EURO-3C is a European-funded pilot intended to federate telecommunications, edge and cloud infrastructure across Europe. It could help reduce reliance on non-European providers, but its planned architecture and funding are not proof that Europe has already achieved cloud sovereignty.
What is EURO-3C?
EURO-3C stands for “EUROpean 3C Networks for Secure Telco-Cloud-Edge.” It is a Horizon Europe Research and Innovation Action coordinated by Telefónica Innovación Digital SL. Its stated aim is to build a large-scale, federated, open Pan-European pilot for converged telco-edge-cloud services. The project’s grant agreement is 101297599; the European Commission describes it as a way to develop federated infrastructure and reduce reliance on third-country providers.
In practical terms, “telco-edge-cloud” means bringing telecommunications networks, computing capacity close to users or devices (edge computing), and cloud resources into a coordinated service environment. Federation is central: participating infrastructure providers are meant to work together through common architecture and orchestration, rather than operating as one single cloud company.
Who funds it, and what is the project’s scale?
The European Union funds the project through Horizon Europe. CORDIS lists the total project cost and EU contribution as €74,999,880. The consortium’s published figures describe the intended infrastructure and participating organisations; they should be read as project scope, not as proof that every element is already deployed or operating as a unified commercial service.

How is EURO-3C meant to work?
The project describes six technical pillars for connecting and governing its infrastructure:
- Telco-cloud convergence.
- Multi-level federation.
- Interoperable XaaS services (services delivered “as a service”).
- AI-enabled orchestration.
- Security by design and zero trust.
- Business sustainability.
Its implementation objectives translate those pillars into seven goals:
Rank #2
- Design an open architecture.
- Connect AI-based networking and computing.
- Orchestrate intelligent services and multi-level federation.
- Protect privacy, trust and cybersecurity.
- Deploy pan-European infrastructure.
- Scale business models and market adoption.
- Enable regulatory and policy alignment.
The consortium says it will align with 3GPP, ETSI, GSMA Operator Platform, Sylva, Nephio, Anuket and CAMARA. The purpose is to make services and infrastructure more interoperable across vendors and easier to adopt; naming standards and initiatives as alignment targets does not, by itself, demonstrate that portability has been achieved.
Could EURO-3C make Europe more cloud-sovereign?
It addresses several practical ingredients of sovereignty. A federated platform using European telecommunications and infrastructure providers could broaden where computing runs, support services closer to users, and give European organisations more options than relying on a small set of external providers. The European Commission presents the project in those terms, as an effort to reduce dependence on third-country providers. EURO-3C also states goals of technological autonomy, interoperability and an open, sustainable ecosystem.
Rank #3
But sovereignty is not a single technical feature. A European location for a server does not, by itself, settle which entity controls it, what laws may apply to the provider, who can access data, or whether a customer can move workloads elsewhere. The project’s stated goals around privacy, trust, security and portability are relevant, but its public project descriptions do not establish that all data will be free of non-European legal exposure or that every participating service will offer the same protections.
For a buyer or policymaker, the useful test is to assess the evidence across several dimensions—not to treat the word “sovereign” as a certification:
| Dimension | What EURO-3C sets out to do | What is not established by the cited project material |
|---|---|---|
| Infrastructure control | Federate telco, edge and cloud resources involving European infrastructure providers. | That one European entity controls every layer, provider or operational decision. |
| Data jurisdiction and legal exposure | Address privacy, trust and cybersecurity as project goals. | That every workload is insulated from non-European legal claims or access obligations. |
| Interoperability and portability | Use open architecture and align with named standards and initiatives. | That customers can move any workload between providers without technical or contractual friction. |
| Latency and edge locality | Develop a geographically distributed telco-edge-cloud environment. | Measured latency results for particular locations, workloads or competing services. |
| Security and trust | Make security by design and zero trust technical pillars. | Independent audit results or demonstrated security outcomes across the pilot. |
| Economics and adoption | Include business sustainability and market adoption among its goals. | Prices, commercial availability, or evidence that services will outperform hyperscalers on cost or performance. |
| Production evidence | Plan infrastructure deployment and large-scale use cases. | Proof that Europe has achieved production-scale cloud independence. |
What will the infrastructure be used for?
EURO-3C plans nine large-scale use cases. The published descriptions include automotive, transport, energy, and public protection and disaster relief. These are areas where distributed computing and network integration could matter—for example, applications may need resources close to connected equipment or users—but the project descriptions establish intended areas of work, not delivered services or measured outcomes.

Not yet in the sense of a proven, generally available substitute. EURO-3C is a research and innovation pilot for a federated ecosystem, not evidence of a single finished cloud product with established commercial terms, coverage, performance or workload portability. It may contribute building blocks for European alternatives, but the available project information does not show that it can replace hyperscaler services for a particular customer or application.

When comparing EURO-3C with any cloud or sovereignty offering, check who operates each layer, where data is processed, which laws may apply, how workloads can be moved, what security controls are independently evidenced, and whether the service is commercially available at a sustainable price. Those questions apply to any sovereignty claim, not only this project.
When will EURO-3C deliver results?
The scheduled project period runs through 30 June 2029, according to CORDIS. That gives the initiative time to develop and test its pilot, infrastructure and use cases. It does not guarantee a particular commercial launch date or prove that a pan-European sovereign cloud will exist by the project’s end; those outcomes depend on implementation, interoperability, security, regulation and lasting market adoption.
