title: Amazon EC2 - Which Ubuntu server to choose: 32bit or 64bit?
body: <p>I'm in the process of selecting an AMI for my website on the Amazon EC2 network.  It seems like the Ubuntu instances come in either 32 or 64 bit flavors.  Presumably the 64 bit systems give you more memory address space, which is good.  However, I'm wondering if it is a problem finding pre-compiled binaries.  Am I better off sticking with 32 bit?  My web application is not terribly memory intensive.  </p>
  
  <p>Why would I select one over the other and what are the pros and cons?  </p>
