French Sovereign Cloud: Stackit, OVHcloud and the Battle Against AWS and Azure

Stackit, Lidl's cloud, just announced a 1 billion euro investment in Germany. OVHcloud raises 400 million. Scaleway deploys 3 new regions. French sovereign clouds are on the offensive. But against AWS and Azure, which hold 55% of the European market, can they really compete without breakthrough physical infrastructure?

Sovereign cloud is not a marketing concept — it's a regulatory requirement. GDPR requires that European citizens' personal data remain in Europe. The Data Act, which came into force in 2024, reinforces this constraint by imposing data portability and service interoperability. For a company processing health, finance, or defense data, sovereign cloud is not an option — it's an obligation.

But obligation doesn't automatically create the market. French sovereign clouds (OVHcloud, Scaleway, STACKIT, Outscale) together represent 8% of the European cloud market. AWS alone holds 32%. Azure, 23%. The difference is not in the software — it's in the infrastructure. An American hyperscaler has 200+ regions worldwide. OVHcloud has 37. Scaleway, 8.

Stackit: The German Surprise That Shakes the French

Stackit is Lidl's cloud, the German distributor. Launched in 2020, it went from zero to 1 billion euros in revenue in 6 years. Its model is simple: host Lidl's workloads, then sell excess capacity to third parties. It's the same model as AWS (Amazon Web Services, born from Amazon's need), but with a European twist: sovereignty guaranteed by German law.

Stackit's success rests on a fact that French clouds underestimated: SME trust. A German SME prefers to host its data at Stackit — because it's German, because it's reliable, because support is in German. The same logic applies in France: French SMEs prefer OVHcloud or Scaleway. But the problem is capacity. OVHcloud doesn't have enough datacenters to absorb demand if all French SMEs migrated tomorrow.

OVHcloud: The French Champion with Feet of Clay

OVHcloud is the largest European sovereign cloud. 37 datacenters, 1.6 million customers, 900 million euros in revenue. But its history is also a warning. In 2021, the fire at its Strasbourg datacenter destroyed 3.6 million websites and caused a loss of 60 million euros. The incident revealed a structural fragility: the overconcentration of workloads in a single site.

Since then, OVHcloud has invested in geographic redundancy. But the lesson remains: a sovereign cloud is not sovereign if it is not resilient. And resilience is not bought in software — it is bought in datacenters. OVHcloud must build 10 new datacenters by 2030 to keep its sovereignty promise. This represents 2 billion euros in investment. Where to find this money? The answer is in the financial markets — and this is where institutional investors come into play.

The Investment Thesis: Datacenter as Cornerstone

The battle for sovereign cloud will not be won in user interfaces or prices. It will be won in the ability to offer certified, decarbonized, and resilient physical infrastructure. This is precisely what FINXIA Capital's TITAN DC AI strategy aims to do: transform existing brown datacenters into certified green infrastructures, ready to host sovereign cloud workloads.

FINXIA Capital has identified 23 assets in France that, once transformed, could become anchor sites for OVHcloud, Scaleway or regional sovereign clouds. These assets are located in areas where demand is strong but supply is low: Lyon, Marseille, Toulouse, Nantes, Lille. A 10 MW datacenter in these cities, Tier III certified and PUE < 1.20, can generate a return of 10% to 12% — well above the primary market.

What Investors Must Understand

French sovereign cloud is not a fad. It is a structural trend supported by regulation, geopolitics, and citizen awareness. The French no longer want their data hosted in Virginia or Oregon. They want it to stay in France. This demand, multiplied by 27 million European SMEs, creates a market of 15 billion euros by 2030.

The investor who understands this dynamic does not bet on a single cloud — they bet on the infrastructure that makes them all run. Datacenters. Real assets. Bricks and mortar. This is where value is created. This is where sovereignty is built. And this is where FINXIA Capital invests.
