Status of the Grid : Status of the Grid Today: ‘early adoption’ phase - just like the Web in the early days Tomorrow: sophisticated combinations of services to locate information, applications to process it, and computer systems to run them Requirements: Infrastructure to support: e-Science Virtual Organisations e-Commerce e-Utilities


Exposing Resources as Services : Exposing Resources as Services Permissible SLA COMPUTE RESOURCES SERVICE LEVEL AGREEMENT B A C D Defines: What? Who? When? SOFTWARE RESOURCES STORAGE RESOURCES


Open Grid Services Architecture : Open Grid Services Architecture OGSA addresses architectural issues related to broadly interoperable Grid Services. OGSI based on the GSS provides mandatory features, such as service invocation, lifetime management, a service data interface, and security interfaces. GT3 implementation of OGSI & equivalent GT2 services GT3 Jini Jxta GT2 OGSI


UK e-Science Core Programme : UK e-Science Core Programme From Tony Hey’s slides at EPSRC Pilot Project meeting (end of Jan 03) CP I: e-Science Centres & open calls CP II: Plans not promises as dependent on funding SR2002: £16M DTI: £??M


Core Programme 2: Overall Rationale : Core Programme 2: Overall Rationale Assist development of essential, well-engineered, generic, Grid middleware usable by both e-scientists and industry Provide necessary infrastructure support for UK e-Science Research Council projects Collaborate with the international e-Science and Grid communities Work with UK industry to develop industrial-strength Grid middleware


Key Activities : Key Activities UK e-Science Grid/Centres and e-Science Institute Grid Support Centre and Network Monitoring Core Middleware engineering National Data Curation Centre e-Science Exemplars/New Opportunities Outreach and International involvement


The e-Science Grid/Centres and the e-Science Institute : The e-Science Grid/Centres and the e-Science Institute Continuation of e-Science Centre’s & Institute 2 year extension for infrastructure after review Further development of UK e-Science Grid Collaborative Industrial Projects Call for DTI collaborative industrial projects targeted to key middleware areas Grid Support Centre & Network Monitoring


Core Grid Middleware Activity : Core Grid Middleware Activity Need to develop open source, open standard compliant, Grid Middleware stack that will integrate and federate with industrial solutions Software Engineering focus as well as R&D Aim is to produce robust, well-documented, re-usable software that is maintainable and can evolve to embrace emerging Grid Service standards Link UK activities with Europe & US Reduce duplication of effort Standards development & compliance testing


Possible Core Grid Middleware Themes : Possible Core Grid Middleware Themes Heterogeneous Database Integration Security Legal and regulatory Accounting Systems for VOs Collaborative Decision-making Networks Enterprise Computing Systems Outsourcing/e-Utilities Real-time High End Computing Enterprise Application Integration Business Processes for VOs Links to EPSRC CS Research? Autonomic Computing Semantic Grid Rapid Customised Assembly of Services Trusted Ubiquitous Systems ….


ICENI : ICENI The Iceni, under Queen Boudicca, united the tribes of South-East England in a revolt against the occupying Roman forces in AD60. IC e-Science Networked Infrastructure Developed by LeSC Grid Middleware Group Collect and provide relevant Grid meta-data Use to define and develop higher-level services Interaction with other frameworks: Web Services, Jxta etc.


ICENI Architecture : ICENI Architecture RESOURCES POLICY SERVICES USERS


Service Oriented Architecture : Service Oriented Architecture ICENI interfaces for services & discovery Platform neutral interfaces Resource: Abstraction for a capability Policy: How & where the resource is exposed Service: Route for user interaction with a resource Jini Jxta OGSA OGSA ICENI Services Users & Clients Policy Integration & Interoperability Layer Portal


User Interaction : User Interaction API to discover & interact with services Exploit Netbeans Application Framework


Grid Economic Services Architecture(GGF-WG) : Grid Economic Services Architecture (GGF-WG) OGSA Grid Service Service Interface Service Data Service Interface Service Data OGSA Chargeable Grid Service Grid Economic Service Interface Record Resource Usage OGSA Resource Usage Service Contract Negotiation Economic Service Data Contract Verification Service Charging OGSA Grid Banking Service Grid User/Actor
