ESA Picks OVHcloud and CGI for Digital EO. The Size Is Not Public.

The European Space Agency has chosen a French cloud provider and an IT consultancy contracting through its French defense and space subsidiary to help build the platform ESA intends to use to federate, process and serve its growing Earth Observation data estate. OVHcloud and CGI France Défense et Spatial announced from Paris on September 28 a 30-month contract to help build Digital EO, which their release calls “the ESA Earth Observation Information System, a strategic, sovereign digital infrastructure designed to federate data, services and processing capabilities related to Earth Observation.”

The number in every headline is 500 petabytes, and it is worth being careful with. It is ESA’s projection of how much Earth Observation data it expects to hold by 2035, not the capacity anyone has bought. HostingJournalist put the warning plainly on the day: “A headline involving hundreds of petabytes should not be mistaken for a purchase order for hundreds of petabytes today.”

What the contract is worth is not public either. The companies describe it as “multi-million-euro” and give no figure, and Reuters reported that ESA did not disclose one.

Key facts

• The deal: a 30-month contract to help build Digital EO, ESA’s Earth Observation Information System, with OVHcloud supplying infrastructure and CGI acting as integrator and architect.
• The footprint: initial deployment in Italy, France and Germany, support operated from Poland, and the stated capability to extend to other European countries and Canada.
• Programs named: Copernicus and DestinE are the two ESA and Commission programs the announcement names as examples of what Digital EO must support.
• The pattern: the award follows another European public-sector selection this year, after OVHcloud joined one of the provider groups chosen under the Commission’s cloud framework in April.

What ESA Bought, and What Nobody Has Said

Digital EO is described in the language of federation rather than consolidation. ESA wants “a decentralized, scalable and resilient digital system” that will “enable the federation with national and European infrastructures.” In practice the platform has to plug into the national ground segments and European facilities that already hold Copernicus data, not replace them, which makes interoperability an operating requirement rather than a feature.

Nicolaus Hanowski, who heads ESA’s EO Mission Management and Ground Segment Department, framed the purpose this way: “With CGI and OVHcloud, we will build and operate a European innovative and sovereign system capable of supporting this ambition and of providing lasting support to the ESA and European Commission programs like Copernicus and DestinE.”

Against that, the list of things nobody has stated is long, and for a hosting audience it is the more useful list:

• The contract value, beyond “multi-million-euro”
• The storage, compute and network capacity OVHcloud is contracted to supply
• How data will be replicated, which workloads run where, and what recovery targets the platform must meet
• Whether any non-European provider bid, and against whom the consortium won

That is not a complaint about secrecy. It is the reason this award cannot yet be read as a revenue event or as evidence of new data center investment. What it does establish is that a European operator can win a multi-year scientific data platform, and that sovereignty is one of the stated design objectives of the system.

Two Tracks, Not One

Digital EO does not stand alone. ESA announced separately that it has signed contracts with ICEYE and Leonardo to lead two European industrial consortia running parallel architecture studies for the EU’s future Earth Observation Governmental Service, a security and defense oriented system for EU governments. Those studies are funded by the European Commission and sit in Element 1 of ESA’s European Resilience from Space program, agreed at the Ministerial Council in November 2025.

So the agency is rebuilding how Europe handles satellite data on two tracks at once: a platform for scientific, public, commercial and citizen uses, which is the one it has just put on a commercial European cloud, and a governmental service whose architecture is still being designed.

Another European Public-Sector Win for OVHcloud

Octave Klaba, OVHcloud’s founder and chief executive, reduced the sovereignty argument to one sentence: “Europe absolutely must have control over the infrastructure that runs its most strategic programs.”

The award follows a pattern rather than breaking one. In April the European Commission awarded its sovereign cloud tender, under which EU institutions, bodies and agencies can buy services for up to EUR 180 million over six years. The Commission split it into four contracts to avoid lock-in on one supplier, and OVHcloud is a partner in one of them, a Luxembourgish-French partnership led by Post Telecom with Clever Cloud.

That group reached SEAL-3 on the Commission’s new sovereignty scale, the digital resilience level, which means its service was judged immune from supply chain disruption by non-EU third parties. Eligibility required SEAL-2.

In February 2025 the company announced with Serco that it would deliver the DestinE Platform for ESA, supplying GPUs and Kubernetes-based services, and said its commitment to data sovereignty would apply European data privacy and security principles to the platform. The new award therefore extends work OVHcloud was already doing inside ESA’s Earth Observation stack. Digital EO is the broader infrastructure, intended to support programs the announcement names as including Copernicus and DestinE.

The financial context is worth stating, and then leaving alone. OVHcloud’s fiscal third quarter, reported in June, showed revenue of EUR 289.6 million, up 6.9 percent like for like, with public cloud at EUR 65.6 million, 22.7 percent of revenue and up 20.2 percent. Without a disclosed contract value, what Digital EO adds to that line cannot be quantified.

For hosting providers in the same market the useful reading is the shape of the deal rather than its size: infrastructure from one European cloud, integration from a consultancy, deployment across three countries with support from a fourth, and a federation requirement that keeps national facilities in the picture. That template may favor operators with infrastructure across several member states over those concentrated in one.

The contract value, the capacity contracted and the identity of any competing bidders are not in the public record. The 500-petabyte figure is ESA’s projection for its total Earth Observation holdings by 2035, as stated in the OVHcloud release, and not a quantity being bought here. Quotations are from that release except where attributed otherwise. Neither ESA, OVHcloud nor CGI was contacted for this article.
