Create a storage account using Azure CLI

In the previous article, we thoroughly explored the features and use cases of Azure Blob Storage—ideal for storing unstructured data such as documents, audio, and video files. However, in certain scenarios, you may require a file-sharing service that enables seamless sharing and access to files across multiple virtual machines and applications. In such cases, Azure Files is an ideal solution.

Overview of Azure Files

Azure Files is a cloud-based file-sharing storage solution provided by Microsoft Azure. It allows you to create file shares in Azure using the Server Message Block (SMB) protocol. With Azure Files, you can access files just like you would with a local file system—either via REST APIs or the SMB protocol.

Key Features

1. SMB Protocol Support: Supports SMB 2.1 and SMB 3.0, enabling seamless integration with on-premises and cloud-based Windows environments.
2. Scalability: Easily scales to accommodate individual files or terabytes of data.
3. Integration: Integrates natively with Azure Virtual Machines and other Azure services, simplifying the development of distributed applications.
4. Security: Secures access using Azure Active Directory (Azure AD) authentication and role-based access control (RBAC).

Common Use Cases

Now that we’ve covered the fundamentals of Azure Files, let’s explore several typical real-world scenarios:

1. Application Configuration and Log Storage

Imagine a set of microservices deployed across multiple Azure Virtual Machines, each requiring shared access to configuration files and centralized log storage. Azure Files lets you create a shared folder where all microservices can write logs and read configuration files—eliminating duplication and ensuring consistency.

Code Example

# Create a storage account using Azure CLI
az storage account create --name mystorageaccount --resource-group myResourceGroup --location eastus --sku Standard_LRS

# Create a file share
az storage share create --name myfileshare --account-name mystorageaccount

# Upload a file to the share
az storage file upload --share-name myfileshare --source /path/to/local/file.txt --account-name mystorageaccount

2. Data Migration and Cross-Team Sharing

Enterprises frequently need to migrate data from on-premises infrastructure to the cloud—or share datasets across departments. Azure Files provides a straightforward way to upload local files directly to Azure and make them accessible to applications or services across your organization.

Data Migration Example

To migrate an entire local directory to Azure Files, use the following command:

# Upload an entire local folder to the file share
az storage file upload-batch --destination myfileshare --source /path/to/local/folder --account-name mystorageaccount

3. Backup and Recovery Solutions

While this article focuses on Azure Files itself, it naturally leads into the next topic: leveraging Azure Files as part of a robust backup and recovery strategy. To protect critical data, you can schedule regular backups from Azure Blob Storage—or other data sources—into Azure Files, enabling rapid restoration when needed.

Accessing Azure Files

There are multiple ways to access Azure Files. The most common method is mapping it as a network drive on Windows. Below is a quick guide to mounting an Azure Files share as a network drive on a local Windows machine.

Mapping an Azure File Share as a Network Drive on Windows

Run the following command in Command Prompt or PowerShell:

net use Z: \\mystorageaccount.file.core.windows.net\myfileshare /u:mystorageaccount mystoragekey

Where:

• Z: is the drive letter assigned to the mapped network drive.
• mystorageaccount is the name of your storage account.
• myfileshare is the name of your file share.
• mystoragekey is the storage account access key (obtained from the Azure portal or CLI).

Once mounted, the file share appears in File Explorer—you can read from and write to it just like any local drive.

Conclusion

Azure Files delivers a flexible, scalable, and secure file-sharing solution that integrates effortlessly with existing Azure services and applications. Whether managing application configurations, enabling enterprise-wide data sharing, or supporting backup workflows, Azure Files offers a reliable and production-ready foundation.

In the next article, we’ll explore how to implement comprehensive backup and recovery solutions for data stored in Azure Files—ensuring business continuity and long-term data protection.
