Hello, If your setup has a single user database, so all users are under the same administrative domain, what you describe is like having different Openstack Regions, or different Nova Cells. I would suggest to look into Multi Region that is the easier to implement. http://docs.openstack.org/arch-design/multi-site-architecture.html
If your setup has users in the two clouds that are managed under two different administrative domains, then what you are talking about is Cloud Federation. We had a discussion about it in Machester: https://etherpad.openstack.org/p/MAN-ops-Keystone-and-Federation If your university is interested in Federation you should be aware of this workshop: https://eventr.geant.org/events/2527 Cheers, Saverio 2016-09-30 8:06 GMT+02:00 Michael Stang <michael.st...@dhbw-mannheim.de>: > Hello all, > > I have a question if it is possible to connect 2 Openstack clouds to use the > ressources together? > > We have a Mitaka installation at our site and we have colleagues who also > have a mitaka installaton at their site which are both independent at the > moment.
