Is there some good article on scalling out LAMP. For example what are the equivalent tactics to these Windows tricks: 1. Web Server Scalling out: Just add another Windows NLB node , provided all Webservers store all data on a separate place like SQL Server. Do you do linux NLB thing in this case ? 2. SQL / MYsql database. Lets say you have a site using one of the popular OpenSource frameworks like Wordpress. Wordpress has uses a bunch of Mysql databases. Your site has grown so much and now MYSQL is the bottleneck. What would you have to be doing in such scenario. I.e have a Wordpress developer /engineer rewrite or mod the framework's architecture ?
