In this recipe, we will learn how to deploy a Flask application with Apache, which is, arguably, the most popular HTTP server. For Python web applications, we will use mod_wsgi, which implements a simple Apache module that can host any Python applications that support the WSGI interface.

Note

We will start with the catalog application from the previous chapter. There is no need to make any changes to the existing code.
