Resiliency
insights is an assessment capability designed to measure your network's
reliability for ExpressRoute workloads. At the core of this capability is the resiliency
index, a percentage score calculated based on factors such as route
resilience, zone-redundant gateway usage, advisory recommendations, and
resiliency validation tests. This index evaluates the control plane resiliency
of the ExpressRoute connectivity between your Virtual Network Gateway and
on-premises network(s). By analysing and improving this index, you can enhance
the robustness and reliability of your connectivity to Azure workloads through
ExpressRoute.
