In the early days features like My Dubs, which enable users to upload their Dubs onto our platform, uploads were going directly against our API, which then stored the files in Amazon S3.

We quickly saw that this approach was crumbling our API performance big time. Since users usually have slower internet connections on their phones, the process of uploading the file took up a huge percentage of the processing time on our end, forcing us to spin up way more machines than we actually needed. We since have moved to a multi-way handshake-like upload process that uses signed URLs vendored to the clients upon request so they can upload the files directly to S3. These files are then distributed, cached, and served back to other clients through Amazon CloudFront.
