How to install NC & Online office on same server

Hi every one.
I have successfully installed and configured NC & Online office on different system.
But now we planed to give NC to production so i want to know how to install & configure on same server.
And another one we have around 150 users in our company. They all access this NC server and edit same Excel docs i.e Collaborative Editing. Which server configuration suitable for us.?

It depends on your usage of Nextcloud and the performance of the server it is installed on. A single high-spec server should be sufficient, but two lower-spec servers could offer more reliability. See below:
