ShareSafely - File Share Web App (Implement and manage storage

Create a web application where users can securely upload files to Azure Blob Storage. Once uploaded, the application generates a unique, time-limited link for the user to share. This ensures that only authorized users with the link can access the uploaded file for a specified duration.

  • Programming required?: ✅ (For creating the web application and generating unique time-limited links.)

  • Azure Services Used:

    • Azure Blob Storage
    • Azure Web Apps
    • Azure KeyVault

  • Steps:

    1. Storage Setup:

      • Set up an Azure Blob Storage account and create a container to store the uploaded files.
      • Configure appropriate security settings, ensuring data at rest encryption is enabled.

    2. Web Application Deployment:

      • Develop a web application that allows users to upload files. This can be done using preferred frameworks (like ASP.NET Core, Node.js, etc.).
      • Deploy the application to Azure Web Apps.

    3. File Upload Logic:

      • In the web application, integrate Azure Blob Storage SDKs/APIs to facilitate the file upload process directly to Blob Storage.

    4. Unique Link Generation:

      • When a file is uploaded, use Azure Storage SDK to generate a unique, time-limited link for the user.

    5. Secure Credentials:

      • Store any sensitive credentials or configuration strings (like Blob Storage access keys) securely in Azure Key Vault.
      • Integrate Azure Key Vault with the web application to retrieve these credentials when needed.

    6. Monitoring and Cleanup:

      • Set up monitoring to track file upload/download activities.
      • Use Azure Functions or Logic Apps to periodically clean up expired files from both Azure Blob Storage and the Azure SQL Database.
