UNLOCK CEI’s ambition is to UNLOCK the potential for accelerating the deployment of the Cloud-to-Edge-IoT (CEI) computing continuum in Europe by focusing on the demand-side drivers and challenges to identify technology-driven innovation and business opportunities driving demand value chains. The project represents the CEI demand constituency; provide insights and guidance to the Horizon Europe R&D projects in this domain; and contribute to a proactive dialogue with the supply stakeholders to encourage the development of an open European CEI ecosystem. It focuses on emerging value chains where investment is needed to foster the deployment of the Cloud-to-Edge-IoT continuum through the forthcoming CEI large scale pilots. This will ultimately foster European autonomy in the digital economy. The workplan is designed to provide early results to feed into the development of the HE Work Programme in 2023-24 based on the ongoing dialogue with the stakeholder ecosystem. The project pays specific attention to data governance issues, leveraging the relationship with industry-driven initiatives such as Gaia-X and CCAM (Connected, Co-operative & Automated Mobility) partnership. UNLOCK carries out a systematic assessment of the state of the open European CEI ecosystem and develop future market scenarios and related market pathways for the development of the open European CEI ecosystem. It will engage with industry stakeholders representing the most relevant industry value chains in Europe for CEI potential demand and develops a productive and effective interface between the demand constituency and the supply side, including the coordination of HE projects resulting from CL4-2021-DATA-01-05, CL4-2022-DATA-01-02, and CL4-2022-DATA-01-03 and Cluster 3 cybersecurity projects. It finally designs and implement a coordinated communication and dissemination strategy running throughout the lifetime of the project to create awareness about the whole of the European demand-side landscape.
