Hi all,
Ioannis Canellos and I have worked and proposed an enhancement to Apache
Karaf named Cellar.
Cellar provides clustering to Karaf by using Hazelcast.
Ioannis blogged about Cellar and also provided a demo video:

As you already know, I'm working on ACE to add full Karaf support.
ACE already provide cloud support by the usage of jclouds.
So we can see ACE:
- as a provisioning platform which deploy bundles/config/features (soon
:)) to a Karaf target. This target could be a single Karaf instance, or
a Karaf cluster running on Cellar. ACE is the provisioning and Cellar is
the sync of nodes states, replication of resources, etc.
- as a provisioning platform to all Karaf cluster nodes. In that case,
Cellar is the sync of nodes but ACE should be able to target all nodes
and replicate node resources.
So, I would like to have your feedback about the role of ACE in this
kind of environment.
My idea is to provide a complete enterprise OSGi platform composed by:
- Apache Archiva as a central EBR/OBR
- Apache ACE to create distribution based on resources
(bundles/config/features) provided by Archiva and provision a set of targets
- Apache Karaf as target runtime/container
- Apache Karaf Cellar (using Hazelcast) to sync Karaf nodes, etc
I would like to write some architectural draft on ACE wiki about that,
so any feedback or resources (slides) are welcome :)
Thanks
Regards
JB
