Azure Blob Storage vs Azure File Storage:

Choosing the Right Storage Solution for Your Business

Azure Storage

In today’s digital age, data storage is an essential part of any business strategy. As more and more businesses move their operations to the cloud, choosing the right storage solution can make a significant impact on your organization’s efficiency and productivity. Azure, Microsoft’s cloud computing platform, offers two primary storage solutions: Azure Blob Storage and Azure File Storage.

In this article, we’ll take a closer look at both Azure Blob Storage and Azure File Storage and help you decide which one is the best fit for your business.

Choosing the Right Storage Solution

Now let’s explore the key differences between Azure Blob Storage and Azure File Storage.

Structure

Azure Blob Storage stores data as blobs within containers, allowing for a flat storage structure. In contrast, Azure File Storage uses a hierarchical structure, with directories and subdirectories, similar to a traditional file system.

Access

Blob Storage supports REST APIs, Azure Storage SDKs, and Azure Storage Explorer for data access. File Storage allows access via the SMB protocol, enabling you to mount file shares directly to your virtual machines or on-premises systems.

Scalability

Blob Storage can scale to store petabytes of data, with individual blobs up to 4.75 TB in size. File Storage, while still scalable, has a maximum share size of 100 TiB.

Performance

Blob Storage provides higher throughput and lower latency than File Storage. However, File Storage offers better performance for small file read and write operations, which can be crucial for specific applications.

Security

Both services provide data encryption at rest and in transit. However, Blob Storage also supports object-level access control through shared access signatures, while File Storage relies on share-level access control.

When choosing between Azure Blob Storage and Azure File Storage, it’s important to consider your business’s needs. If you need to store large amounts of unstructured data such as videos, images, and audio, Azure Blob Storage is the best choice. If you need to store structured data such as application data and virtual machine files and share files with Windows and Linux clients, Azure File Storage is the better option.

How can I connect to Azure Blob Storage?

With Azure Blob Storage access is provided over HTTPS, so you cant traditionally mount Blob Storage as a mapped network drive to a Virtual Machine or Users desktop. 

 

You can however browse all the Azure Blobs contained within this Storage Account through your web browser, using Microsoft’s Azure Storage Explorer, the Azure Storage Rest API, Powershell or even the Azure CLI. Alternatively, you can use our software, Cloud Storage Manager to do the same thing and more.

 

How can I connect to Azure File Storage?

As stated before, Azure File Services is more like your standard file server, in that you can create multiple network shares with folders and files within. These shares can of course be mapped directly to your machines as a network drive using the SMB protocol. To map a network drive to an Azure File Share, Microsoft lets you create a login script direct from the Azure Portal using powershell to connect the share.

Here is an example powershell script to connect an Azure File share to a users computer as a Y drive mapping.

$connectTestResult = Test-NetConnection -ComputerName storageaccountname.file.core.windows.net -Port 445

if ($connectTestResult.TcpTestSucceeded) {

    # Save the password so the drive will persist on reboot

    cmd.exe /C “cmdkey /add:`”storageaccountname.file.core.windows.net`” /user:`”localhost\storageaccoun`” /pass:`”longpasswordabcdefghijklmnopqrstuvwxyz`””

    # Mount the drive

    New-PSDrive -Name Y -PSProvider FileSystem -Root “\\storageaccountname.file.core.windows.net\fileservicestest” -Persist

} else {

    Write-Error -Message “Unable to reach the Azure storage account via port 445. Check to make sure your organization or ISP is not blocking port 445, or use Azure P2S VPN, Azure S2S VPN, or Express Route to tunnel SMB traffic over a different port.”

}

With Azure Files you can also set NTFS permissions on the shares, folders and files. Additionally you can integrate this service with your Azure AD so that permissions can be set using normal AD groups and users. 

One thing that differentiates Azure File Services from an on-premise File Server is that you can access the folders and files from anywhere with an internet connection.

Allow access to Azure Storage Account using a Shared Access Signature

The Shared Access Signature can be created to allow access over HTTP or HTTPS for a limited time to any of the Azure Storage Services. This includes Blob, File, Queue and Table Services. 

You can be granular with the access you want to provide. Perhaps you have a third party that you only want to give access to your data and  certain services for a fixed amount of time. 

Options you can choose are;

  • Allowed Services;
    • Blob
    • File
    • Queue
    • Table
  • Allowed Resource Types
    • Service
    • Container
    • Object
  • Allowed Permissions
    • Read
    • Write
    • Delete
    • List
    • Add
    • Create
    • Update
    • Process
    • Immutable Storage
Choose this options carefully, as you can see you can be as granular as you want to allow access to your Azure Storage Accounts. 

Whats a Use Case Example for Azure Blob Storage?

Azure Blob Storage has several use cases. Its great for the following types of data storage;

  • Serving documents, images or videos direct to a browsers.
  • Storing of files for quick and easy access 
  • Streaming video and audio
