In scientific collaboration platforms such as caGrid, workflow-as-a-service is a useful concept for various reasons, such as easy reuse of workflows, access to remote resources, security concerns, and improved execution performance. We propose a solution for facilitating workflow-as-a-service based on Taverna as the workflow engine and gRAVI as a service wrapping tool. We provide both a generic service...
Web service models are increasingly being used in the Grid community as way to create distributed applications exposing data and/or applications through self describing interfaces. Scientific research is one key field in which the benefits are apparent as individual services can be orchestrated into experimental workflows that model the research process and facilitate verification and extension. However,...
Scientific communities are increasingly exposing information and tools as online services in an effort to abstract complex scientific processes and large data sets. Clients are then able to access services without knowledge of their internal workings therefore simplifying the process of replicating scientific research. Taking a service-oriented approach to science (SOS) facilitates reuse, extension,...
caBIGtrade (the cancer Biomedical Informatics Gridtrade) is an open-source, open-access information network enabling cancer researchers to share tools, data, applications, and technologies. caGrid is the underlying service-based grid software infrastructure for caBIG, integrating distributed data and analytic resources into a virtual collaborative platform for cancer research. Within caGrid, many...
Service-oriented architecture represents a promising approach to integrating data and software across different institutional and disciplinary sources, thus facilitating Web-scale collaboration while avoiding the need to convert different data and software to common formats. The US National Cancer Institute's Biomedical Information Grid program seeks to create both a service-oriented infrastructure...
With the emergence of global market and virtual enterprises, coordination of business processes in dispersed organizations by distributed workflow execution will take on more importance. At the same time, grid workflow is now been regarded as a fundamental service in grid environment. In this paper we give a real life example to see how distributed workflow technology can be used in virtual enterprises...
The evolution of grid technologies has brought to the world a loosely coupled environment that enables flexible integration among heterogeneous systems. On building a service-oriented architecture for grid systems, more and more research is focused on service composition, in which workflow and simulation techniques have shown great potential. Simulation of services' interaction is important since...
