Pylons is a modern web framework that was written in the Python programming language and follows the model-view-controller design pattern. The framework significantly facilitates the creation of complex web applications. Pylons makes extensive use of the Web Server Gateway Interface, which is an interface between web servers and web frameworks for the Python programming language. This makes it possible to outsource functionality to separate modules. Pylons is heavily influenced by Ruby on Rails.

Squid is a free implementation of a proxy server that also caches contents, which provides a benefit in terms of speed. As a result, an upstream Squid is often used to accelerate web servers.
A practical example of the successful use of Squid is the free encyclopedia Wikipedia. The fact that the Squid proxy holds websites in memory means that they can be directly delivered, which relieves the burden on database systems and web servers enormously.
In addition, Squid allows the filtering of network traffic with the assistance of additional software, such as DansGuardian.
Squid is compatible with Linux, Solaris, various BSD derivatives, and Microsoft Windows.
Squid is free software, and the source code is available on the project page .
Apache Tomcat is an application server that can run Java code on web servers. Tomcat already contains a HTTP server, but in live operation an upstream Apache web server is generally used. It is written in the Java programming language and its use is therefore largely platform-independent.

The Apache HTTP server is a free web server. Apache is one of the world’s most commonly used web servers. The software is developed with the help of a large team of volunteers, under the auspices of the Apache Software Foundation. Its modular design means that it can flexibly adapt to specific needs. It is possible to dynamically create websites, which can be achieved via SSI (server side includes) or by the use of script languages, such as PHP, Perl, or Ruby. The ability to use script languages is ensured either by the integration of modules or via the CGI (common gateway interface). Apache is compatible with a range of different operating systems, including Unix, Linux, Windows, and Novell NetWare.

Django is a web framework that was written in the Python programming language and follows the model-view-controller design pattern. Django is the counterpart to Ruby on Rails in the Python world. The software enables convenient and sustainable management of websites.

HAProxy is an Open Source proxy application for TCP and HTTP-based applications, and also provides a highly available load balancer.
The project, published by Willy Tarreau on December 16, 2001, has made a name for itself with its fast and efficient operation.
The frequent integration of HAProxy in enterprise-like infrastructures is making the issue of monitoring increasingly important in this respect.
Various applications offer associated solutions, such as HATop, an Open Source application, or Datadog, the commercial counterpart.
nginx is a powerful web server and reverse proxy server.
It is characterized by its simple configuration and low resource consumption.
Originally developed for a Russian search engine, it is becoming increasingly popular worldwide.
