Building a Secure and High-Performance File Sharing System for Distributed Corporate Offices Using Azure Files

In today's globalized business environment, organizations with geographically dispersed offices need reliable and secure ways to share files across departments. One such organization requirement is the Finance department’s need to share cost information for auditing and compliance purposes. The file sharing solution must ensure fast access to files, limit access to select virtual networks for security, and provide safeguards such as snapshots for file recovery.

In this article, we'll walk through setting up an Azure Files storage account that caters to the corporate office's needs, including file shares, directory structures, access control using virtual networks, and snapshot capabilities for data recovery.
