[occi-wg] Status of OCCI and OpenNebula

[Feldhaus, Florian]

Dear Gregor,

just one more thing. We are currently participating at the Cloud Plugfest and test all available OCCI implementations, improve them and discuss the interpretation of the specification. As we are especially focusing on testing OCCI for the EGI FedCloud you may want to join our discussions remotely. If you intend to do so, please register as a remote participant here http://www.cloudplugfest.org/next-event/registration and we can send you all information regarding chat room, test tools and test results.

I also missed to note the repositories for the rOCCI code. We split the code in a server part and a OCCI Core + Client part. The server part can be found here:
https://github.com/gwdg/rOCCI-server

The OCCI Core and Client can be found here:
https://github.com/gwdg/rOCCI

Cheers,
Florian

This framework is successfully used within the EGI Federated Cloud Task Force to manage the OpenNebula sites through OCCI. The rOCCI client has been tested against the rOCCI server and the OpenStack OCCI implementation and works with both.

We in FG are interested in finding more out about it (does it work for the newest version of OpenNebula, and so forth). Furthermore, we would appreciate any help from the community to discuss a community managed OpenNebula distribution on FG that supports OCCI.

The main reason it is private is manpower. Thus we thought we could use OpenNebula to identify if it is possible to identify if users can set up their on managed clouds.
>> The idea came based on an experiment that we ran on Openstack Essex, where we for example developed a one line command so that a novice user could set up an entire virtual cluster with a couple of options such as a label and the number of worker nodes. This did set up one or more slurm clusters each with its own virtual worker nodes. Now we started thinking further.

>> 
>> 	Recently we developed a new tool that allows us more easily to "redistribute" resources to different clouds and it may be the right time to look into how to best set up a "public" OpenNebula cloud with what I term cloud-shifting e.g. resources can be moved on demand into a particular cloud IaaS framework. This allows us for example to move resources from a batch queuing system to Eucalyptus, to OpenStack, naturally we are interested to do the same with OpenNebula as this seems to be a IaaS framework the OCCI community is often referring to. Any thoughts?
