  1. SIMDAT Architecture Mike Boniface IT Innovation Centre GGF16 Grid Architecture Experts Workshop 14 February 2006 Athens

  2. IST EU SIMDAT Project Seven Grid-technology development areas: Grid infrastructure Distributed Data Access VO Administration Workflows Ontologies Analysis Services Knowledge Services Four sectors of international economic importance: Automotive Pharmaceutical Aerospace Meteorology

  3. End Users Grid Technologists Capability Providers SIMDAT Partners

  4. Demanding Application Drivers • Integration of the product design process chain (CAE/CAD/CAT) including external engineering companies, developers and suppliers • Multi-disciplinary collaborative configuration design of complex aerospace products • Drug discovery environment managing the distribution of both public and commercial bioinformatics data and analysis services • Virtual Global Information System Centre supporting the distribution and integration of large scale meteorology data providers

  5. We need to support dynamic business models • SIMDAT users’ are driving architectural requirements for Grid trust and resource management • Generic business collaboration patterns identified • Analysis service provision • Data publication/subscription • Brokering/Supply chain • Grid license distribution • Focus on export policies for IPR management and economics is critical • Many functional services exist but tend not to be designed to be constrained in this way...

  8. Functional Business Models SIMDAT Interfaces Problem Solving Environments BPEL/DPML/SCUFL Workflow JSDL/UDAP OGSA-DAI UDDI, ebXML, OWL-S Information Data Execution Management WSDM/WS-Agreement WS-Trust, WS-... Security Resource Management WS-I/WSRF Core

  9. GRIA Overview • Open source Grid middleware aimed at supporting B2B collaborations • V4.3.0 has easy-to-use yet powerful functionality • business-to-business accounting and QoS services • distributed file transfer, storage and processing • OGSA-DAI database services (new in GRIA v4.3) • Taverna workflow tools and service also available separately • Off the shelf security components • transport and message level security • dynamic authorisation linked to business processes and trust • firewall friendly • Standards compliance • WS-I Basic Profile and WS-I Basic Security Profile

  10. GRIA’s dynamic federation user-driven, transient no prior infrastructure optimises provider-consumer value exchanges Service Level Agreements regulate use of resources replace VO-level controls Good for fast collaborations market-based services lightweight, short-lived project collaborations “Fast” Virtual Organisations Service Level Agreement

  11. GRIA Developments for 2006 in SIMDAT and Other Projects • GRIA 5.0 (Q1 2006) • Standardised message structure including WSRF and WS-I doc/literal profile. • Dynamic Contextualised Security based on WS-Trust/WS-Federation security token patterns • End-to-end accounting services supporting service provider/client liabilities, client side aggregation and account token issuing/verification • Simplified quality of service model based on SLAs offering coarse grained resource promises and softer cut-offs. • GRIA 6.0 (Q4 2006) • Dynamic workflow adaptation (GridVM) allowing service providers to publish business process appropriate to business goals that can be enacted by clients at the point of use • Standardised management component allowing service providers to flexibly configure services that are required to fulfil business goals

  12. Conclusions • Grid infrastructure successfully deployed in the 1st phase • Real world application use cases driving architecture and infrastructure developments • Architecture based on Grid solution portfolio • Exploring implications for dynamic trust and resource management
