  1. Grids and Web Services:Summary and Future Plans Tony Hey tony.hey@epsrc.ac.uk

  2. Background ‘Truths’ • Grid Services will be Web Services • When will ‘WS-Grid’ standard be agreed? • UK e-Science Programme 3 years into 5 year programme • OMII must build on foundation that will protect UK investment and users • UK e-Science Programme and GridPP, EGEE and the LCG should coordinate efforts • Very significant scale of investment £250M + €70M

  3. Summary - 1 • EGEE Grid technology strategy is to base EGEE-1 production middleware release development on a ‘core’ Web Services platform • Deliver EGEE-1 to production service implementors end Q4 2004 • Evaluate progress with WSRF in Q1 2005 with view to possible adoption in EGEE-2 release

  4. Summary - 2 • Some members of the UK middleware community should engage with WSRF evaluation and technical debate • Important to maintain coherence of e-Science and Grid communities • Want WSRF debate to address shortcomings in an open standard fashion • GT4.0 will be available for detailed evaluation at end Q3 2004 • Earlier beta version available end Q2 2004 for experimentation

  5. Summary - 3 • To build Web Service compatible Grid middleware now must adopt conservative subset of WS proposals • Explore range of WSRF applicability as well as other ways to handle state and resources • Similar strategy to EGEE and OMII

  6. Summary - 4 • GT3 experiences underline need to protect users from rapid change and immature software ….. • WS-GAF looking at ways of supporting Grid applications using ‘standard’ Web Services • Projects should provide valuable experience on how and when users should move

  7. UK e-Science Timeframes 2001 2002 2003 2004 2005 2006 2007 SR2000 * * * SR2002 * * * SR2004 * * * SJ5/AAA Service * * LHC/LCG *

  8. New JCSR Funding • £3M for Security Development Projects • Combine Shibboleth with PERMIS Authorization Services • Joint project with NSF Internet2 NMI project on Security Services for Virtual Organizations • £3.4M for ‘National Middleware Services’ • Deployment of National Authentication Framework based on Shibboleth • Support both Digital Library and e-Science communities

  9. e-Science beyond 2006 • Grid Operations Centre and National Grid Service • complementary to national supercomputer • Open Middleware Infrastructure Institute • National e-Science Institute • Digital Curation Centre • International Standards Activity

  10. SR2004: Combined OST/JISC Bid • GOC and NGS £3.0M • OMII £5.5M • e-SI £0.5M • DCC £1.5M • Standards £0.5M InfrastructureTotal £11.0M per annum

  11. Concluding Remarks • Grid Services will be Web Services in the future • Important role for GGF in providing focussed forum for international e-Science community • Many other countries now launching ‘e-Science’ programmes modeled on UK initiative • Danger that UK will not build on the emerging e-Science platform with follow-up funding • The e-Science initiative must ultimately be justified by the take-up and results achieved by the scientific community • Need your views about whether we should have identifiable e-Science funding line post 2006

  12. The 2004 e-ScienceAll Hands Meeting • Date: September 1-3 • Place: East Midlands Conference Centre, University of Nottingham • Application details and programme will be on RCUK website: www.rcuk.ac.uk/escience
