Sovereign cloud: where to host your data?

Why and where to host your enterprise data in sovereign cloud. OVHcloud, Scaleway, S3NS: comparison and selection criteria. What is a sovereign cloud? It is a hosting service designed to keep your data stored and processed inside a defined legal jurisdiction such as France or the EU, under providers subject to local law. That matters because the GDPR, sector rules and contractual commitments all depend on where data lives and who can access it. Why it matters in practice: sovereignty is not just a compliance topic. It is also about control, reversibility and the ability to explain your architecture to clients, auditors and partners. French and European options such as OVHcloud, Scaleway and Outscale provide credible alternatives for infrastructure, while providers like Clever Cloud or Infomaniak can fit simpler web workloads. A safe migration starts with an inventory of hosted services and data flows, then checks portability, containerisation readiness and rollback options. At Powehi, we recommend phased migration with parallel testing, especially when the workload is critical. Sovereign hosting does not mean slower systems; it means more predictable legal and operational control.
