Blogging Roller: The discredited topology.

The discredited topology.

Jason Carreira: Scaling doesn't have anything to do with whether your objects are remote. How often do you really have one web request cross JVM boundaries? The whole Servlet-tier and Business Object tier topography has been pretty well discredited. It doesn't scale to have to make remote calls.

I would say as soon as you have multiple server clustering.. any other time it's silly at best.

No, that's my point. Why does clustering mean you have to call between servers for a request? Why can't a single request be handled by one server in the cluster?

Given this situation: One large site with 10+ apache/tomcat servers and a couple ejb servers.. 80% of the users never actually reach the relatively expensive ejb servers.. site more balanced, traffic better distributed,transactions protected.
