What is stored in the webserver? (Separated Database)

by

Assuming a classified website where real estate agents post their houses advertisement for rent or sale

When I built the server, I separated the database and the webserver

Database Server: Ubuntu and MariaDB only

Webserver: Ubuntu, Nginx, PHP, Redis, WordPress

I have been wondering all the time what is actually being stored in webserver.

Say, if I destroy the webserver and create a new set of webserver (of course complete with all the same WordPress plugin + theme), what do I lose?

I think I will only lose the house images that are uploaded by the house agents?

Also, is there any guide to do set up load balancer? Couldn’t find a good one so far.

Thanks heaps

The WP database contains everything that is related to content: posts, pages, theme settings, plugin settings, media of all kinds. So if you were to replace the WP database with a brand-new WP database, all of your content – and many of your settings – will be gone.

The WP ‘code’ (PHP, CSS, JS source files) is stored in the wp-xxxxx folders, plus the site root. Some CSS might be stored in the WP database, but the ‘core’ code is in the site root and the wp-xxxxx folders.

Can’t speak to load balancing…perhaps someone else will chime in on that.
