The location is east of the Hellas basin at 41° South and 101° East. The area is 100 km across, with a resolution of 12 m per pixel, and shows a channel (Reull Vallis) once formed by flowing water. The landscape is seen in a vertical view, North is at the top.

©STFC/Keith G JefferyThe Future of GRIDs: A European Perspective Background Rationale –Recognises the current view of the end-point (SOKU) –Recognises the current state-of-the-art –Takes into account the outputs from previous Challengers workshops –Takes into account what is happening in the world in the ICT area specifically in e-infrastructure, GRIDs, SOA etc –(with acknowledgement to NGG, EC-Funded GRIDs projects, NESSI, 3S and others)

©STFC/Keith G JefferyThe Future of GRIDs: A European Perspective SOKU Revisited The key point is that SOKUs are self- standing, self-managing services that can self-compose and/or be composed This implies they either: –Cooperate with some composer (orchestrator, choreographer) via an interface discovery, composition, execution, monitoring, recomposition or –Manage themselves dependent on parameters via an interface (and their own intelligence) –Cooperate with others via parameters passed through an interface (shared intelligence) –In both composition and execution phases

©STFC/Keith G JefferyThe Future of GRIDs: A European Perspective Note The SOKU (services) can be wrapping: –Fully composed services end-to-end from user to e-infrastructure (servers, data stores, communications) –Data or information (or knowledge) sources –Software sources –Physical hardware resources (servers, communications, detectors, user devices) –Persons -in roles- (agents) –…….

©STFC/Keith G JefferyThe Future of GRIDs: A European Perspective SOKU key point Interfaces defined by metadata: –Schema (to assure correctness e.g. database schema or formal functional signature) –Navigational (to reach it e.g. URL) –Associative (to use it) Descriptive (what the service can do including any functional limitations e.g. precision, accuracy) Restrictive (conditions to use the service like cost, rights (trust, privacy, security), performance parameters,… –And supported by Supportive (domain-level (not service-level) metadata such as thesauri, domain ontologies… The metadata is used at composition and execution time The metadata provides the flexibility for self-* The metadata allows intercommunication through the software stack so that service levels for NFRs can be realised This may involve dynamic recomposition (i.e. self-*)

©STFC/Keith G JefferyThe Future of GRIDs: A European Perspective And behind it all….CS issues Mobile code –Be able to move the code to the data rather than data to the code –Share code among nodes active in one request (distribution / parallelism) Performance and optimisation –Over computation, network, data source Synchronisation, consistency, reliability –For mobile devices (PDAs, detectors, instruments…) –In a dynamic environment Conclusions

©STFC/Keith G JefferyThe Future of GRIDs: A European Perspective What does this mean for ISE? Both Data modelling and System Implementation Representation of real world –Connected graphs not only hierarchies (to represent real world) hierarchies represent a limitation of the human view of complex structures –Complex semantics (systems need to understand for autonomy) Domain ontologies to provide supportive metadata for interoperability well-formed richly-structured syntax to permit tractable programming –Business processes (because they evolve) general code and execute-time binding of data Configured dynamically by representative metadata Global state –Local state and active interfaces between local stateful systems Conclusions

©STFC/Keith G JefferyThe Future of GRIDs: A European Perspective What does this mean for ISE? Transactions (represent real world, not idealised CS world) –Complex, multi-level, local but with open-ended properties E.g. Orders, invoices… –Messaging interfaces Completeness –Dealing with incomplete information for decision-making –Probability, fuzziness, learning systems Certainty –Dealing with uncertain information –Probability, fuzziness, learning systems Optimisation –No global state so local, maybe wider with negotiation –Partitioning, approximation, much use of metadata Conclusions

©STFC/Keith G JefferyThe Future of GRIDs: A European Perspective What does this mean for ISE? Trust –Representation of business organisations, their policies (how?) –Contracts and proposals (some progress) –Servicel level agreements (some progress) Security –System availability and continuity under attack –Prevention of unauthorised system access –Authentication and authorisation – global or connected local systems Privacy –Openness of personal data to data subject (right to correctness) –Security of personal data to others (right to privacy) Unacceptable Use –What does a spam transaction look like? –Hijacking of system by adult, political, racist…. transactions Conclusions

©STFC/Keith G JefferyThe Future of GRIDs: A European Perspective Conclusions The UK e-Science programme led the way NGG1,2,3… provides a courageous vision With many challenging R&D topics aims to provide the architecture of the ICT environment of the future for business and science, for healthcare and environment, for culture and leisure Challengers provides the roadmap to 2025
