Response to: Performance NOT EQUALS to Scalable
Amazon does not have a J2EE architecture. They use custom C++ stuff and Perl. The point of the article is that PHP can scale to handle large sites as well as Java can. The fact that an HTTP load-balancer is separate from PHP looks like a positive thing to many people. Fail-over is typically provided by the load-balancer as well, assuming you are using one of the many approaches for sharing session data with PHP.

  No doubt that parts of Amazon still run on Perl but I think they have mentioned several times on conferences that Perl was a dead end for them and that they switched to Java for all new development.
  
  Most, if not all, of their public web services are also written in Java.
