In the recent years, the European community of researchers and innovators at work on the next generation Cloud, Edge and IoT computing has been growing in relevance, diversity and impact. For Europe to ensure its technological sovereignty and ground the vision of a computing continuum as the backbone of an open and inclusive society, it is necessary to overcome fragmentation, bring together organisations and individuals from different communities and leverage Open Source.The Concertation and Consultation on Computing Continuum: From Cloud to Edge to IoT meeting is a 2-day physical event organised within the context of the European, Cloud, Edge and IoT Continuum initiative by the OpenContinuum consortium in close collaboration with the UNLOCK-CEI and SW Forum projects and guided by the  European Commission.
