Europe is preparing to spend an estimated $23.1 billion on sovereign cloud infrastructure by 2027, according to Gartner forecasts, as governments and enterprises seek greater control over where their data sits and which laws govern it.
The projected spending, expected to triple within two years, reflects growing concern across Europe about digital dependence on foreign-owned infrastructure. Yet industry observers argue that much of the investment may still flow through the same dominant providers that already control the global cloud market.
Amazon Web Services, Microsoft Azure and Google Cloud continue to dominate enterprise infrastructure across Europe, including projects marketed around data sovereignty and local compliance. Critics say that while these arrangements may introduce local hosting or contractual safeguards, they often remain tied to infrastructure governed by US-based companies and subject to legislation such as the US CLOUD Act.
That has prompted a broader debate about what “sovereign cloud” actually means in practice.
Some technologists and infrastructure firms argue that sovereignty cannot be achieved solely through branding, regional data centres or licensing agreements if the underlying governance and operational control remain unchanged. Questions around who selects infrastructure nodes, who controls governance frameworks, and which legal systems apply during cross-border data requests are becoming central to procurement discussions.
The debate comes as organisations across Europe face growing pressure to balance scalability with national and regional data protection requirements. Governments are increasingly seeking infrastructure models that reduce exposure to foreign jurisdiction while still supporting modern cloud workloads.
At the same time, newer decentralised and modular cloud approaches are beginning to attract attention within the sector. Supporters of these systems say they allow organisations to scale infrastructure incrementally, starting with a handful of nodes before expanding capacity without major migrations or software rewrites.
One emerging model described by infrastructure developers involves separating cloud engine functions across multiple node classes, allowing users to independently scale security, query capacity and update workloads. Advocates say this could offer an alternative to conventional hyperscale cloud architecture, though widespread enterprise adoption remains in its early stages.
Analysts note that Europe’s sovereign cloud ambitions are unlikely to be resolved by spending alone. While investment is accelerating, the wider challenge lies in defining how much operational independence organisations truly require, and whether existing infrastructure models can realistically provide it.
