I have a scenario where an application requires multiple private IP addresses but does not require the resources of multiple instances.
In this case, I would like to run multiple jboss instances on the same EC2 instance without port mangling.
I've seem threads up to 2009 that stated this is not possible, checking if this has changed.
EDIT: I want to re-emphasize the private IP address is the question, not the elastic/public IP address. I am sorry I did not make this more specific.
