  1. Enabling application technologies Architecture, Design and Development of the next generation Grid European Grid Technology Days 2005 IST-FP6 Grid projects concertation June 1-2, Brussels Wolfgang Boch DG Information Society Grid Technologies http://www.cordis.lu/ist/grids/

  2. Objectives of collaboration activities • Increase effectiveness of EU collaboration beyond individual consortia • Speak with a single European voice • Increase impact in common activities that require critical mass of this event • Discuss achievements of the first period • Agree on future activities and possible adjustments of strategy, also in the light of evolving trends

  3. Service Oriented Architectures:Adding flexibility to business IT • A Service-Oriented Architecture (SOA) is an architectural concept • Most popular implementation through web services (SOAP, WSDL, UDDI) • Standardized use of services to meet the requirements of business applications • Highly-interoperable over different implementations (e.g. Java and .NET), including legacy solutions • Re-usability of software components, transforming monolithic applications into services • Loosely coupled services  Business agility!

  4. Service Oriented Architectures:Complementing and exploiting the added value of Grids “…while SOAs may be the conceptual framework for increased agility on the application layer, the actual execution of modularized services requires a much better command of enterprise resources than the typical organization has today. SOA can use common Web services protocols (XML, SOAP, WSDL and UDDI) to distribute processes, but it in and of itself doesn't describe the distribution and management of the resources.” Ian Foster (Computerworld, 29 Nov. 2004) Technology convergence or separation of concerns? SOAs Grids • Resources shielded by Services • Re-use of business IT components • Loose-coupling • Standards • … • Making business IT & processes Agile • Virtualisation of resources • Resilience • Persistent data • Security • Self-management • Load balancing • … •  Reducing TCO

  5. SEASIDE: service integration through SOAs • SOAs bear the promise of a new wave to achieving full modularity of complex software and services systems • To provide support for configuration (model-driven development) • composition/grouping of functional/business modules to generate new functionalities or business modules; • enabling IT business systems to evolve and extend without manual programming/integration • To provide support for dynamic (runtime) reconfiguration • Modifying software without stopping execution/processes, – thus meeting the demands for continuous evolution of complex business processes • Dynamic revision through semantically equivalent, dynamically-bound services • Self-adaptation to reflect the culture of a client user.

  6. Is Service-Oriented Architectures on the critical path in the move of Grids from e-Science to Business ?

  7. This session agenda This year concertation will start with a debate on Service-Oriented Architectures • OGSA vision for Service-Oriented ArchitecturesDave Berry, NESC • Service-oriented Architectures: Potential and ChallengesAlexander Schill, Univ. of Dresden • The use of SOA and GRID technology to allow telcos to act as efficient IP service providers in the futureErik Dahl, Telenor Networks • The Enterprise Grid Alliance Reference Model Dave Pearson, Enterprise Grid Alliance
