Introduction to Azure Files

Azure Files offers the industry's first fully managed cloud file share that is accessible via the industry-standard Server Message Block (SMB) protocol and Network File System (NFS) protocol. This means you can "lift and shift" legacy applications that rely on file shares to Azure. Azure Files can be mounted concurrently by cloud or on-premises Windows, macOS, and Linux deployments.

Key Features and Benefits

• Fully Managed: Azure manages the underlying hardware infrastructure, eliminating the need for you to deploy and manage your own file servers.
• SMB and NFS Support: Provides compatibility with a wide range of operating systems and applications.
• Cloud Native: Built for the cloud, offering high availability and durability.
• Scalable: Easily scales to meet your storage needs.
• Secure: Supports encryption in transit and at rest.
• Hybrid Integration: Seamlessly integrates with on-premises environments using Azure File Sync.

Common Use Cases

Azure Files is ideal for a variety of scenarios, including:

• Lift-and-shift applications: Migrate applications that require file shares without re-architecting them.
• Shared configuration files: Centralize application settings and configurations.
• Development and testing: Provide shared storage for development teams and testing environments.
• Log files: Store application and system logs centrally.
• Container storage: Use Azure Files as persistent storage for containerized applications.

Azure Files Tiers

Azure Files offers different performance tiers to meet your specific needs:

• Standard: Cost-effective, suitable for general-purpose workloads.
• Premium: High-performance, low-latency SSD-based storage for demanding workloads.

Getting Started

To get started with Azure Files, you'll need an Azure subscription. You can create an Azure storage account, and then create a file share within that storage account. You can then mount the file share to your clients using SMB or NFS.

Example: Creating and Mounting an Azure File Share (SMB)

Here's a simplified overview of creating and mounting an Azure File share:

1. Create a Storage Account: In the Azure portal, create a new Storage Account.
2. Create a File Share: Within your storage account, navigate to "File shares" and create a new share.
3. Get Connection String: From the file share's overview page, you can get the connection string and storage account key.
4. Mount the Share:
   • Windows: Use the net use command:
     net use Z: \\storageaccountname.file.core.windows.net\sharename /u:AZURE\storageaccountname storageaccountkey
   • Linux: Use the mount command:
     sudo mount -t cifs //storageaccountname.file.core.windows.net/sharename /mnt/share -o vers=3.0,username=storageaccountname,password=storageaccountkey,dir_mode=0777,file_mode=0777,serverino
   • macOS: Use Finder's "Connect to Server" option.
