Upgrading instance is just a few clicks for a cloud server, like EC2 and Azure, but what are the configuration change necessary to harness the extra power?
While I think this can as well be a general question, my specific configuration is like:
HAproxy, Varnish, PHP-memcached-MySQL on a centos Linux with Azure
I have seen people doing load balancing with domain like 192.xxx.xxx.1, 192.xxx.xxx.2, I suppose that is about setting another different machine/instance right? Or does it make sense to make servers on different ports and do the load balancing? (Sorry I am really new to these things)
Another thing I can think of is memory limit in PHP. I would really hope to hear for people who have managed great networks. Thanks a lot!
