Azure File Share is a robust cloud-based storage service that enables organizations to store and share files seamlessly. In addition to its native capabilities, Azure File Share allows for granting access to on-premises users, ensuring a smooth transition to the cloud while maintaining collaboration with existing users.
To utilize Azure File Share from an on-premises environment, the following essential configurations are required for a seamless integration:
1.Establish a Robust Networking Setup:
- Deploy a domain controller on Azure and configure the DNS settings to point to Azure DNS for seamless name resolution.
- Create a secure VPN tunnel between the on-premises site and Azure, ensuring a protected and encrypted connection.
2. Enable Proper DNS Resolution:
- On the on-premises network, set up a conditional forwarder for the “file.core.windows.net” domain, directing it to the Azure domain controller. This ensures efficient name resolution for Azure File Share.
3. Implement Secure Network Access:
- Open the SMB port 445 on the on-premises network security group (NSG), allowing access only from the VPN tunnel to the Azure Virtual Network (VNet). This ensures that the communication between on-premises and Azure is securely restricted.
4. Set Up Azure Storage Account:
- Create a dedicated storage account on Azure to host the Azure File Share. This account serves as the storage container for your files and provides the necessary infrastructure for the file share.
5. Establish NTFS Permissions and Security Groups:
- On the on-premises side, create a security group to manage NTFS permissions for file access. Synchronize these groups to Azure Active Directory (AD) for unified management.
- Map the on-premises security groups to the corresponding Azure Identity and Access Management (IAM) groups, ensuring consistent access control across the environment.
By following these configurations, you can seamlessly leverage Azure File Share from your on-premises environment, allowing secure and efficient file sharing capabilities.
