Which cloud file storage alternative best supports Windows workloads?

Azure Files with SMB protocol and Azure Active Directory Domain Services is the strongest Windows-native alternative. It provides Kerberos authentication, ACL inheritance, and integration with enterprise identity providers that FSx for Windows replicates within the AWS ecosystem.

Can I replace Amazon EFS with a managed NFS service on another cloud?

Yes. Google Filestore and OCI File Storage both provide NFSv3/NFSv4 managed shares that serve as functional EFS equivalents. Azure Files now supports NFS 4.1 as well, broadening cross-platform compatibility.

What specialized file storage alternatives exist for HPC and media workloads?

For HPC, Hammerspace and Weka.io provide high-throughput parallel file systems. For media, Nasuni and Panzura offer global namespace capabilities. AWS FSx for Lustre itself is a specialist HPC file system, with IBM Spectrum Scale and DDN IME as on-prem or hybrid alternatives.
