Open Stack

At CERN, we're running cells for scalability. When you go over 1000 hypervisors or so, the general recommendation is to be in a cells configuration.

Cells are quite complex and the full functionality is not there yet so some parts will need to wait for Havana.

Subject: [Openstack] Cells use cases

Hello all,
I've really interested in  cells but unfortunately i can't find any useful use cases of them.
For instance I have 4 DCs and I need single entry point for them. In this case cells are  a bit complicated  solution. It's better to use multiple regions in keystone instead

The only one good reason for cells, which I've found, is to organize so-called failure domains, i.e. scheduling on another DCs in case of failures.

Does anyone have different use cases or vision on cells usage?
Thanks in advance.
