A European consortium is attempting to connect telecoms networks, edge infrastructure, and cloud capacity across national and supplier boundaries, tackling one of the less glamorous but more consequential obstacles to Europe’s digital-sovereignty ambitions: getting different infrastructure to work together.

EURO-3C, a €74.99 million Horizon Europe research and innovation project coordinated by Telefónica Innovación Digital, is developing a federated environment spanning more than 70 production edge and cloud nodes across at least 13 European countries and 15 infrastructure providers.

The programme brings together 87 telecommunications companies, cloud providers, technology suppliers, research organisations, SMEs, AI and security specialists, and industrial users. Rather than building another standalone European cloud, the project is designed to connect existing capacity through common architecture, federation, interoperability, security, and orchestration layers.

Capgemini, which detailed its role in the programme this week, is leading work around architecture, interoperability, data sovereignty, and secure data sharing. The consortium intends to test the resulting infrastructure through nine large-scale use cases spanning automotive systems, transport, energy, industrial applications, and public protection and disaster relief.

Federation tackles a structural European problem

Europe already has substantial telecoms, cloud, edge, and data-centre infrastructure, although much of it sits inside separate operator domains, national markets, and vendor ecosystems. That fragmentation becomes a practical constraint when an application needs low-latency processing in several countries, access to resources from more than one cloud, or consistent security and identity controls across telecom and computing infrastructure.

EURO-3C is designed around a federated model rather than a single provider owning the full stack. Participating infrastructure remains distributed, but shared interfaces and orchestration are intended to allow services and workloads to move across different domains. The technical programme includes telco-cloud convergence, multi-level federation, interoperable services, AI-enabled orchestration, zero-trust security, and work on whether the resulting model can be commercially sustainable.

That is particularly relevant to edge computing, where the commercial proposition has often run ahead of operational simplicity. Processing data closer to a factory, vehicle, power network, transport system, or public-safety operation can reduce latency and avoid moving every workload back to a distant hyperscale data centre, but deploying consistently across many local nodes introduces its own management burden.

A federation layer is intended to make those nodes behave more like a shared pool of infrastructure. An application could, in principle, request computing and connectivity resources without being designed separately around every telecom operator or cloud provider beneath it, while common security and policy controls could reduce the integration work needed whenever another infrastructure domain is added.

Sovereignty depends on interoperability

The programme also reflects a shift in the European debate around digital sovereignty. Complete technological independence is neither practical nor necessarily desirable for most organisations, particularly when semiconductor supply, software ecosystems, and cloud platforms remain internationally interconnected. The more immediate question is whether European businesses and public services can retain meaningful control over data, deployment, supplier choice, and continuity.

Federation offers one route because it can reduce dependence on a single infrastructure provider without requiring every workload to run on a wholly European technology stack. For the model to work, however, portability has to extend beyond contractual language. Identity, networking, data formats, service discovery, monitoring, security policies, and workload orchestration all need to function across participating environments.

EURO-3C is contributing to standards and open-source ecosystems including 3GPP, ETSI, the GSMA Operator Platform, Sylva, Nephio, Anuket, and CAMARA. Alignment with existing standards is important because the commercial value of federation disappears quickly if the result becomes another proprietary layer implemented differently by participating suppliers.

The project is scheduled to run from July 2026 until June 2029, giving the consortium time to move beyond laboratory demonstrations into production-node trials. Its nine use cases should provide the more revealing test, because interoperability is easier to describe at architecture level than to sustain when applications encounter different networks, security policies, performance requirements, and commercial ownership models.

Telecom operators also have a commercial stake in the outcome. Edge computing has long been presented as a way for operators to move beyond connectivity into distributed computing services, although hyperscale clouds have retained much of the enterprise relationship and developer mindshare. A functioning multi-provider federation could give telecom infrastructure a clearer place in application delivery, particularly where low latency, local processing, resilience, or regulated data handling are important.

Europe has no shortage of programmes carrying the language of sovereignty and strategic autonomy, but EURO-3C has a comparatively concrete test ahead of it. More than 70 production nodes are supposed to operate as part of a common environment across providers and borders; whether developers and industrial users can consume that environment without inheriting the complexity underneath will determine how much of the project survives beyond the research programme.
