GFv2 has clustering built-in with multiple JVMs/instances. (HTTP) load-
balancing can be yours or the one provided with web server plugins.
Alternatively you can look into Terracotta (their latest version
should support GlassFish) which has a different approach which may be
closer to what you're asking for (although it would be interesting to
understand your use-case better).
