Nice work. I have several web apps that run on EC2 instances, that have my users uploading via Browser -> EC2 -> S3. This can cause high latency on some of my smaller EC2 boxes, which is annoying, it else forces Elastic Beanstalk to spool up more instances unnecessarily when it thinks traffic is being flooded when large files are being uploaded. I've always wondered about the best strategy to go 'serverless' with the file uploads and have the user's browser essentially upload direct to S3, and this tutorial gives a great insight into that - thanks.
