67. Summary and conclusions
The EGEE middleware:
Is exiting prototyping phase and entering real production phase (LHC first real data are only 2 years away from now!)
Implements a full and complete stack of grid services that can be used all together or separately at user’s discretion
Closely follow the standardization process going in GGF and other for a
GILDA is a real virtual laboratory for dissemination of grid computing:
It is a “de facto” standard t-Infrastructure adopted both by EGEE and some forthcoming EU-FP6 projects (EELA, EUCHINAGRID, EUMEDGRID, ICEAGE)
It is a complete suite of grid elements (test-bed, CA, VO, monitoring system, web portal, live user interface, user interface plug&play) and applications fully dedicated to dissemination purposes and pre-porting of new applications to EGEE Infrastructure
GILDA runs latest production (stable) version of both the LCG grid middleware but it is also early adopting gLite in order to make the transition to the new middleware smoother and easier
