GetSovereignAWS vs Azure Sovereign Cloud: Residency & Control Compared
Both AWS and Azure are US-owned hyperscalers with sovereign programmes. The comparison below separates what is genuinely different (sovereign architecture, government footprint, AI posture) from what is equivalent (ownership jurisdiction, residency mechanics, key control).
| Dimension | AWS | Microsoft Azure |
|---|---|---|
| Ownership jurisdiction | 🇺🇸 United States (Amazon.com) | 🇺🇸 United States (Microsoft) |
| Local regions (launch set) | Sydney, Mumbai, London, Paris + EU Sovereign Cloud (DE) | Sydney/Melbourne, Pune, London, Paris + Sovereign Landscapes (DE) |
| Data residency | In-region; EU Sovereign Cloud has independent data residency | In-region; Sovereign Landscapes isolate country footprint |
| Operational sovereignty | Provider-operated; EU Sovereign Cloud independently operated in EU | Provider-operated; Sovereign Landscapes operated in-country |
| Customer-controlled keys | Yes — KMS, CloudHSM, external key stores | Yes — Key Vault, Dedicated HSM, key-residency policies |
| Local personnel | In-region support available; restricted access options | In-region support available; Sovereign Landscapes restrict access |
| Government offering | GovCloud (US), Dedicated Regions, Air Gap; IRAP/FedRAMP/C5 | Azure Government, Sovereign Landscapes; IRAP/FedRAMP/C5 |
| Sovereign product name | AWS European Sovereign Cloud | Microsoft Cloud for Sovereignty / Sovereign Landscapes |
| AI infrastructure | Bedrock in-region; p5/p6 GPU instances | Azure OpenAI in-region; ND-series GPUs |
| AI training on customer data | No by default | No by default |

The verdict
For most buyers, AWS and Azure are equivalent on sovereignty fundamentals. Both are US-parented, both keep data in-region, both offer customer-managed keys, and both now offer EU/national sovereign programmes. The differences that matter: Azure's Sovereign Landscapes are operational in more countries with a policy-enforcement layer (Cloud for Sovereignty), while AWS's EU Sovereign Cloud goes furthest on independent EU operation. Choose on ecosystem, price and specific in-country sovereign availability — not on a generalised "more sovereign" label.
Where ownership is decisive. If the parent jurisdiction itself is the constraint, neither qualifies — compare OVHcloud, Open Telekom Cloud or AUCloud instead.
