Django, Flask or FastAPI, ASGI-WSGI, asynchronous-synchronous, protocol or web server, workers or threads, gunicorn-uvicorn - What is going on!? What exactly are these? How do they come along together? Do I even need to know about them?
Developing back-ends for dynamic websites can be done in a lot of different ways, and fortunately, python has a great set of libraries and packages to help us with the implementation. The problem arises when we dive deep and are overwhelmed with the stuff we have at our disposal.
During this talk, we'll try to find answers to the above questions. We'll take a look at the high-level and core features of different parts and understand how they are kept compatible with each other to bring out a fantastic web ecosystem.
Who's this talk for?
- Anyone who wants to start their web-development journey in Python (or who has started with Flask or Django, and want to explore more).
- People who're wondering what's this "WSGI" thing coming up, time and again at different places.
- People who want to understand the role of gunicorn or uWSGI, which they read about in the deployment docs.
- Anyone who wants a smooth transition into asynchronous python web ecosystem.
- Anyone who's overwhelmed with terminologies like the ones stated in the first line of Description.
- Anyone who isn't really sure how the data flows through the different layers of libraries and reach the URL-dispatcher in their favourite framework.
Talk Objective
The motive is to make the web-developers aware of the different parts of the python web ecosystem so that when they face them either while resolving a bug and reading logs or when they are going for tweaks to improve performance - they'd know in which part they'll have to look out for.

Vibhu is a student, a pythonista and an open-source enthusiast. He likes to play around with web servers and sometimes, clients. On weekends, you can find him in one or the other meet-ups or conferences, discussing about snakes and unicorns or other tech stuff, mostly in local tech-groups like PyDelhi or Django-London. Past conferences where he's given talks include PyCon India'20 and PyCon Sweden'20.
