutions based on the previously published specialised and partially defined ones. From the architectural point of view a service could be a legacy code wrapped to a service oriented environment, a Web service or a Grid service.

Effective and efficient Quality of Service (QoS) management is critical for a service grid to meet the requirements of both grid users and service providers. We incorporate QoS management into Open Grid Services Architecture (OGSA) and provide a high-level middleware to build complex applications with QoS guarantees. We introduce a scalable framework of information service in which capabilities...

The BIS-Grid project, as part of the German D-Grid initiative, investigates service orchestration using Grid service technologies to show how such technologies can be employed for information systems integration, especially when crossing enterprise boundaries. Small and medium enterprises will be enabled to integrate heterogeneous business information systems and to use external resources and s...

Considering the autonomy of resources in the grid environment and based on the service-oriented thought, a resource management system for grid computing can be abstracted to a multi-agent system that consists of service requestor agents, service provider agents and service broker agents. For looking into the interaction characteristics of agents, the formal method is adopted. Firstly, we presen...

Grid is a newly developed technology for complex system with large-scale resource sharing, wide-area communication, multiinstitutional collaboration, etc. A service-based approach for Grid can improve the extensibility and interoperability. In this paper, Service Oriented Grid Hierarchical Architecture is proposed within the OGSA framework, which gives a new approach to build the Grid. The need...
