title: Memcached: Where to put?
body: <p>For Drupal Stack, i have 3 Servers: </p>
  
  <ul>
  <li>Varnish</li>
  <li>Web Server</li>
  <li>Database Server</li>
  </ul>
  
  <p>.. and <strong><em>let's say i ONLY have this 3 Servers limitation. No more server</em></strong>.</p>
  
  <p>Now i have to install <code>Memcached</code> but i'm not sure where to install it.<br />
  So the <code>Memcached</code> for the Drupal Stack:</p>
  
  <ul>
  <li>Where to put at? (Instead of talking about an another separate box.)</li>
  </ul>
  
  <p>Honestly, as i found <code>Drupal Memcached Module</code>, then i though <code>Memcached</code> is meant for Application Server where the Drupal is sitting at. So i have put it on the Web/Application Server but it seems the result is even worse then before. So where? At Database Server? Or, on all?</p>
