Using fuse ESB for about 6 months, I'm very happy with it.
Services are easily deployed as OSGi components - these are quite easily configured and deployed as fuse features
. Fuse profiles
then contain property files that define which features
are deployed to your OSGi containers.
Although I haven't used every feature, I haven't seen a similar UI concept for hosting / snapping.
For authentication and authorization there are various approaches - one nice solution is to use Apache zookeeper (a key/value store) as a basis for a simple user management component that can be available to all your services.
