The following video demonstrated the integrated capabilities of the Zend Platform: http://www.zend.com/support/user_docs/ZendPlatform/video/demo/index.php.
Granted that this is a commercial, one has to still admit that - THIS IS IMPRESSIVE!
Let\’s be honest - this is one very cool integrated, intelligent system. The problem detection/debugging system looked absolutely awesome. Not many, even Java, platforms have cool system like that and - yes, it is a life-saver.
