Multi-region customer scenarios

These examples show how the framework moves from a business or technical driver to a governed regional and workload decision. They are illustrative, not customer-specific recommendations.

Scenario Driver Archetype Connectivity profile Outcome
Regulated bank adopts a new in-country region Data residency and regulation Hybrid-Connected Applications Minimal Regional Hub Qualified for defined requirements; selective relocation.
AI team requires a specific model or GPU SKU Service, AI model, SKU, and quota availability Isolated or Connected Cloud-Native or AI Applications Disconnected Spokes Qualified for the AI workload; net-new deployment.
Acquisition brings an estate in another geography Business growth Interconnected Application Portfolios Remote Hub Connected or Minimal Regional Hub Candidate until dependencies are known; workloads stay in place at first.
Datacenter exit accelerates migration Datacenter and connectivity event Hybrid-Connected Applications No new profile; the existing hub is reused Workloads land in the existing qualified region.

Regulated bank adopts a new in-country region#

A financial-services organization operates workloads outside its home country. A new Azure region opens in-country while regulatory or business requirements create a need for certain data or services to remain there.

Step Outcome
Driver Data residency and regulatory requirements; new in-country Azure region.
Deciding checks Check 2 confirms mandatory location requirements. Check 3 identifies affected workloads and dependencies. Check 4 validates required regional capabilities, services, zones, access, and constraints.
Qualification The region can be qualified for defined Hybrid-Connected workload requirements while other portfolio workloads remain candidates until their dependencies are understood.
Workload Landing Zone archetype Hybrid-Connected Applications
Connectivity profile Minimal Regional Hub where selected local capabilities are required and existing hybrid connectivity can be reused where reachability and resiliency requirements permit.
Placement In-scope workloads can relocate selectively; other workloads can remain in place. Recovery architecture remains a workload-specific decision.
Takeaway

A new in-country region can be qualified for defined workload requirements without forcing portfolio-wide relocation. If the new region is nonpaired, design the recovery path explicitly. See Resiliency scenarios.

AI team requires a specific model or GPU SKU#

A product team requires an AI model, GPU SKU, or related Azure service that is unavailable in the organization's existing regions or constrained by quota.

Step Outcome
Driver AI model, service, SKU, or quota availability.
Deciding checks Check 1 confirms the business requirement. Check 2 validates data and compliance constraints. Check 4 validates current model, service, SKU, zone, regional access, and quota support.
Qualification The region can be qualified for the defined AI workload requirements. It remains conditional for requirements that depend on private connectivity until that design is known and validated.
Workload Landing Zone archetype Isolated Cloud-Native or AI Applications where the workload is self-contained; Connected Cloud-Native or AI Applications where private enterprise dependencies are required.
Connectivity profile Disconnected Spokes where the workload is self-contained; a connected profile only where actual dependencies justify it.
Placement Net-new deployment. Revalidate current model, SKU, service, regional access, and quota support at decision time.
Takeaway

Qualify against the requirements that exist today; do not introduce enterprise connectivity or regional platform capabilities before a workload requirement justifies them.

Acquisition brings an estate in another geography#

An acquisition introduces a portfolio of interdependent applications, shared data, and local users in a geography where the organization has little or no existing Azure platform presence.

Step Outcome
Driver Business expansion through acquisition.
Deciding checks Check 1 confirms the business need. Check 2 evaluates local data obligations. Check 3 maps portfolio-level dependencies, shared services, and connectivity requirements.
Qualification Candidate while material dependencies remain unknown; qualified against defined portfolio requirements once sufficient discovery is complete.
Workload Landing Zone archetype Interconnected Application Portfolios
Connectivity profile Remote Hub Connected where cross-region dependencies are acceptable; Minimal Regional Hub where aggregate east-west traffic, shared services, latency, or independence requirements justify local capability.
Placement Workloads can remain in place initially and relocate selectively as business and integration requirements become known.
Takeaway

Aggregate portfolio dependencies determine the appropriate regional connectivity profile; application count or acquisition status does not.

Datacenter exit accelerates migration#

A colocation contract is ending. Hybrid-connected applications must leave the datacenter, and the organization asks whether the event also requires adoption of another Azure region.

Step Outcome
Driver Datacenter and connectivity event.
Deciding checks Check 3 identifies applications and components that must move together. Step 3 validates hybrid connectivity, datacenter and user geography, reachability, resiliency, and whether existing connectivity can support the target design.
Qualification The existing target region can remain qualified for the identified workload requirements while an additional region remains a candidate for future use.
Workload Landing Zone archetype Hybrid-Connected Applications
Connectivity profile No new profile. Continue to use the existing strategic geographic hub where it satisfies requirements; do not create a new regional hub solely because another Azure region is available.
Placement Most workloads can land in the existing qualified region where it satisfies their requirements. Revisit the additional regional option when requirements change.
Takeaway

Remaining in an existing qualified region is a valid outcome. An additional region can remain an option rather than automatically becoming a deployment project.
