Hey, I’m hoping someone can help me out. I’m having difficulty understanding some basic principles of load balancing multiple web servers. Basically I don’t know how you would edit a load balanced WordPress site or Web app.
Using your topology of 3 web servers with Galera cluster database nodes and a DNS load balancer like cloudflare, how would you make significant changes to the site?
Even if you use media storage and database offloading, when you update a plugin or change something significant you will have different sites depending on how DNS routes you.
I’ve read elsewhere some opinions on this, but am not sure. Do I basically use images/snaps of the servers to edit the site, then copy those and route to load balancer? Then decommission the old web servers?
