Published: November 03, 2025 17:30:04 UTC Link: Public Preview: Azure NetApp Files Object REST API

Update ID: 516643 Data source: Azure Updates API

Categories: In preview, Storage, Azure NetApp Files, Features

Summary:

What was updated
Azure NetApp Files has introduced a Public Preview of the Object REST API, an S3-compatible REST API interface.
Key changes or new features
The new Object REST API enables seamless access to Azure NetApp Files storage using S3-compatible REST calls, bridging traditional file-based storage with modern cloud-native object storage paradigms. This allows developers and applications to interact with existing file shares as objects, facilitating new cloud service integrations and workflows. The API leverages Microsoft Fabric for integration, enhancing performance and scalability.
Target audience affected
Developers building cloud-native applications requiring S3-compatible object storage interfaces, and IT professionals managing hybrid storage environments who want to extend Azure NetApp Files capabilities beyond traditional file protocols.
Important notes if any
This feature is currently in Public Preview, so users should evaluate it in non-production environments and provide feedback. Integration with Microsoft Fabric suggests optimized performance but may require familiarity with Azure networking and security configurations. Users should monitor Azure updates for GA announcements and additional feature support.

Details:

The recent Public Preview of the Azure NetApp Files Object REST API introduces an S3-compatible REST interface to Azure NetApp Files (ANF), enabling seamless object storage access alongside traditional file-based protocols. This update addresses the growing need for hybrid storage solutions that combine the performance and enterprise features of ANF with the flexibility and ecosystem compatibility of object storage.

Background and Purpose
Azure NetApp Files has been widely adopted for high-performance file storage scenarios using NFS and SMB protocols, primarily targeting lift-and-shift enterprise applications and workloads requiring low latency and high throughput. However, modern cloud-native applications increasingly rely on object storage APIs, such as Amazon S3, for scalable, schema-less data storage and integration with cloud services. The Object REST API aims to bridge this gap by providing an S3-compatible interface directly on ANF volumes, allowing customers to leverage their existing file-based data and infrastructure investments while enabling new cloud-native workflows without migrating data to separate object stores.

Specific Features and Detailed Changes

S3-Compatible REST API: The Object REST API supports standard S3 operations (PUT, GET, DELETE, LIST) enabling object storage semantics on ANF volumes.
Data Access Flexibility: Customers can access the same data via traditional file protocols (NFS/SMB) and the S3-compatible API, facilitating hybrid workloads.
Microsoft Fabric Integration: The API is integrated with Microsoft Fabric, ensuring consistent identity and access management, security, and networking capabilities within the Azure ecosystem.
Performance and Scalability: Leveraging ANF’s underlying high-performance storage infrastructure, the Object REST API supports enterprise-grade throughput and low latency for object operations.

Technical Mechanisms and Implementation Methods
The Object REST API is implemented as a service layer on top of Azure NetApp Files volumes, translating S3 REST calls into file system operations on the underlying ANF storage. This involves:

Protocol Translation: Mapping S3 object operations to file system actions (e.g., objects as files or directories).
Metadata Management: Maintaining S3-compatible metadata and bucket/object namespace semantics on top of the file system namespace.
Authentication and Authorization: Utilizing Microsoft Fabric’s identity services to authenticate API calls and enforce access controls consistent with Azure RBAC and ANF security models.
Data Consistency: Ensuring strong consistency between file-based and object-based access paths to prevent data divergence.

Use Cases and Application Scenarios

Hybrid Workloads: Applications requiring both file and object access to the same data sets, such as media processing pipelines that use SMB/NFS for editing and S3 API for distribution.
Cloud-Native Application Modernization: Enabling legacy applications to expose data via S3 APIs without migrating off ANF.
Data Analytics and AI: Facilitating integration with Azure services and third-party tools that consume S3 object storage for analytics and machine learning workloads.
Backup and Archival: Using S3-compatible APIs for backup solutions that natively support object storage protocols.

Important Considerations and Limitations

Preview Status: As a public preview, the API may have feature limitations, performance tuning requirements, and potential breaking changes before general availability.
Compatibility Scope: While S3-compatible, some advanced S3 features or extensions may not be fully supported initially.
Security Configurations: Proper configuration of Microsoft Fabric integration and Azure RBAC is essential to secure access.
Data Consistency Model: Users should understand the consistency guarantees when accessing data via different protocols simultaneously.

Integration with Related Azure Services

Azure Active Directory (AAD): For identity management and access control via Microsoft Fabric integration.
Azure Monitor and Azure Security Center: For monitoring API usage, performance metrics, and security posture.
Azure Data Services: Enables seamless data ingestion and processing with services like Azure Synapse, Azure Dat
