Is it recommended to run 2 application servers on a single machine?

hello,
one of our projects requires 2 application servers, macromedia coldfusion mx server and sybase enterprise server. our clients are asking us to install both servers on the same machine. i personally doubt this will be okay! if this is not recommended, please tell me why and provide me with some information so i can convince our clients to have the better solution which is - in my opinion - one application on one machine ... please advise

thanks

It should be okay, as long as you configure each application to run on different ports.

ColdFusion server is a scripting language that links into the webserver API. It doesn't do any of the page serving at all so ports dont matter to it. Sybase shouldn't care that CF is installed and shouldnt notice. As CF only parses documents with the .cfm extension it shouldnt interfere.

Question basically sums up to is it ok to run httpd and db on one box? And the answer is - in most cases yes. However, if your site is using databases heavily then you might want to consider getting a separate more powerful server strictly for db on it and then split your httpd into several boxes and have them feed off on database box in the backend. But that's for more resource hungry sites - most people will do just fine with having both httpd and db on one box.
