can iPad run frontend and backend

Let's say one builds an iPad app with the following requirements:

• multiple iPads must be able to have the same state,
• one of the iPads will always be unused by humans and simply connected to a large screen
• Some basic data must be stored for export later,
• iPads may be on the same network

Of course, most developers would use the cloud as the backend location but I p am thinking that one could possibly run the backend web server on the iPad connected to a screen. So, this iPad would be running two things: the app and the web server app. Is this possible? Assume the load is very light.
