Sustainability: Ideas in the Beginning
 Learn from others, collaborate with others
 Sustainability in architecture (standards), technology (robust),
users (applications), market, legal, government,…
 Start with a plan for sustainability before you start with a plan for the grid
 Users and applications are main drivers of sustainability
 Develop clear benefits for users
 Make everything easy to use
 Political and policy landscape has to be right

Challenges for Research and Industry
•
•
•
•
•
•
•
•
•
•
•
•
Sensitive data, sensitive applications (medical patient records)
Different organizations get different benefits
Accounting, who pays for what (sharing!)
Security policies: consistent and enforced across the grid !
Lack of standards prevent interoperability of components
Current IT culture is not predisposed to sharing resources
Not all applications are grid-ready or grid-enabled
Open source is not equal open source (read the small print)
SLAs based on open source (liability?)
“Static” licensing model don’t embrace grid
Protection of intellectual property
Legal issues (e.g. FDA, HIPAA, multi-country grids)

Lessons Learned and Recommendations
– Continuity: Grid infrastructure should be modified and improved in large cycles
only: applications depend on infrastructure !
– Sustainability: Funding should be available after end of project, to guarantee
services, support and continuous improvement.
– Interoperability: Use open-source software and standards especially in the
infrastructure and application middleware layer.
– Collaboration: between infrastructure developers and the applications, to best
utilize grid services and to avoid application silos.
– User-Friendliness: for easy adoption for new communities. Infrastructure group
should offer installation, operation and support services.
– Grid Services: Centers of Excellence should specialize on specific services,
e.g. integration of new communities, grid operation, utility services, training,
support, etc.
– Participation of Industry: has to be industry-driven. Push from outside, even
with govmnt funding, is not promising. Success comes only from real needs
e.g. through already existing collaborations between research and industry.

D-Grid: Towards a Sustainable
Infrastructure for Science and Industry
 Govt is looking into changing policies for resource acquisition (HBFG ! )
to enable a service model
 2nd Call: Focus on Service Provisioning for Sciences & Industry
 Strong collaboration with: Globus Project, EGEE, Deisa,
CrossGrid, CoreGrid, GridCoord, GRIP, UniGrids, NextGrid, …
 Application and user-driven, not infrastructure-driven
 Focus on implementation and production, not grid research, in a
multi-technology environment (Globus, Unicore, gLite, etc)
 D-Grid is the Core of the German e-Science Initiative

Results of the Workshop
Requirements
 There is a general need for a sustainable infrastructure
 Funding agency demands cost-neutral operation
 Securing long-term investments and ROI
 But: not only monetary considerations: enables long-term research
collaboration and competitive research infrastructure
 Benefits for all constituencies
 Access to resources AND long-term data preservation
 International integration
 Acceptance of infrastructure through ease of use
 Long-term planning important for attracting new communities
 Include learning (GridKa), testing, support, and production

Results of the Workshop
Challenges
 Heterogeneous middleware complicates building sustainable grid,
but necessary for international collaboration => sustainability
 Today: grids are complex and user unfriendly environments
 Integrating new hardware from new partners & communities; How ?
 Currently, D-Grid is not a ‘legal’ entity, problem for contractual collab
 Long-term financing of resources and their usage/operation unclear
 Grid-enabled software licensing models still missing
 Broadening community grids beyond their current core members
 Germany: “Laender” investments restricted to ‘regional’ usage

Results of the Workshop
Steps towards a sustainable infrastructure
 Significantly increase number of grid users, far beyond early adopters
 Govt funding for resources dedicated to D-Grid was key
 Support of several middlewares important
 Long-term goal: independence of D-Grid from funding …
 … but mid-term funding: prototype  production
 Encourage Govt to change current funding policies for resources
 Professional user support of utmost importance (DGI & CGs)
 Excellent support  excellent people  long-term contracts
 Industry participation as users (SMEs) and providers (IT companies)

Results of the Workshop
Conclusions and Recommendations
 D-Grid seems to be on track towards a sustainable infrastructure
 A centralized resource infrastructure is important, but the how
still has to be discussed (DGI vs CGs)
 Implementation of sustainable D-Grid only together with users (CGs)
 Sustainable usage (business) models only with users (CGs)
 Integration of D-Grid in European infrastructure is important
 Central D-Grid institution should encourage broad acceptance
of D-Grid, incl certification of and support for resources
 Role of industry unclear, but participation possible today
