Azure offers Azure NetApp Files (ANF) and Azure File Storage (AFS) as cloud-based file storage solutions, but they serve different use cases and performance needs. Below is a detailed comparison to help choose the best option.
✅ 1. What is Azure NetApp Files (ANF)?
Azure NetApp Files (ANF) is a high-performance, enterprise-grade file storage service built on NetApp technology and offered as a first-party Azure service.
What it is: A fully managed, high-performance, enterprise-grade NAS (Network Attached Storage) service. It's built on NetApp's ONTAP storage operating system, providing a familiar experience for users accustomed to on-premises NetApp deployments.
🔹 Key Features
✔ Ultra-fast performance (supports low-latency workloads).
✔ Supports NFS (v3, v4.1) & SMB protocols.
✔ Provides dynamic scaling based on workload needs.
✔ Ideal for high-performance computing (HPC), SAP HANA, AI/ML, and databases.
✔ Built-in snapshots, backup & disaster recovery (DR).
✔ Region-based availability (Not available in all Azure regions).
🔹 Best Use Cases
✅ High-performance workloads like SAP HANA, Oracle, AI/ML, VDI.
✅ Large-scale enterprise applications that need low-latency & high IOPS.
✅ Hybrid cloud storage with on-prem NetApp integration.
✅ Disaster recovery & backup with built-in snapshots.
🔹 Pros & Cons
| ✅ Pros | ❌ Cons |
|---|---|
| Ultra-low latency, high performance | Expensive for small workloads |
| Supports NFS & SMB protocols | Not available in all Azure regions |
| Automatic scalability & high availability | Requires manual quota reservations |
| Enterprise-grade data protection & snapshots | More complex setup than AFS |
✅ 2. What is Azure File Storage (AFS)?
Azure File Storage (AFS) is a fully managed file-sharing service in Azure, supporting SMB & NFS protocols.
What it is: A fully managed file share service that offers cloud-native SMB file shares. It's built on the same Azure storage platform as other services like Azure Blobs.
🔹 Key Features
✔ SMB (Server Message Block) & NFS support.
✔ Can be accessed from on-prem using VPN or ExpressRoute.
✔ Integration with Azure File Sync (AFS) for hybrid cloud solutions.
✔ Cheaper than Azure NetApp Files for standard file shares.
✔ Supports backup and snapshot features.
🔹 Best Use Cases
✅ File shares for applications that need SMB or NFS access.
✅ Shared storage for Virtual Machines (VMs) & Kubernetes.
✅ Backup & archiving (cheaper than ANF for cold storage).
✅ Hybrid cloud storage with Azure File Sync (AFS).
🔹 Pros & Cons
| ✅ Pros | ❌ Cons |
|---|---|
| Fully managed file sharing service | Higher latency than ANF |
| Cheaper than Azure NetApp Files | Performance limits for high IOPS workloads |
| Works with Azure File Sync for on-prem Windows Servers | Not suitable for HPC or SAP workloads |
| Easy to deploy and use | Lacks enterprise-grade snapshots & DR |
🚀 Key Differences: ANF vs AFS
| Feature | Azure NetApp Files (ANF) | Azure File Storage (AFS) |
|---|---|---|
| Performance | 🔥 Ultra-low latency, high IOPS | ⚡ Good for file sharing, moderate IOPS |
| Use Case | Enterprise apps, SAP HANA, HPC, AI/ML | SMB/NFS file shares, backups, general workloads |
| Protocol Support | ✅ NFS v3/v4.1, SMB | ✅ SMB & NFS |
| Scalability | 🚀 Automatic scaling | 🔄 Scalable but lower limits |
| Hybrid Cloud | ✔ Works with on-prem NetApp | ✔ Works with Azure File Sync |
| Snapshots & Backup | ✅ Enterprise-grade snapshots | ✅ Basic snapshots & backups |
| Cost | 💰 Expensive (Premium Tier) | 💵 Cheaper (Standard Tier) |
💡 Which One is the Best?
| Use Case | Best Option |
|---|---|
| High-performance workloads (SAP HANA, AI/ML, Oracle, VDI, databases, HPC) | 🚀 Azure NetApp Files (ANF) |
| General file sharing, SMB/NFS workloads, app storage | 🔄 Azure File Storage (AFS) |
| Hybrid cloud with Windows File Servers | 🔗 Azure File Storage (AFS) with Azure File Sync |
| Backup & disaster recovery for enterprise workloads | 🛡️ Azure NetApp Files (ANF) (Snapshots) |
| Cheaper cloud file storage (low IOPS workloads) | 💰 Azure File Storage (AFS) |
🛠Final Recommendation
- Use Azure NetApp Files (ANF) if you need high performance, low latency, and enterprise features like SAP HANA or AI workloads.
- Use Azure File Storage (AFS) if you need a cheaper, SMB/NFS-based storage solution for VMs, applications, and general file shares.
