Microsoft has announced a major Microsoft private cloud expansion to strengthen its Sovereign Cloud capabilities across public and private environments. The update addresses growing global, and particularly European, demands for data residency, operational control and digital sovereignty. As regulatory expectations increase, Microsoft aims to provide cloud options that ensure transparency, regional processing, and customer control.
The announcement reflects a broader industry push. Google recently expanded its sovereign cloud portfolio with an air-gapped solution, while AWS formed a dedicated EU-based cloud unit to meet similar requirements.
Svetlana Geiger, Trusted Advisor at Microsoft, noted on LinkedIn that organizations “need the cloud’s power without losing control of their data.”
Microsoft Private Cloud Expansion and the EU Data Boundary
The strengthened EU Data Boundary remains central to the Microsoft private cloud expansion. Microsoft guarantees that data processed by AI services for EU customers will stay within the European Union unless users explicitly choose otherwise.
The company is also expanding in-country processing for Microsoft 365 Copilot interactions. By the end of 2026, processing will be available in 15 countries, beginning with Australia, India, Japan and the United Kingdom in 2025.
New Sovereign Landing Zone Supporting Microsoft Private Cloud Expansion

- a prescriptive compliance architecture
- a revised Management Group hierarchy
- updated Azure Policy definitions
- guidance for deploying controls such as Azure Key Vault Managed HSM
These updates simplify compliance for customers with strict regulatory obligations.
