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.
