** "Scaling File Operations with Presigned URLs: A Secure and Efficient Solution" As modern web applications continue to grow, handling file operations efficiently and securely becomes increasingly important. Traditional file handling approaches can strain server resources and impact performance, but Presigned URLs offer a powerful solution that combines security, scalability, and performance. Presigned URLs are temporary, secure URLs that provide controlled access to resources in cloud storage services like Amazon S3 or Google Cloud Storage. These URLs encapsulate authentication information and permissions within the URL itself, allowing direct access to resources without requiring separate authentication credentials. This approach has been implemented by developers using Python, Flask, and AWS S3, demonstrating its efficiency and security benefits. Presigned URLs can be used in various scenarios, such as distributing large software packages, secure document storage and retrieval, and secure distribution of marketing materials. ** Source: https://dev.to/lionel_etaba/beyond-traditional-file-uploads-scaling-with-presigned-urls-4jid
