Answer 1

Do as you like) All the salt will be next!
At the start, without a big load, it’s more convenient (and cheaper) all in one.
And then, if the application "tramples", you will have to think about scaling .
PS - But if you immediately know that the project will "trample", then
you need to think about scaling right away!
