[PyCon AU 2021] Hey, Python-Web-Community! What's going on?

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.
