On the CloudWays blog they've posted a tutorial that introduces you to the Silex framework, a product from SensioLabs of Symfony fame and using it on a cloud hosting platform (their own).

Extensibility is one of the main aims of web app development projects. However, there are times when you need to get things up and running as soon as possible and with minimum time dedicated to coding. This is where micro-framework s really outshine the competition. There is a long list of these frameworks including Silex, Slim, Lumen, etc. These are ideal for developing small-scale applications with clean code and user defined directory structures.

In this tutorial I am going to explain how to install Silex, its operation, directory structure, Routings and HTTP Requests. Silex is a micro-framework written in Symfony and inspired by Sinatra, a DSL for quickly creating web applications in Ruby with minimal effort.

They start by helping you get the CloudWays instance up and running with their "PHPStack" setup. Once created they show how to get to a command prompt, make the public HTML directory and use Composer to install Silex and Twig (for templating). The tutorial then briefly covers the directory structure for the site and the code to create the Silex application instance. They define some of the basic routing (to work with book data) and show the handling for sending feedback submitted via a simple page. The remainder of the tutorial shows the use of different features of Silex including: providers, middleware, before/after handlers and defining controllers as classes.
