Load balancing large-scale PHP
<p>So, I am trying to figure out how to design my server infrastructure to handle large amounts of traffic. </p>

<p>I am considering load balancing, but I need to figure out how to scale.</p>

<ul>
<li>How to separate servers? Basically how to design the server architecture?</li>
<li>What are the issues with having multiple servers?</li>
<li>What is there to consider when scaling with PHP?</li>
<li>What are the issues with load balancing?</li>
</ul>

<p>Basically I want to learn from other people's mistakes/experiences. Does anyone have any good books/tutorials to help get me started? Thanks!</p>
