Public Preview: Azure ExpressRoute resiliency guard

Azure ExpressRoute resiliency guard is now available in public preview for ExpressRoute virtual network gateways. The new resiliency model property lets you specify whether a gateway is intended for a single-homed or multi-homed configuration, helping align your deployment with the resiliency requirements of your workloads.

For multi-homed gateways, resiliency guard guides you to connect either two ExpressRoute circuits in different peering locations or an ExpressRoute Metro circuit. Portal guidance and configuration safeguards help identify incomplete setups and reduce the risk of changes that could weaken gateway resiliency. Single-homed configurations remain available for workloads that do not require multi-site resiliency.
