The Hitchhikers Guide to PHP Load Balancing
Comments (5)
There was once a time when running a big (or popular) web application meant running a big web server. As your application attracted more users you would add more memory and processors to your server.
Today, the ‘one huge server’ paradigm has been replaced with the idea of having a large number of smaller servers which employ one or more methods of balancing the load (known as ‘load balancing’) across the entire group (known as a ‘farm’ or ‘cluster’). This is partly down to the fall in hardware prices which made this approach more viable.
