I need to understand some steps so I try to ask here. I have configured a lemp node with Wordpress installation. I then decided to add a horizontal node at the APP level and a Redis node for the object cache (as well as obviously a load balancer which is necessarily necessary) and I implemented an addon for file synchronization for the / ROOT / folder. wp-content (I followed the configuration suggested by the guides). I state that I have NOT distributed a preconfigured cluster.
So I would have 1 LoadB. + 2 Apps + 1 Redis database at the moment.
- I found that the database in this case is only one for both apps (and it suits me), so I wonder: when the database starts working at full capacity, I can run into problems when you activate or deactivate the second node? What precautions should you have in this case so that everything runs smoothly?
- Does the addition of a second (third, fourth etc) node on a horizontal level (app node) have the function of increasing the cloudlets available in case of need or am I not understanding anything?
Thanks to those who will answer
