You've configured the resilient infrastructure that Contoso's AI team needs to deploy fraud detection models to production with confidence in their availability guarantees. By implementing multi-region Microsoft Foundry hubs, you created independent control planes that can operate autonomously when one region experiences an outage. The geo-redundant storage configuration with soft delete and resource locks protects 50 TB of irreplaceable training datasets against both infrastructure failures and accidental deletions. Your Azure Container Registry Premium deployment with geo-replication ensures that 8-GB model containers are available locally in each region, eliminating cross-region network dependencies during inference operations.

Three key decisions shaped this infrastructure design. First, you selected active-passive hub deployment to balance 99.95% availability requirements with cost optimization, recognizing that the secondary hub doesn't need full compute capacity until failover occurs. Second, you chose GRS storage redundancy over GZRS after confirming that the 30-minute RPO tolerance didn't justify the more cost of zone-level protection within the primary region. Third, you implemented deployment pipeline checks that verify container image replication before updating secondary region compute clusters, preventing version drift during the normal asynchronous replication window.

The infrastructure you built reduces Contoso's recovery time objective from hours (manual rebuild) to minutes (automatic failover) and improves data durability from 11 nines (single-region LRS) to 16 nines (geo-redundant). Business stakeholders gain confidence in SLA compliance, operations teams eliminate manual failover procedures, and security teams verify that training data survives regional disasters.

Next steps

Continue building production-ready AI operations:

  • Monitor Microsoft Foundry resources to implement observability for your resilient infrastructure with metrics, logs, and alerts that detect regional failures before they impact users
  • Optimize costs for Azure AI workloads to fine-tune your multi-region spending by analyzing compute utilization patterns and adjusting reserved capacity allocations
  • Implement MLOps with Azure Machine Learning to automate model deployment pipelines that coordinate updates across multiple regions with validation gates
