Routing: Apache httpd

Introduction #

The Apache httpd server is one of the most widely used web servers. There are modules that adapt the server to different usage scenarios. In the example, modules are configured that turn Apache httpd into a reverse proxy.

Reverse proxy #

While a conventional proxy can be used to process traffic from a network to the outside, a reverse proxy is a solution for inbound network connections.

It can forward external requests to specific services. This means that the entire microservices system can be accessible under one URL but can use different microservices internally.

The concept of a reverse proxy has already been explained in the lesson, Router: Zuul.
