 [NFS 3.0 protocol support on Azure Blob storage](https://docs.microsoft.com/en-us/azure/storage/blobs/network-file-system-protocol-support) is now in Preview. This service is best suited for large scale read-heavy sequential access workload where data will be ingested once and minimally modified further.
