decision
AWS, Google Cloud or Azure to launch a B2B healthcare SaaS in Europe (GDPR + French health-data hosting, tight budget, due-diligence ready in a year)?
What the panel recorded
Example. A panel compares the three hyperscalers across five criteria and leans to Azure, with AWS as the technical alternative. The models do not fully agree: one asserts that AWS and Google Cloud do not hold French HDS (Hébergement de Données de Santé) certification. A good synthesis flags that claim as contested rather than passing it through.
Primary sources
- Agence du Numérique en Santé — official registry of HDS-certified hosts (esante.gouv.fr)“The ANS registry of certified HDS hosts lists AWS, Microsoft Azure and Google Cloud among 80+ certified providers, alongside OVHcloud, Scaleway, 3DS Outscale, NumSpot and others.”
- AWS — Health Data Hosting (HDS) compliance“AWS holds HDS certification for the Europe (Paris) Region (eu-west-3).”
- Microsoft Learn — Hébergement de données de santé (HDS) France“Azure is HDS-certified for the France Central and France South regions; Google Cloud is HDS-certified for europe-west9 (Paris).”
Verified answer
All three hyperscalers hold French HDS certification (AWS eu-west-3, Azure France Central/South, Google Cloud europe-west9). So the choice is not gated by 'who is certified' — it is a fit question: contracting terms and BAA/DPA maturity, whether the health authority or a hospital buyer expects a specific provider, data-residency wording, and cost. Azure is a defensible default for a French health SaaS on standardised health agreements, but AWS and Google Cloud are equally eligible on the certification point one model got wrong.
Which models were right
The panel's overall Azure lean was reasonable, and the synthesis was right not to trust the 'AWS/GCP are not HDS-certified' claim — the ANS registry contradicts it directly. It is a case of the panel catching one model's factual error instead of averaging it in.
Limits of this case
Certification status and regional coverage change; the ANS registry is the live source. Certification is a floor, not the whole compliance question — contracts, configuration and the specific buyer's requirements still decide it.
