The first part is JSON. - parses the form. - parses the JSON. - depending upon the JSON accepts/rejects the POST. - for accepted POSTs, writes the three parts as three separate files to S3. It runs behind nginx + uwsgi, using the Falcon framework. For parsing the form I use streaming-form-data which is cython accelerated. (Falcon is also cython accelerated.) I tested various deployment options. cpython, pypy, threads, gevent. Concurrency was more important than latency (within reason). I ended up with the best performance (measured as highest RPS while remaining within tolerable latency) using cpython+gevent. It's been a while since I benchmarked and I'm typing this up from memory, so I don't have any numbers to add to this comment.
