Azure Files is best for storing large files and offers higher storage capacity, while SharePoint is better for document collaboration and teamwork.
Azure Files allows secure access from an internal network, making it a strong option for companies concerned about data privacy and access control. SharePoint, however, makes it much easier for users to work together on files in real time.
Choosing the right option depends on the size of your files, how you want them accessed, and whether your team values collaboration over storage capacity. This article explains the main differences to help businesses pick the best platform for their needs.
Overview of Azure Files and SharePoint
Azure Files and SharePoint are two cloud storage options from Microsoft, each designed for different use cases and needs. They offer unique features, integration capabilities, and management tools that are important for organizations choosing between them.
What Is Azure Files
Azure Files is a cloud-based file sharing service that is part of the Microsoft Azure storage platform. It allows users to create file shares in the cloud, which can be accessed from anywhere via standard SMB and NFS protocols.
Azure Files supports secure and scalable storage, making it suitable for storing large amounts of unstructured data. It can be used for file storage, lift-and-shift applications, and replacing or extending on-premises file servers. The service integrates with on-premises networks using Azure File Sync, providing a hybrid solution.
Key features include:
- SMB and NFS protocol support
- Easy integration with Windows, Linux, and macOS
- Integration with Azure Active Directory
- Scalability up to hundreds of terabytes per share
Azure Files is often used by organizations that need centralized storage with direct file system access for applications, users, or backup solutions.
What Is SharePoint
SharePoint, especially SharePoint Online, is part of the Microsoft 365 suite. It is a collaboration platform designed for document management, sharing, and editing in real-time within teams and across organizations.
SharePoint is browser-based, meaning users access files and folders through a web interface or Microsoft Teams. It emphasizes collaboration, version control, co-authoring, and metadata tagging. Permissions are handled at multiple levels, allowing fine-grained access to documents and sites.
Important features include:
- Document libraries with rich metadata
- Integration with Microsoft 365 apps
- Real-time collaboration and co-authoring
- Version history and advanced permissions
SharePoint is ideal for sharing, managing, and collaborating on documents, especially in environments where teamwork, workflow automation, and compliance are needed.
Core Differences
Azure Files and SharePoint serve different scenarios within Microsoft’s cloud ecosystem. The table below highlights core differences:
| Feature | Azure Files | SharePoint Online |
|---|---|---|
| Primary Use | Cloud file shares | Document collaboration |
| Access Method | SMB/NFS protocols, mapped drives | Web browser, Teams, Office apps |
| Collaboration | Basic, file sharing | Advanced, co-authoring |
| Integration | File servers, enterprise apps | Microsoft 365 suite |
| Permissions | Folder/file level | Folder/file/site level |
| Best For | Large unstructured data, backups, legacy apps | Teamwork, workflows, intranet sites |
Azure Files is chosen when organizations need file-level access that mimics traditional file servers.

Architecture and Deployment Models
Azure Files and SharePoint use different deployment models and architectures. Both solutions can handle file storage, but their approaches to cloud integration, hybrid support, and on-premises compatibility differ in important ways.
Cloud-Native vs Hybrid Deployment
Azure Files is built to work natively in the cloud. It stores file shares in an Azure storage account, allowing access over SMB or REST protocols. Users can mount these shares to Windows, Linux, and macOS devices, whether on-premises or in Azure VMs.
SharePoint Online is also a cloud-native service delivered through Microsoft 365. It lets users store, share, and collaborate on documents within web portals and integrated apps. Unlike Azure Files, it focuses on document management with version control and collaboration features.
Hybrid deployment is easier with Azure Files. With Azure File Sync, organizations can cache cloud file shares to on-premises file servers. This reduces latency for local access and keeps frequently used files close to users. SharePoint offers limited hybrid support but usually works best as a full cloud service.
On-Premises File Server Integration
Integrating with on-premises file servers is more flexible with Azure Files. Using Azure File Sync, businesses can mirror files from an on-premises server to an Azure File Share. Changes sync in both directions, supporting disaster recovery and cloud migration plans.
Azure Files enables storage expansion and backup without replacing existing file servers. It works well for lifting legacy file server workloads into cloud computing environments. File access through standard SMB protocols means users don’t need to change how they work.
SharePoint can migrate files from an on-premises server, but the integration is less seamless. Files must move into SharePoint document libraries, where traditional file share structures may not be preserved. Blob storage can be used with Azure for archiving, but is not directly integrated into SharePoint for day-to-day file access.

Primary Use Cases
Azure Files and SharePoint each serve key roles in how organizations store files, collaborate on documents, and design their internal communication portals. Their strengths align with different business needs and technical requirements.
File Storage and File Sharing
Azure Files is built for secure, scalable, and accessible file storage. It acts much like a traditional network file server but is hosted in the cloud. This makes it well-suited for storing unstructured data, large files, and legacy file shares.
Businesses use Azure Files when they need robust support for SMB and NFS protocols and compatibility with Windows, macOS, and Linux. File sharing becomes straightforward, with permissions managed at the directory or file level.
It is often chosen for lift-and-shift migrations of on-premises file servers to the cloud. Azure Files is a good fit when organizations want direct access to files from multiple locations without changing how users work.
Document Management and Collaboration
SharePoint specializes in document management and team collaboration. It offers advanced features for version control, access permissions, document workflows, and real-time co-authoring.
Teams use SharePoint to organize files, assign tasks, and communicate changes directly alongside documents. Integration with Microsoft 365 apps, like Word and Teams, makes it simple to share and edit documents together.
SharePoint’s strong search tools help users find files quickly. Document libraries allow for metadata and retention policies, supporting structured document management processes in organizations.
Enterprise Intranet Portals
SharePoint is often used to build intranet portals that support communication and information sharing across an entire business. These portals combine news, announcements, document libraries, calendars, and integration with other business apps.
SharePoint intranet sites can be customized for different departments or roles. Security is handled with user or group-based permissions, providing controlled access to sensitive data.
Azure Files is not designed as a platform for creating intranet portals. Its focus is on file sharing and storage, not interactive or content-rich internal websites for business users. For portals, SharePoint is the established solution.

Collaboration and Productivity Features
SharePoint and Azure Files both allow users to store and manage documents, but they are very different when it comes to how people work together and use productivity tools. One platform focuses on real-time teamwork and strong links to Microsoft 365, while the other sticks to basic file sharing.
Real-Time Collaboration Tools
SharePoint has real-time co-authoring, which means multiple users can open, edit, and save documents together at the same time. This makes working as a group easy because people see each other’s changes instantly.
With SharePoint, there are built-in comments and version history. Users can leave notes right inside Word, Excel, and PowerPoint files. This helps with clear communication and quick feedback.
Azure Files does not offer real-time co-authoring. When someone tries to edit the same file at once, they might overwrite another person’s work. Azure Files does keep basic versioning, but it does not support direct chat, comments, or notifications inside files.
Integration with Microsoft 365 Suite
SharePoint connects with the Microsoft 365 suite, including Word, Excel, PowerPoint, Outlook, and Teams. Users can launch, edit, and share documents in their web browsers or apps without needing to move files elsewhere.
SharePoint document libraries appear directly inside other Microsoft 365 apps, allowing a seamless workflow. Features like file check-in/check-out, custom metadata, workflows, and automated approvals are available with SharePoint.
Azure Files does not integrate directly with the Microsoft 365 suite. Files must be downloaded or opened through desktop apps and changes must be saved back manually. There is no native support for advanced features like automated workflows or metadata tagging.
Teams and OneDrive Integration
SharePoint is deeply connected to both Microsoft Teams and OneDrive for Business. Files stored in Teams chats or channels are saved to SharePoint document libraries. This lets team members share, find, and edit documents without leaving Teams.
OneDrive for Business uses SharePoint on the backend to manage personal and shared files. Features like sharing links, syncing files to desktops, and setting permissions are all supported.
Azure Files can be mapped as a network drive and accessed from Windows machines. However, it does not integrate with Teams or OneDrive in the same way. Users can’t collaborate on files within Teams or share through OneDrive links, limiting options for communication and joint editing.
Security and Compliance
Both Azure Files and SharePoint offer important features to keep data secure and compliant. They each use different methods for permissions, backup, and meeting industry requirements.
Permissions and Access Control
Azure Files uses role-based access control (RBAC) to manage who can view and change files. It supports permissions at the share and directory level with integration into Active Directory. Access can be set for groups or individuals through SMB (Server Message Block) and NTFS permissions.
SharePoint uses its own permissions model with deep integration into Microsoft 365. Users and groups can be given different levels of access, from read-only to full control, on sites, folders, and individual documents. It is easier for teams to collaborate and set sharing controls for both internal and external users.
For both systems, Multi-factor Authentication (MFA) and Single Sign-On (SSO) can be enabled. Audit logs are available to track activities and access by users.
Data Loss Prevention and Backup
Azure Files does not include automatic file backup by default. However, it can be set up with Azure Backup, which allows scheduled snapshots and long-term retention. This protects against accidental deletion or data corruption.
SharePoint saves copies of files through versioning, which lets users recover previous versions. Deleted files go to the recycle bin, where they can be restored for a limited time. SharePoint Online is also backed up by Microsoft, but organizations should use third-party tools or Microsoft 365 features for added data loss prevention if needed.
Both solutions support encryption at rest and in transit. Azure Files provides AES 256-bit encryption and supports SMB encryption. SharePoint uses TLS for network encryption and also encrypts data on disk.
Compliance with Industry Standards
Azure Files and SharePoint are both services offered under Microsoft’s compliance framework. These services meet industry standards such as ISO 27001, HIPAA, and GDPR.
Azure Files is certified for many compliance needs, and organizations can review Microsoft’s compliance documents for specific certifications. Policies for retention and auditing can be set according to regulatory guidelines.
SharePoint offers built-in compliance tools like eDiscovery, Data Loss Prevention (DLP) policies, and retention labels. Administrators can set rules for how data is handled, stored, and deleted for legal or business needs.

| Low Latency | Yes | Moderate |
The ability to choose premium storage in Azure Files gives businesses more control over performance and cost.
Integration with NFS and File Shares
Azure Files supports network protocols like SMB and NFS, making it flexible for many environments. NFS support means Linux-based applications can use Azure Files as a native file share. This is helpful for migration from on-premises file servers and for hybrid cloud deployments.
Azure Files can be mapped as a network drive, making it easy for users to access files just like local folders. File sharing over SMB or NFS allows integration with legacy apps and provides a seamless experience for mixed operating systems.
SharePoint is focused on web-based file access. It does not support traditional network protocols like NFS and is less suited to scenarios where direct file system integration is required. This can limit its use when legacy support or hybrid deployments are important.
Customization and Integration Capabilities
Azure Files and SharePoint offer different levels of customization and integration for business needs. Both solutions support automation and work well with other Microsoft services, but they are built for different types of workflows and user experiences.
Customization for Business Workflows
SharePoint provides built-in tools for customizing document libraries, lists, and workflows. Users can create custom columns, manage metadata, and design approval processes without writing code. This helps with organizing files and improves search capabilities.
SharePoint also integrates with Microsoft 365 apps like Teams and Outlook. Users can set permissions, create custom views, and automate document flows with simple point-and-click options. Managed metadata ensures tagging is consistent across the organization.
Azure Files, in contrast, is a network file share. It does not have the same level of built-in customization as SharePoint. Users can configure shared folders and permissions, but workflow features are limited. Azure Files is best for businesses that want traditional file shares with basic integration to Microsoft 365.
Automation and PowerShell Support
SharePoint Online supports automation through Microsoft Power Automate and built-in workflow tools. Users can set up alerts, routing, and approval processes with minimal setup. More advanced users can automate tasks using PowerShell or the SharePoint API.
