All roads lead to better science
Europe has been making significant strides in improving how it approaches scientific advancements, how fast it innovates and deploys the new discoveries. Two processes that started on separate tracks, now seem to be converging to the same path.
The first is the re-procurement of the EOSC EU Node, the managed-services contract that has run the core of the European Open Science Cloud since October 2024. The Commission has already confirmed the re-procurement is underway, built into the Horizon Europe Research Infrastructures Work Programme 2026-2027 as a four-year framework contract.
On the other hand, Tech Sovereignty Package has been rolled out on 3 June 2026, aimed at semiconductors, colud, AI and open source at the scale of the whole European economy. It isn't aimed directly at EOSC. However, it lands the middle of the EOSC re-procurement planning window, and it sets out criteria and funding instruments that any organisation bidding into EU-funded digital infrastructure in the next few years will need to read carefully, EUDAT included.
What's actually changing in the re-procurement
The current EOSC EU Node deal was a 36-month build-and-operate contract split into three lots. The 2026 procurement is described by the Commission as a four-year framework within which it can call off managed services and development work as needed, rather than a fixed scope delivered once. In this way, EOSC will grow into a single unified and continuous entity.
Prolonged funding also means the EOSC EU Node has grown into something with real usage to protect. The winners of the procurement will have to service and support more than 5,500 registered users, with the signficance of the smooth continuity of service being one of the key requirements for the European Commission.
The Node is no longer operating in isolation. Fourteen new candidate EOSC Nodes were endorsed in April 2026 at the Tripartite Event in Cyprus, on top of the first wave of 13 that included EUDAT itself. The EU Node's role is shifting from “the EOSC platform” toward “the reference node inside a growing federation,” with early federation onboarding, interfederated AAI, and connections to the EuroHPC Federation Platform all part of the roadmap. Any bid now has to speak to interoperability with a real federation, not a single centralised service.
Why does the Tech Sovreignty Package matter
Although the EOSC EU Node will not be funded under the revisions provided by the Tech Sovreignty Package, what is important is the signalling and the agenda Tech Sovereignty Package sets for all the initiatives working in research and innovation field.
- The “Union added value” criteria being written into CADA for cloud and AI procurement are the kind of language that tends to migrate into adjacent EU tenders over time, including research-infrastructure ones, once they become the norm for public procurement generally. An EOSC re-procurement launched in late 2026, after CADA's first reading, is more likely to echo this vocabulary than one launched a year earlier would have been — even without a legal requirement to do so.
- The Open Source Maintenance Instrument is a live funding line that a research-data infrastructure with an established, EU-governed open-source service suite could plausibly draw on to sustain services between Horizon Europe project cycles — a genuine complement to procurement income rather than a substitute for it, but one worth having a position on.
- The EuroCloud Federation's pooling logic is close in spirit to what EOSC has been trying to do for national and thematic nodes since the build-up phase started. A bid that can show it already operates in that pooled, federated mode has a story that fits the broader policy direction, even though EuroCloud Federation and the EOSC Federation are formally separate initiatives.
How EUDAT should position its bid
The new strategy that has emerged also signals to EUDAT on how to position itself in the upcoming bid.
Firstly, the establishment of a governance team matters just as much as a comprehensive infrastructure. EUDAT's B2 services suite (B2DROP, B2SHARE, B2FIND, B2HANDLE, B2SAFE, B2ACCESS) is already operated by European research and e-infrastructure organisations, under EU-based governance, with data staying on infrastructure controlled by EUDAT members. That maps closely onto the control-over-service and control-over-supply-chain criteria CADA is putting at the centre of its sovereignty tiers. It's a stronger differentiator against globally-scaled commercial cloud providers than a technical feature comparison would be, and it's worth stating explicitly rather than assuming evaluators will infer it
Another important component should be refering to the impact on European sovereignty. Nothing in the current re-procurement documentation requires CADA-style sovereignty assessments. But given the timing, it would be a mistake to assume the evaluation criteria won't be influenced by the same logic. Framing EUDAT's existing services against CADA's four assurance levels now, even informally, gives the bid a ready answer if the tender text asks for it.
Next steps
The re-procurement timeline and the Tech Sovereignty Package won't wait for anyone to finish reading about them, which is exactly why the positioning work described above needs to start now. For organisations trying to work out where their own infrastructure, services, or national node plans fit within this shifting sovereignty landscape, EUDAT has already mapped a good part of this terrain through its own Node journey. The Landscape section of the EUDAT website is a good starting point for that conversation.
