The Secret to Uploading Massive Files to S3 in .NET

Summary

The transcript discusses the technical process of implementing multipart uploads to Amazon S3 using a .NET API, which requires three distinct API endpoints: an initial upload start endpoint to generate an upload ID, a pre-signed URL endpoint for uploading file parts, and a completion endpoint to finalize the multipart upload. The process involves breaking large files into chunks, obtaining pre-signed URLs for each part, and tracking upload IDs and e-tags throughout the transfer. The key practical takeaway is understanding the step-by-step approach to efficiently and securely uploading large files to Amazon S3 through a structured, multi-stage API workflow.
