Throughout this book, there are a number of simple and self-contained code and configuration examples. To successfully run these, we can easily make use of the Ubuntu powered desktop (https://www.ubuntu.com/desktop) and server (https://www.ubuntu.com/server) machines. Those of you using Windows or OSX machines can easily install Ubuntu within a VirtualBox. Installation instructions for VirtualBox can be found on the official VirtualBox page (https://www.virtualbox.org/).
