Hey all! Let me clarify a few of the terms here and describe a bit how Django operates in this context.
"Serverless" in this contexts means "without any permanent infrastructure". The server is created _after_ the request comes in, and it dies once the response is returned. The means that we never have to worry about server operations or horizontal scalability, and we pay far, far far less of a cost, as we only pay for server time by the millisecond. It's also radically easier to deploy - a single 'python manage.py deploy production' gives you an infinitely scalable, zero-maintenance app. Basically, Zappa is what comes after Heroku. To do this, we use two services - Amazon Lambda and Amazon API Gateway. The first, AWS Lamdba - allows us to define any arbitrary function, which Amazon will then cache to memory and execute in response to any AWS system event (S3 uploads, Emails, SQS events, etc.) This was designed for small functions, but I've been able to squeeze all of Django into it. The other piece, API Gateway, allows us to turn HTTP requests into AWS events - in this case our Lambda context. This requires using a nasty language called 'VTL', but you don't need to worry about this. Zappa converts this API Gateway request into a 'normal' Python WSGI request, feeds it to Django, gets the response back, and performs some magic on it that lets it get back out through API Gateway. You can see my slides about this here: http://jsbin.com/movecayuba/1/edit?output and a screencast here: https://www.youtube.com/watch?v=plUrbPN0xc8 Now, this comes with a cost, but that's the trade off. The flip side is that it also means we need to call Django's 'setup()' method every time. All of this currently takes about ~150ms - the majority of which is spent setting up the apps. If we could do that in parallel, this would greatly increase the performance of every django-zappa request.
