From December 1 to 4, 2025, Nantes hosted the 18th edition of the IEEE/ACM UCC international conference, a must-attend event for experts in cloud and utility computing. This year, the event highlighted flagship projects from the PEPR Cloud, with French researchers taking center stage.
The UCC 2025 conference, held at Halle 6 Ouest at the University of Nantes, brought together researchers and industry representatives to explore advances in cloud and edge computing and their applications. Among the key moments, Anne-Cécile Orgerie (CNRS/IRISA), an expert in the carbon footprint of distributed systems, delivered a keynote on carbon accounting allocation models as part of the CARECloud project, supported by the PEPR Cloud. This national program, dedicated to innovation in sovereign and sustainable cloud technologies, thus takes the spotlight.
The event was co-led by major figures in the field: Daniel Balouek, conference organizer, and Hélène Coullon, program committee chair (both members of the TARANIS project). Their involvement reflects the dynamism of French research, particularly within the PEPR Cloud, which funds projects aimed at more efficient and environmentally responsible digital technologies.
With themes such as reducing environmental impact and optimizing infrastructures, UCC 2025 confirmed Nantes as a center of excellence where science and innovation converge to shape the cloud of tomorrow.
