title: Scaling from one server to multiple servers
body: <p>Lets assume I'm running two servers: one for the website and the other for the DB.<br>
  Obviously, there will be a point when a bottleneck would occur for both servers.  </p>
  
  <ul>
  <li>What should one need to do at this point? are there any best practices?</li>
  <li>What are the advantages of using cloud cloud services like AppEngine, Appfog etc? </li>
  </ul>
  
  <p>I'm newbie at this zone so please be patient :)</p>
