 # Load Balancer and Availability Zones

 Additionally, the use of zonal frontends directly for load balanced endpoints within each zone is supported. You can use this configuration to expose per zone load-balanced endpoints to individually monitor each zone. For public endpoints, you can integrate them with a DNS load-balancing product like [Traffic Manager](../traffic-manager/traffic-manager-overview.md) and use a single DNS name.

 ### Tolerance to zone failure
 
-- A **zone redundant** Load Balancer can serve a zonal resource in any zone with one IP address.  The IP can survive one or more zone failures as long as at least one zone remains healthy within the region.
+- A **zone redundant** frontend can serve a zonal resource in any zone with a single IP address.  The IP can survive one or more zone failures as long as at least one zone remains healthy within the region.
 - A **zonal** frontend is a reduction of the service to a single zone and shares fate with the respective zone. If the zone your deployment is in goes down, your deployment will not survive this failure.
 
-It is recommended you use zone-redundant Load Balancer for your production workloads.
+Members in the backend pool of a load balancer are normally associated with a single zone (e.g. zonal virtual machines).  A common design for production workloads would be to have multiple zonal resources (e.g. virtual machines from zone 1, 2, and 3) in the backend of a load balancer with a zone-redundant frontend.
