About This Architecture

Dual-region disaster recovery architecture spanning OCI Riyadh primary and OCI Jeddah DR regions with synchronized SQL databases and cross-region failover capabilities. Traffic flows from users through Internet Gateways and WAF policies to load-balanced application VMs in public subnets, with database servers in private subnets replicating data across regions via DRG connectivity. Azure Monitor and Key Vault provide observability and secrets management across both resource groups, ensuring compliance and rapid recovery objectives. Fork this diagram to customize subnet ranges, add additional regions, or integrate with Azure Site Recovery for automated failover orchestration. The architecture demonstrates zone-redundant design with five application VMs per region and synchronized SQL Database replicas for RPO/RTO optimization.

How do I design a multi-region disaster recovery architecture on Azure with database replication and automatic failover?

This diagram shows a dual-region DR setup spanning OCI Riyadh (primary) and Jeddah (DR) with synchronized SQL Database replicas connected via DRG, load-balanced application VMs in public subnets, and Azure Monitor/Key Vault for observability and secrets. Users access the primary region through WAF-protected Internet Gateways, with automatic failover to the DR region when primary becomes unavailabl
