Frontend and backend VNet separation follows defense-in-depth principles with NVA inspection points providing policy enforcement between security zones. This architecture supports regulatory requirements while enabling application performance optimization.
SD-WAN policies route traffic based on application requirements while BGP communities enable granular path control for different service classes. ExpressRoute circuits provide primary connectivity with automated failover to secondary regions.
Hybrid DNS strategy maintains on-premises Active Directory integration while enabling cloud-native Private Link resolution. Conditional forwarding ensures optimal performance for both corporate and Azure resources.
Network architecture assumes breach scenarios with identity verification required at every network boundary. Frontend VNets provide initial traffic inspection while backend VNets maintain data protection through additional security controls.
Architecture patterns include automated logging, change management integration, and policy enforcement mechanisms required for SOC 2, PCI DSS, and healthcare regulatory frameworks.
- DNS resolution latency reduced by 20ms average for Azure resources
- Application response times improved 15% through optimized routing
- Cross-region communication maintained <50ms latency for business-critical applications
- DNS management overhead reduced 60% through automation
- Security policy deployment time decreased from days to hours
- Network troubleshooting accelerated through comprehensive documentation
Note: These patterns represent production-tested designs implemented across enterprise Azure deployments. All diagrams and configurations have been validated in real-world environments with regulatory compliance requirements.
