The document discusses the past, present, and future architecture of EDD WorkshopEZTABLE. In the past, the architecture consisted of PHP workers and a PHP/JavaScript frontend. Currently, the architecture is similar but includes apps and uses a hairball for communication. Going forward, the architecture will move to app facades running on different platforms like Node.js, Go and Lua, with workers and a RESTful API for communication between components.
