From Web Services to OGSA: Experiences in Implementing an OGSA-based Grid Application
نویسندگان
چکیده
In previous work we have presented the ZENTURIO experiment management system for performance and parameter studies of parallel and distributed applications on cluster and Grid architectures. In this paper we describe experiences of an on-going work, targeting the implementation of ZENTURIO on top of the Open Grid Services Architecture (OGSA). We analyse the opportunities offered by a Web services toolkit to develop Grid services as required by OGSA and compare them with the solutions offered by the Open Grid Services Infrastructure (OGSI) specification. Issues regarding proxy management, service lifecycle, UDDI service repository, firewall management, Factory and Registry services, service throughput, and security are comparatively analysed in both implementations.

متن کاملTowards a Market-Centric OGSA-Compliant Architecture Model
The Open Grid Services Architecture (OGSA) provides a high-level framework for service-oriented grid architecture, mostly based on web service standards. The vision of a worldwide computing grid evokes the scenario of electronic markets for grid services. The object of our investigation is a serviceoriented grid architecture model that is compliant with the OGSA specification. We address the pr...
متن کاملGrid Enabling Your Data Resources with OGSA-DAI
OGSA-DAI (Open Grid Services Architecture Data Access and Integration) provides an extensible software framework allowing data resources, such as files, relational and XML databases, to be exposed through Web services acting within collaborative Grid environments or, more modestly, in stand-alone mode. OGSA-DAI may be deployed to WSRF-based platforms, such as the Globus Toolkit 4, as well as no...
متن کاملTowards a Decision Framework for the Use of Multiagent Systems in OGSA Compliant Grid Middleware
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...
متن کاملGrid Web Services and Application Factories
This paper describes an implementation of a Grid Application Factory Service that is based on a component architecture that utilizes the emerging Web Services standards. The factory service is used by Grid clients to authenticate and authorize a user to configure and launch an instance of a distributed application. This helps us solve the problem of building reliable, scalable Grid applications...
