1. Opening

Rémy

Discussion on /wiki/spaces/WIS2/pages/306970677

Thorsten: it is better to seperate political issues from technical solutions

Remy: 15 GISCs, same cache/Catalogue, not working, in WIS2, we should not go for this path. Shared service among 1 GISCs.

Hassan: WIS2 architecture is on key components/an evolution not revolution, we agreed to reach TT-GISC for the volunteers to run the shared service, not to think aobut the number. To focus on technical issues and then validate them.

Rémy:

Kai: avoid the supercenter that is running all shared services.

Henning: This is a scale-out problem. For modern architecture, it should be designed to be scaled with more flexibility, such as in future there would be more GISCs that can run the shared service.

Rémy: The fact is that not all 15 GISCs are not working properly. The concern is not the GISC center number (15), but to have the center that pretends to work but actually not.

Summary: The team agrees that a shared service is the solution; a small number of centers to run the services; be a scalable architecture design.
