The automaton architecture is described by the following picture. The web site and the automaton are connected via a mysql database. Each part can be placed on different servers. The automaton part is an application coded with C++. The web site is coded with PHP. This one is a minimal example which can be replaced.
The automaton works on Linux Ubuntu (www.ubuntu.org).
