Discourse + web server. Possible or better to avoid?

Is this a recommendation to switch to Nginx then? I have absolutely no experience with it and any web server I’ve ever used, preconfigured included, has used Apache.

However, there appears to be a large number of issues getting it to work properly, particularly with SSL.

Would it be simpler to run two droplets, one for the website and one specifically for Discourse? I suppose I could just change the DNS record for the subdomain to point to the Discourse droplet and that should resolve the issue. Just find it odd to run two servers for a forum.
