What about dedicated servers?

[ghost]

I am not an expert in this, but I kinda understand what I need and what rely on, for example - Roblox servers. If project uses such technology by adding an extension I guess, then a dedicated server is created (maybe it's called container-like?) that not only transfers data to clients like the usual wss does (сorrect me if I don't know something), but also processes it - movement of NPCs as an example. Is it possible?
