Great presentation. The slides explained everything really well and the whole process is a lot clearer to me.

I do have a quick question though. When going with this sort of setup in your production environment, can you use CF Standard or does it have to be enterprise for the multiple instances EAR/WAR deployments?

Thanks

Thanks for the presentation. I would use this setup on a developer or staging-server but never ever on a production enviroment.

D'oh, found out it's enterprise. Thought it was but didn't see it mentioned in your preso.

Managed to get Railo working... kinda... The admin displays fine but it doesn't seem to like multiple virtual hosts like the CF instances do.

@Marc, why wouldn't you ever set up production in this way? Are you against multiple instances for some reason?

@david: yes, multi-server is only in enterprise and developer editions

@marc: we use multiple instances in production at freelibrary.org. multi-server's main purpose is for clustering

what i would caution about is using older versions of CF on newer versions of the Java Virtual Machine (JVM) without thoroughly testing your site for both functionality and load. Older versions of CF are only tested and guaranteed to work up to a certain JVM version, so it is up to you to make sure it works before releasing it to production
