### Exploring the Future of Service-Oriented Grid Infrastructure: Insights from the University of Edinburgh ###

This document presents a comprehensive overview of the evolving landscape of service-oriented grid infrastructure as discussed in Mike Mineter's training outreach at the University of Edinburgh. It delves into the current state and near-future developments in grid computing, emphasizing how service-oriented applications and workflows can enhance research efficiency. Key roles of researchers, service providers, and resource managers are highlighted alongside applications for hosting environments such as AHE and GEMLCA. The document also discusses upcoming EU initiatives aimed at improving interoperability across grid environments for a seamless research experience. ###

  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
