The Wide Area Grid CNES experiment Current Status and Plans, CNES, Paul Kopp,WGIS24
Architecture Study – Major Highlights • Architecture study - Major highlights • Use of the IAF methodology (Integrated Architecture Framework) • methodology based on view points & abstraction layers • Objective of the study • identify the technical elements necessary to complete the WAG • identify a mechanism for service publication • identify a portal for access to the WAG • identify a generic business process management • identify a mechanism of transfer and visualization of service results • Main conclusions • WAG logical components are well identified • data flow between components are well identified • recommended standards: • Services: OGSA Web Service Resource Framework and OGSA Web Service Notification • WAG portal: JSR 168 • Task chaining: Business Process Execution Language (BPEL4WS ou WS-BPEL), Job Submission Description Language • Security: X.509 Paul Kopp – WGISS 24 – October, 2007
Next Steps WAG-1 2008: Install a WAG prototype with interested agencies • collect comments from CEOS agencies regarding the architecture study (some comments already received from NSAU and RSGS) • specify the WAG architecture • based on the existing architecture study • after having taken into account the comments received from CEOS agencies • deploy the WAG with its test beds • collect lessons learnt from the WAG prototype experimentation Stakes • If the experimentation is OK, the WAG architecture could be recommended for the implementation of interoperable systems, e.g. in the frame of the International Charter on Space and Major Disasters • The Wide Area Grid concept could be a contribution from CEOS to GEO WAG-2 Paul Kopp – WGISS 24 – October, 2007
GRIA Context • CNES has been experimenting several Grid middelware • Globus • Synfiniway (Fujitsu) • gLite • and now GRIA GRIA was originally developed during the IST GRIA project (Grid Resources for Industrial Application, About GRIA • Origin: University of Southampton IT Innovation Centre (UK) • GRIA is a service-oriented infrastructure designed to support B2B collaborations • GRIA is available free and open source • makes use of standards that can be used in B2B scenarios • more about GRIA: http://www.gria.org/about-gria/overview GRIA at CNES • currently running on 3 machines for testing • preliminary result: in comparison with other middlewares, firewall crossing is much easier • more detailed report by CNES at WGISS25 Paul Kopp – WGISS 24 – October, 2007
