The term “EU sovereignty” carries heavy baggage, yet it dominates discussions about keeping citizen data within Europe. At its core, it means data residency in the EU, but cloud architectures quickly expose loopholes. Deploying to AWS’s eu-west-1 region, for example, still routes authentication, DNS and many services through US‑based endpoints, breaking true residency.

All three big providers promise a European sovereign offering, but none deliver full compliance. AWS lists a “European Sovereign Cloud” as “coming soon,” with limited services and unclear legal standing. Google runs its Frankfurt and Belgium regions under German firm T‑Systems, yet the software stack remains American and subject to US gag orders. Microsoft’s Azure lags further behind, offering no clear sovereign path. The clash between US gag orders and EU notification rules creates a legal gray zone that current frameworks have not resolved.

Practically, the only way to avoid American jurisdiction is to bypass these giants altogether. Smaller EU players like Scaleway or Herzner provide genuine regional services, though they lack the scale of the hyperscalers. Architects must redesign workloads, possibly using tools like Sidero Labs’ Omni for self‑managed Kubernetes, to achieve true data sovereignty without relying on US‑based cloud stacks.
