Am I the only one that's never heard of this before? The Oracle JRockit team is looking at eliminating the OS from the stack required to run Java. This product will be called JRockit VE (not out yet)
Virtualization is rampant with the customers I work with, and in many cases there's no need for a host OS any more. Since the JVM is just another virtual machine, it makes sense in a lot of ways to eliminate the host OS from that stack too.
Oracle won't release this separately, but instead it will underpin Weblogic Server Virtual Edition.
From my notes:
- Will only be available in virtualized environment, and only headless virtualized environments
- Only runs a single Java application
- Expected in CY 2010
- Typical overhead from Linux VM is 1 GB -- overhead from JRockit VE is 2.5 MB
- Supports offline configuration and patching -- not possible with Linux today
This ties in nicely with the appliance push that Oracle is making, by eliminating the host OS building appliances should be quite simpler.
Where do I get my beta copy?
