Best solution for real time server replication .
Sorry if my English is not well .
I read this tutorial https://www.digitalocean.com/community/tutorial_series/load-balancing-wordpress-with-haproxy about setup load balancer . but i have a question .
what will happen if i upload an image to wordpress or install new plugin ?
both servers will update automatically ? i guess the answer is no .
so how can i setup a real time server replication ?
