Azure Storage Files: Overview

Azure Storage offers a range of robust, scalable, and highly available cloud storage solutions. This section provides an overview of the various file storage services available within Azure Storage, helping you choose the right option for your application's needs.

Key Services: Azure Storage provides distinct services for different types of data: Blob Storage, File Storage, Queue Storage, and Table Storage. This document focuses primarily on Blob and File Storage.

Azure Blob Storage

Azure Blob Storage is Microsoft's cloud object storage solution. It is optimized for storing massive amounts of unstructured data, such as text or binary data. Common use cases include:

Serving images or documents directly to a browser.
Storing files for distributed access.
Streaming video and audio.
Storing data for backup, restore, disaster recovery, and archiving.
Storing data for analysis by an on-premises or Azure-hosted service.

Blob Types

Blob Storage supports three types of blobs:

Block blobs: Optimized for storing large amounts of unstructured data, such as media files or documents.
Append blobs: Optimized for append operations, such as logging data from a virtual machine.
Page blobs: Optimized for random read/write operations and used to support IaaS virtual machine disks.

For more details, see Azure Blobs.

Azure Files

Azure Files offers fully managed cloud file shares that are accessible via the industry-standard Server Message Block (SMB) protocol, and Network File System (NFS) protocol. This allows you to lift and shift on-premises applications that rely on file shares to Azure. Key features include:

Shared access via SMB and NFS.
Mountable on Windows, Linux, and macOS.
Managed by Azure, removing the need to manage underlying infrastructure.
Ideal for shared configuration files, application settings, and development/debugging tools.

For more details, see Azure Files.

Choosing Between Blob and Files:

Use Blob Storage for storing and accessing large amounts of unstructured data like images, videos, and documents.
Use Azure Files when you need a managed file share accessible via SMB/NFS, often for lifting and shifting existing applications.

Other Storage Services

While this document focuses on file and blob storage, Azure Storage also includes:

Azure Queue Storage: For storing large numbers of messages that can be processed asynchronously. See Azure Queues.
Azure Table Storage: For storing large amounts of semi-structured data. See Azure Tables.
