Web servers

The web server exposes the HTTP port, accepts incoming connections, and redirects them towards the backend. One common option is nginx (https://www.nginx.com/). Another common option is Apache (https://httpd.apache.org/). The web server can directly serve a request, for example, by directly returning static files, permanent redirects, or similar simple requests. If the request requires more computation, it will be directed towards the backend, acting as a reverse proxy.

The primary objective of the web server in the presented architecture is to work as a reverse proxy, accepting HTTP requests, stabilizing the input of data, and queuing the incoming requests.

A basic configuration for nginx could look like this. The code is available on GitHub at https://github.com/PacktPublishing/Python-Architecture-Patterns/blob/main/chapter_06_web_server/nginx_example.conf.

    listen 80 default_server;
    listen [::]:80 default_server;
