Azure Files is a fully managed cloud file share service from Microsoft Azure that provides hosted SMB and NFS file shares accessible from cloud and on-premises clients using standard file system protocols and the FileREST HTTPS API. It supports identity-based authentication via Active Directory and Microsoft Entra ID, snapshots, soft delete, and Azure File Sync for hybrid scenarios. The FileREST data-plane API uses shared key, shared access signatures (SAS), or Microsoft Entra ID OAuth 2.0 bearer tokens for authentication, while the control plane uses Azure Resource Manager.
