Hybrid VPN + ExpressRoute — Azure Architecture Template
ExpressRoute primary connectivity with a site-to-site VPN failover path into a core VNet with private DNS resolution.
Why this architecture works
- ExpressRoute carries production traffic with predictable latency and an SLA; VPN is the warm standby path
- Coexisting gateways mean failover is routing convergence, not an emergency change ticket
- Route tables keep on-prem prefixes pointed at the right gateway pair deterministically
- DNS Private Resolver bridges on-prem and Azure name resolution in both directions
- Network Watcher connection monitor continuously probes both paths and alerts on degradation
