Zone-redundant NAT Gateway
Since subnets are regional, not zonal, and can only be associated with a maximum of one NAT gateway, it seems that deployments would be much simpler if NAT gateways were supported in a zone-redundant mode.
This is something you offer with Standard Load Balancer, so why can't it be provided by NAT gateways?
Currently, I either must: (1) forego any failure isolation promises and go with a regional NAT, or (2) double or triple the number of subnets I manage just so a zone-isolated NAT can be assigned to each. That makes a complicated, messy deployment that wasn't required for zone support w/out a NAT gateway.
thank you for the feedback. We understand the gap with regional subnets and zone-spanning VMSS. Virtual Network NAT needs to evolve to allow traffic from a zonal resource to be aligned with the zone when customers span their resources across zones.
