What does the term distributed hypermedia system mean?

Question

Computer networks

When trying to learn the concept of REST architecture, the term distributed application scared me. Since I have not studied networks, I would like to get an understanding from connoisseurs of what this means.
What is a distributed application on a network or a distributed hypermedia system?

Answer 1

There are several backend servers with your rest api.
There is one entry point with a balancer that can redirect the user's request to one of the servers.
Here it is distributed. The more users, the more servers you can run to keep them going.
The backend must be written taking into account that it can work in multiple instances (for example, there should be no conflict when working with the database)
