Qubes as server OS

What are the options for using Qubes as an OS for a web server?
I was thinking to use several qubes for horizontal app access(just dummy apps), and a DB, caching etc with another machines I have(non-Qubes) on lan.
Did anyone use anything like this? Any tips? Or is it not worth it much?

Just as a practical example, I thought to use my primary machine(kinda high-end hardware, with Qubes, I use it for everyday tasks) with several(around 4-6) small(1vcpu, 1gb ram) qubes for dummy express apps with 1 gateway qube(2vcpu 8gb ram), all that for a better security and isolation, obviously, but I’m not really sure if it’s the right choice and should I really do that.
