Multi-Region and Data Residency

QNSP supports multi-region deployment with data residency controls.

Region model

• Each region operates independently
• Cross-region replication is opt-in
• Data residency enforced at tenant level

Data residency

Tenants can configure:

• Primary region for data storage
• Allowed regions for processing
• Replication restrictions

Residency enforcement

• Storage service respects region constraints
• KMS keys bound to region
• Audit logs stored in designated region

Add-ons

Region-related add-ons:

• region-residency-enforcement: Strict residency controls
• failover-region: Cross-region failover capability

Configuration

Set via tenant configuration:

{
  "dataResidency": {
    "primaryRegion": "ap-southeast-1",
    "allowedRegions": ["ap-southeast-1", "ap-northeast-1"]
  }
}
