title: Magento on Amazon ec2 and var /common files directory
body: <p>I want to put on EC2 a medium Magento Installation.</p>
  
  <p>I have used a Load Balancer, CDN for images, RDS mysql.</p>
  
  <p>But now I have to choose where and how save Magento files( <code>/app</code> and <code>/var</code> directory).</p>
  
  <p>I Think that use the local EBS file system is better, and with GIT I don't have any problem to update the code. But i have a problem with the <code>/var</code> directory, in this I have a directory with many csv used for some integration with other system (that read it with an FTP).</p>
  
  <p>How I can manage those files?</p>
