Hi, The OpenNebula team has contributed a Deltacloud driver to manage OpenNebula instances through the OCCI API [1], as Csom said. Also, apart from the group, OpenNebula can use Deltacloud to build Hybrid Clouds [2] Regards [1] http://blog.opennebula.org/?p=342 [2] http://blog.opennebula.org/?p=569 2010/6/30 Csom Gyula <csom@interface.hu>
It seems interesting to me (though I'm an outsider here:))...
* The deltacloud domain is not yet as rich as OCCI's. That is no management for storage, network, yet. Meanwhile it puts strong emphasis on virtual machine templates (or in deltacloud terms: 'hardware profiles') [1].
* Architecturally it follows a slightly different approach. Unlike OCCI which focuses on the communication layer, deltacloud seems to support a 2-layered approach and focuses on the API layer built on top of the communication layer [1,2]. Meanwhile it is not yet language- agnostic: currently it only supports Ruby [1]. The whole thing (the architectural concept) remembers me libvirt (another RedHat lib) [3].
* Since RedHat recently submitted the library to Apache it might gain popularity. [4]
* Another interesting thing is that OpenNebula's deltacloud driver is built on top of OCCI [5].

Just wondering if folks have been following Delta Cloud. I was introduced to it today and look at it briefly - looks interesting. http://deltacloud.org/ - Michael (R2AD)
