2. Information Society and Media Directorate-General - Unit Grid Technologies Concertation Meeting – 1 st June 2005 Slide 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. Information Society and Media Directorate-General - Unit Grid Technologies Concertation Meeting – 1 st June 2005 Slide 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. Information Society and Media Directorate-General - Unit Grid Technologies Concertation Meeting – 1 st June 2005 Slide 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) Grids SOAs Virtualisation of resources Resilience Persistent data Security Self-management Load balancing …  Reducing TCO Technology convergence or separation of concerns? Resources shielded by Services Re-use of business IT components Loose-coupling Standards …  Making business IT & processes Agile

5. Information Society and Media Directorate-General - Unit Grid Technologies Concertation Meeting – 1 st June 2005 Slide 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)  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.
