DFS Namespaces with root consolidation work well when migrating traditional file servers to Azure Files because users keep a stable, friendly path while the underlying storage changes. A clustered DFS Namespace can also provide additional availability. For a cloud-native Azure environment, is there a managed or simpler alternative to running DFS Namespace on IaaS, or would we still need to deploy multiple Windows servers and recreate the traditional design? The goal is to preserve stable drive mappings, potentially while moving toward Microsoft Entra ID authentication for the storage accounts.

There doesn't appear to be a native Azure PaaS replacement for DFS Namespaces. If users need a stable friendly name for mapped drives, DFS-N is still the practical option, especially when the mappings are domain-based. You would likely need to run it on Windows VMs, with more than one for redundancy. Since domain controllers are often already deployed in pairs, hosting DFS-N there may be simpler than maintaining separate servers. For the storage layer, use Azure Files with ZRS or GZRS so the shares are also protected across availability zones or regions.
There is no out-of-the-box cloud service that provides the same private, stable namespace functionality as DFS-N. A private load balancer in front of multiple namespace servers might be technically possible, but it may not be a supported Microsoft architecture. If the requirement is simply keeping the existing friendly path unchanged, rebuilding DFS-N in Azure IaaS is probably the most predictable approach.
That matches what we're seeing. The environment may eventually move toward Entra ID-only authentication, but there doesn't seem to be an equivalent namespace service in that model. Managing mappings through Intune would not provide the same seamless failover behavior.
