The 6G telco cloud is poised to become a hybrid multi-technology environment, with communication, computing and acceleration resources increasingly being offered by hyperscalers and multi-MNO Federations, aiming to support the deployment of future-looking Digital Services. In order to succeed, the future 6G Telco Cloud is expected to converge Information Technology (IT) and Networking Technology (NT) platforms under a unified continuum of resources, while introducing full automation for managing their lifecycle. In order to make this vision a reality, SOVEREIGN-6G delivers the first 6G Telco Cloud in Europe, which will serve as the foundation of future-looking Digital Services aggregated and exposed by a groundbreaking Unified Service Platform. To this end, an evolable experimentation infrastructure is delivered, that integrates 6G sites from all over Europe and serves as a playground to test 6G breakthrough technologies for the future telco cloud. A Digital Service Orchestrator is also delivered, to provide SLA assurance over a dynamic compositioning of heterogeneous resources (e.g., compute, network, GPU) in this hybrid, multi-technology Telco Cloud Continuum environment. SOVEREIGN-6G is structured around 3 pillars: Pillar 1 is Delivering a new Unified Service Platform, as a Digital Service Aggregator envisioned to operate in increasingly complex ecosystems involving multiple stakeholders; Pillar 2 involves integrating IT, OT and NT platforms in an telco cloud continuum, alongside breakthrough 6G enablers; and Pillar 3 delivers a Native AI edge, addressing distributed inference, sovereign Edge AI workloads acceleration, and physical awareness via multi-modal sensing. Together these 3 Pillars that help address the main challenges that will mark the successful transformation of CSPs to DSPs.
