This document discusses the challenges of building a new Joomla! demo/free platform. It outlines the goals of demo.joomla.org versus joomla.com and how demo.joomla.org provides real hosting environments without limits while joomla.com has some limits and no access to hosting. It then describes how the platform provisions accounts super fast using pre-provisioned accounts, dynamic DNS updates, and an auto login system. Finally, it discusses how the platform uses resources efficiently through techniques like Varnish caching, Linux containers, unique storage, and a lightweight Joomla setup.
