The Azure Files update in 2023 introduced Azure Active Directory support for REST API, enabling SMB file share access with OAuth authentication. This advancement improved the scalability of Azure Virtual Desktop by increasing the root directory handle limit from 2,000 to 10,000. Additionally, the public preview of geo-redundant storage for large file shares enhanced capacity and performance, while the Premium Tier now guarantees a 99.99% uptime SLA for all premium shares.

In 2022, Azure AD Kerberos authentication for hybrid identities was a highlight, as it built upon FSLogix profile container support. Also, SUSE Linux gained compatibility with SAP HANA System Replication and Pacemaker.

In 2021, premium Azure file shares received heightened baseline and burst IOPS, catering to POSIX-compliant, distributed file shares. NFSv4.1 protocol was enabled for premium file shares, enhancing flexibility and alignment with standard shares. SMB Multichannel was introduced, offering parallel connections for network optimization, along with SMB 3.1.1 with additional encryption modes. Azure Files started supporting storage reservations for premium, hot, and cool tiers, optimizing cost efficiency. The portal experience for domain joining was simplified, and Azure Files management became accessible through the control plane, streamlining management actions through various tools.

These updates represent a continual effort by Microsoft to improve the functionality, performance, and security of Azure Files, reflecting their commitment to providing a robust and efficient file-sharing service.

Enhanced Features of Azure Files

Azure Active Directory Support for REST API

Azure Active Directory (Azure AD) support for REST API is a significant enhancement as it enables Server Message Block (SMB) file share access using OAuth authentication. This feature enhances security by allowing only authenticated users to access file shares. It is particularly beneficial for organizations that have already integrated Azure AD and want to leverage it for secure file access.

Increased Root Directory Handle Limit

The scalability of Azure Virtual Desktop was improved by increasing the root directory handle limit from 2,000 to 10,000. This enhancement allows for more simultaneous connections to the root directory, enabling larger organizations to use Azure Virtual Desktop more effectively.

Geo-Redundant Storage for Large File Shares

The introduction of geo-redundant storage for large file shares in public preview is another noteworthy update. This feature boosts both the capacity and performance of file shares, making it easier for organizations to manage large amounts of data across different geographical locations.

99.99% Uptime SLA for Premium Shares

The Premium Tier of Azure Files now guarantees a 99.99% uptime Service Level Agreement (SLA) for all premium shares. This improvement ensures higher availability and reliability of premium file shares, which is crucial for businesses that require continuous access to their data.
