Overview

Microsoft recognizes that organizations have diverse sovereignty requirements based on their industry, regulatory obligations, and operational needs. To address this spectrum of requirements, Microsoft offers three distinct sovereign cloud models that provide varying levels of control, isolation, and compliance capabilities.

These models enable organizations to:

Balance sovereignty needs with cloud benefits: Maintain control while leveraging cloud innovation
Meet regulatory requirements: Comply with local laws and industry-specific regulations
Optimize for specific use cases: Choose the right model based on workload characteristics
Scale as needs evolve: Transition between models as requirements change

Why Multiple Models Matter

Different organizations have different sovereignty needs:

A European bank may need data residency guarantees but can operate in a shared infrastructure
A defense contractor requires physical isolation and no external connectivity
A government agency needs infrastructure operated by local entities with regional compliance certifications

No single solution fits all scenarios. Microsoft’s three-model approach provides flexibility while maintaining high security and compliance standards.

Common Pitfalls

❌ Choosing the Wrong Model

Pitfall: Selecting model based on perception rather than requirements

Example: Choosing Sovereign Private Cloud because “it sounds more secure” when Sovereign Public Cloud meets requirements at lower cost

How to Avoid:

Complete thorough requirements assessment
Use decision framework systematically
Consider total cost of ownership
Prototype/POC before full commitment

❌ Underestimating Operational Complexity

Pitfall: Assuming on-premises Azure Local is “as easy as cloud”

Example: Deploying Azure Local without trained staff or operational procedures

How to Avoid:

Invest in training for operations team
Start with Connected mode before Disconnected
Document operational runbooks
Plan for ongoing maintenance and support

❌ Ignoring Network Requirements

Pitfall: Not planning for bandwidth, latency, and connectivity needs

Example: Deploying Azure Local in Connected mode without sufficient internet bandwidth

How to Avoid:

Assess network requirements for chosen model
Plan for ExpressRoute if needed
Consider bandwidth for updates, backups, and monitoring
Test connectivity and latency before go-live

❌ Over-Complicating with Multiple Models

Pitfall: Using all three models when one would suffice

Example: Deploying Azure Local “just in case” when all requirements can be met in Sovereign Public Cloud

How to Avoid:

Start with simplest model that meets requirements
Add complexity only when justified
Consider management overhead of multiple models
