Compare access to Azure Files, Blob Storage, and Azure NetApp Files with NFS

This article provides a comparison between each of these offerings if you access them through the Network File System (NFS) protocol. This comparison doesn't apply if you access them through any other method.

For more general comparisons, see this article to compare Azure Blob Storage and Azure Files, or this article to compare Azure Files and Azure NetApp Files.


Category Azure Blob Storage Azure Files Azure NetApp Files
Use cases Blob Storage is best suited for large scale read-heavy sequential access workloads where data is ingested once and minimally modified further.

Blob Storage offers the lowest total cost of ownership, if there is little or no maintenance.

Some example scenarios are: Large scale analytical data, throughput sensitive high-performance computing, backup and archive, autonomous driving, media rendering, or genomic sequencing.
Azure Files is a highly available service best suited for random access workloads.

For NFS shares, Azure Files provides full POSIX file system support and can easily be used from container platforms like Azure Container Instance (ACI) and Azure Kubernetes Service (AKS) with the built-in CSI driver, in addition to VM-based platforms.

Some example scenarios are: Shared files, databases, home directories, traditional applications, ERP, CMS, NAS migrations that don't require advanced management, and custom applications requiring scale-out file storage.
Fully managed file service in the cloud, powered by NetApp, with advanced management capabilities.

Azure NetApp Files is suited for workloads that require random access and provides broad protocol support and data protection capabilities.

Some example scenarios are: On-premises enterprise NAS migration that requires rich management capabilities, latency sensitive workloads like SAP HANA, latency-sensitive or IOPS intensive high performance compute, or workloads that require simultaneous multi-protocol access.
