So, let's say I have this massive content-heavy site with all sorts of paths like mysite.org/category/date/slug or mysite.org/someterm/subterm/date/slug. Let's say all this content is in English, and now I've gotten my hands on a Spanish version of all of my content. How feasible is it to integrate the Spanish content into the site, using the same installation, but only having the site show up in Spanish when people go to es.mysite.org, es.mysite.org/category, or es.mysite.org/someterm/subterm/date/slug.
How scalable is Drupal 8 in this regard? If we want to have several different language sites, potentially with different templates, would it be best to use different installations of Drupal 8 or does it facilitate this kind of set up I explained above so that one installation is perfectly logical?
