Which installation method used for this forum?
What sort of OS do you host on? Have preferences for a webserver?
The install guide is quite comprehensive - https://docs.nodebb.org/en/latest/
FYI - I am on a centos 7 based instance, with Nginx as the SSL front end / proxy and multiple nodebb instances for different sites. The backend is redis + mongodb. About as complicated as it can get. 
@shri I'm asking about what installation method was used for setup of community.nodebb.org?
And regarding databases you mentioned, I thought it can be one either, but you wrote using both at the same time?! 
Apologies! I thought you meant "this forum" as in "this forum software" and not specifically the site.
My build is complicated as I wanted to test scalability.
Some info about my specific build (and why redis+mongo) can be found here - https://community.nodebb.org/topic/5920/scaling-nodebb-on-google-cloud-is-this-approach-correct/3
This forum is hosted on DigitalOcean, and follows our guide
@julian I assume, you mean Ubuntu based install guide.
There did appear to be a guide in the docs on how to install a nodeBB installation on DigitalOcean (a VPS provider), but the link is now broken (or at least for me it is).
I'm not part of the nodeBB team, but yes, it does look like they are running their installation from an ubuntu build. This could be from within a Docker container, so their server architecture could actually be completely different. It's all down to preference though.

@askar Yes, Ubuntu, precisely 
@Joel-Murphy We don't use Docker, actually. I went for LXC instead for our hosted services, and our community forum is a custom install (as we didn't have hosted services when we started this forum).
We really ought to transition it over to our SaaS services. Where do I send the bill?

And where will users find you if, god forbid something goes down? All eggs one basket and all that...
