Question on Deployment - Part 2

[Krishna Jonnalagadda]

What could be the reasons to use a webserver (in a differnet physical server : WEBHost) if all we have is a xyz.ear file and application uses all local ejb's. I know that the xyz.ear file can be deployed in an application server (in a differnet physical server: APPHost), but wanted to know if having a webserver in a different physical server gives any advantage ?

Thanks

Some times web servers reside on seperate box. a) If it is also serving static content b) if it is to be placed in a dmz

Thanks for your reply ...

But my question was do we need the web server at all ? If the application runs in one JVM with no remote calls, i think an application server : APPHOST is sufficient where we can deploy the xyz.ear file. At the same time i feel that having the static content in a seperate web server: WEBHOST will improve the performance. I'd like to know if there are any other advantages in this scenario and is it worth to have a webserver just for static content ?

I also thought the same way, but, What if you need to display any important outage messages (static page) if the whole appserver cluster is not available?
