2 Enabling Grids for E-sciencE INFSO-RI EGEE and the National Grid Service EGEE Induction, 8 December 2004, NeSC 2 Acknowledgements This talk was prepared by Mike Mineter of NeSC and includes slides from talks delivered by: –Neil Geddes, GOSC Face-to-Face, NeSC, November 2004 –Andy Richards, GOSC Face-to-Face, NeSC, November 2004 –Tony Hey, AHM 2004, Nottingham,

3 Enabling Grids for E-sciencE INFSO-RI EGEE and the National Grid Service EGEE Induction, 8 December 2004, NeSC 3 Goals of this module To outline the National Grid Service To summarise its relationship with EGEE

4 Enabling Grids for E-sciencE INFSO-RI EGEE and the National Grid Service EGEE Induction, 8 December 2004, NeSC 4 Contents Snapshots of the UK e-infrastructure The UK e-Science programme The National Grid Service The NGS and EGEE

5 Enabling Grids for E-sciencE INFSO-RI EGEE and the National Grid Service EGEE Induction, 8 December 2004, NeSC 5 Snapshots of UK e-infrastructure The JISC view Digital curation Networks –Weve been (mainly) ignoring networks today! –A sign of their success!! Grids

6 6 The JISC Communities Portals Applications Content Meta Data & Delivery tools Finding /Access tools E-learning Digital librariesE-research Internet AAA Services

7 7 Digital Curation Centre Actions needed to maintain and utilise digital data and research results over entire life- cycle –For current and future generations of users Digital Preservation –Long-run technological/legal accessibility and usability Data curation in science –Maintenance of body of trusted data to represent current state of knowledge in area of research Research in tools and technologies –Integration, annotation, provenance, metadata, security…..

12 Enabling Grids for E-sciencE INFSO-RI EGEE and the National Grid Service EGEE Induction, 8 December 2004, NeSC 12 The UK e-Science programme Goal Where we are today Web services and Grids

13 Enabling Grids for E-sciencE INFSO-RI EGEE and the National Grid Service EGEE Induction, 8 December 2004, NeSC 13 The UK e-Science programme We are attempting to build an infrastructure comprised of a set of middleware services capable of supporting the dynamic 'virtual organisations' required by scientists, engineers and industry. As a shorthand for this core middleware infrastructure I often use the controversial term Grid Professor Tony Hey, September 2004 £250M UK e-Science Initiative

15 Tony Hey, AHM Web Services and Grids Computing models developed for sequential machines led to the distributed object model of distributed computing represented by Java and CORBA Experience has shown that the distributed object model ties distributed entities together too tightly Resulted in fragile distributed software systems when going from LANs to WANs Replace distributed objects by services connected by one-way messages and not by request-response messages IT industry has united around Web Services

16 Tony Hey, AHM The Web Services Magic Bullet Web services Company A (J2EE) Company B (ONE) Company C (.Net)

17 Tony Hey, AHM WS-I+ profile Web Service Grids: An Evolutionary Approach WS-I Standards that have broad industry support and multiple interoperable implementations Specifications that are emerging from standardisation process and are recognised as being useful Specifications that have/will enter a standardisation process but are not stable and are still experimental

18 Tony Hey, AHM WS-I+ Grid Interoperability Profile WS-I identifies XSD, WSDL, SOAP, UDDI WS-I+ adds minimum additional capabilities to WS- I to allow development of Grid Services –BPEL and extensions for scientific workflows –WS-Addressing for virtualization of messaging –WS-ReliableMessaging/Reliability to provide basis for fault tolerant and efficient Grid services Expect progress in –WS-ResourceFramework – submitted to OASIS –Notification – dialogue between IT companies –Security – need to understand better relationship of Web Services and Grid approaches –Portlets – generic toolkit for portal construction

19 Enabling Grids for E-sciencE INFSO-RI EGEE and the National Grid Service EGEE Induction, 8 December 2004, NeSC 19 The NGS and GOSC The NGS is the core UK grid, intended for the production use of computational and data grid resources. NGS is the core service resulting from the UK's e-Science programme. NGS is supported by JISC, and is run by the Grid Operations Centre (GOC). The UK Grid Operations Support Centre is a distributed "virtual centre" providing deployment and operations support for the UK e-Science programme. The core of the GOSC is built around operation of the National Grid Service (NGS). The GOSC will support UK services for user authentication, user authorization and project organization, credential management, resource discovery, access portal and more, to be driven by the user requirements.
