  1. The Next Generation Grid Kostas Tserpes, NTUA Beijing, 22 of June 2005

  2. NextGRID Project • Integrated Project • Grid Based Systems for Complex Problem Solving • Project Start Date: 1 September 2004 • Duration: 36 months

  3. Outline • Vision • Goals & Objectives of NextGRID • Consortium • Process • Specific Areas addressed by NextGRID • Topics of Potential Interest

  4. NextGRID Vision An architecture for Next Generation Grids which will enable its widespread use by research, industry and the ordinary citizen thus creating a dynamic market place for new services and products.

  5. NextGRID Goals • Develop architectural components that will lead to the emergence of the Next Generation Grid. • Prepare the way for the broader use of Grid technologies and their widespread adoption by organisations and individuals from the business and public domains. • Improve the technology in key areas such as security, development of applications, interoperability, quality of service and robustness. • Contribute to the standards which are essential if Next Generation Grids are to succeed.

  6. NextGRID Partners Academic partners

  7. NextGRID Partners Commercial partners

  8. The NextGRID Process • Applicationneeds • Existing BusinessModels • Existing standards • Expertise • Experience withGrid in production Conceptualisation Analysis Design • Architecture • Grid Business Models • Reference Implementations • Applications • Standards Feedback for next iteration Implementation Evaluation

  9. Areas which NextGRID is addressing • Architecture • Business and Operational Issues • Foundations and Core Services • Dynamics • Interactions • Applications

  10. NextGRID Architecture Goals • Advanced Service Oriented Architecture • Component Based • Use Existing Technology where Possible • Open and Fully Accessible Specifications • Multi purpose Grid • Guaranteed Minimal Grid Infrastructure
