Asynchronous Network Requests in a Web Application

Explore strategies for implementing asynchronous network requests in web applications during this EuroPython 2016 conference talk. Delve into the challenges of composing responses from multiple services in a Service-Oriented Architecture (SOA) paradigm and learn various solutions to parallelize network calls. Examine the integration of asynchronous techniques with different WSGI web server parallelization models, including running Twisted event loops, using coroutines, and leveraging Asyncio. Gain insights into optimizing performance for Django, Flask, or Pyramid applications running on servers like Gunicorn or uWSGI. Compare synchronous and asynchronous approaches, understanding their impact on scalability and response times in complex web services.
