JBoss Fuse
JBoss Fuse which includes Fuse Fabric can manage and provision containers in a cluster / cloud / etc.
JBoss Fuse uses Karaf as the container. So what you can do with Karaf you can do as well with JBoss Fuse.
On top of that Fuse Fabric brings to the table, all the cluster provisioning and management. And with a distributed registry for HA et all.
With JBoss Fuse you can deploy and manage your Camel routes in a cluster. And perform rolling upgrades / downgrades across the nodes in the cluster, and much more. And to go along with that you have commands in the Karaf Shell to perform actions, and as well a web console UI based on http://hawt.io/.
Short answer: Yes JBoss Fuse can manage and provision your Camel routes in a cluster.
SwitchYard
In terms of JBoss SwitchYard, then it uses JBoss Application Server / WildFly as its container (at this time of writing SY does not yet support OSGi). So SY leverages the clustering and management support from JBoss Application Server.
