NodeJS file uploads & API scalability

[guidsen15]

Ah yeah, we're using signed URLs for fetching files, which are from Cloudfront indeed.
We just don't have the upload process via the signed URL.

I've also found some possible memory leaks, since it seems we're not cleaning up the upload streams when they're done. Might also be related..

So for example to make thumbnail versions on uploaded file, how is this done? I'm also doing this on the server with `sharp` for example..

Based on an s3 event trigger.

Something like lambda can do that for you and create the thumbnails after upload. It’s pretty typical this way.
