France Grilles is a research infrastructure and a GIS created in 2010 to coordinate and steer the French computing grid, in conjunction with the EGI federated infrastructures. Based on a federation of regional and national computing sites, it has enabled several of them to be involved in European projects linked to the construction of the EOSC. This presentation will detail the feedback from the SCIGNE platform, a regional-scale infrastructure based in Strasbourg and providing services for several French and European projects. This feedback will address both the positive points of integration into EOSC and associated projects, as well as the points that still need to be improved.
