  1. A Glance Towards the Future Mike Mineter Training Outreach and Education University of Edinburgh, UK

  2. Contents • Now • Near future • Not quite so near future

  3. Provisioning Service-Oriented Systems:The Role of Grid Infrastructure Users • Service-oriented Gridinfrastructure • Provision physicalresources to support application workloads • Service-oriented applications • Wrap applications as services • Compose applicationsinto workflows Composition Workflows Invocation ApplnService ApplnService “The Many Faces of IT as Service”, ACM Queue, Foster, Tuecke, 2005

  4. The changing face of research • Moving toward “utility view” – computation and data services provided by a grid • Applications that can be instantiated on chosen grid resources • Effect: people work in their specialisms…. • Researcher does research! • Service providers provide services! • Resource managers manage resources! • EGEE: So 100 years CPU time in a fast response to bird-flu • And… there is a role for application hosting environments e.g. • GEMLCA http://www.cpc.wmin.ac.uk/gemlca/ • AHE http://www.realitygrid.org/AHE

  5. The Application Hosting Environment • Based on the idea of applications as Web Services • Lightweight hosting environment for running unmodified applications on grid resources (NGS, TeraGrid) and on local resources (departmental clusters) • Community model - expert user installs and configures an application and uses the AHE to share it with others • Simple clients with very limited dependencies - can run from the desktop, command line or PDA

  6. AHE: Further Information stefan.zasada@ucl.ac.uk • RealityGrid web site: http://www.realitygrid.org/AHE • NeSCForge: http://forge.nesc.ac.uk/projects/ahe/ • Mailing list: http://www.mailinglists.ucl.ac.uk/mailman/listinfo/ahe-discuss • OMII http://www.omii.ac.uk

  7. Contents • Near future • Not quite so near future

  8. EU initiatives • EGEE is cooperating with many projects…. Most relevant to application developers are: • OMII-Europe http://www.omii-europe.com/ • Amongst goals: Applications can be deployed and run on multiple grid environments through adherence to common services • Not required to develop different solutions for different grids • ETICS – www.eu-etics.orgE-infrastructure for Testing, Integration and Configuration of Software • Mission: Provide a generic service that other projects can use to efficiently and easily build and test their grid and distributed software.Set up the foundations for a certification process to help increasing the quality and interoperability of such software

  9. What will grids be for? New infrastructure for “service-oriented research” • Grids allow research with best models, data, timeliness, ….. • Add service orientation • Take these concepts a step further ?? Grids permit collaborative “virtual computing” Improvised cooperation People with shared goals

  10. Summary • Now • Grids as providers of resources • Roles of researcher, provider more defined • Near future • Application hosting will become a 3rd role • Services supporting the testing of applications • Not quite so near future • Interoperability amongst grids • Not so near as not quite so near future • Service oriented research
