2. 2 Enterprise Requirements (or What I’ve Learned from EGA) Mission critical applications –Reliability is very important Performance requirements –Best effort is not sufficient for some processing scenarios Must be compatible with existing (legacy) infrastructure –Can’t just throw-away current infrastructure and start over Commercial and technical workload –Transactional processing –Batch processing –Databases and Data Archives –Compute and Communication Intensive Key Enterprise Grid Technologies (for all grid applications, actually) –Abstraction –Virtualization –Automation Use Cases (processing scenarios) drive system design

3. 3 Further Observations Practical deployment –Simplified system to ease design and deployment –Get something simple up and running quickly –Design choices "hardcoded" Fundamental Trade-off between Flexibility/Capabilities and Simplicity/Performance –Grids are about sharing resources –Grids are about hardcoding as few design decisions as possible Virtualization –Dynamic service provisioning –Dynamic data provisioning End-to-end system management A Posteriori Computing

4. 4 IVO and GGF-18 GGF-18: Sept 11-14, 2006, Washington, D.C. Connections between IVO and Earth Observation communities –CEOS –GEOSS –IPY Extensive overlap in type of work and grid requirements Get visibility and make arguments to funding agencies, governmental agencies (all regions! US, EMEA, AP), international organizations
