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.
