It isn't really a significant step. You just plug in another web server and make sure the load balancer and DNS settings are right.

- staunch 19y agoYes in theory you're correct. In practice things are usually dirtier. What if they don't have a load balancer? What if they want redundant load blancers? What if they use round-robin DNS and then need a failover procedure? What if round-robin DNS isn't balanced enough for them? What if logs files need to be merged? What if the web servers aren't 100% identical? Data needs to be sync'd? Load distributed more intelligently? Cron jobs modified? etc, etc. Perhaps they kept things unusually clean and simple, but most sites require a little finagling when they go to multiple web servers. I'm not saying it's difficult, but I do think it's wise to expect a few bumps.
