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.

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. -- Kind regards Dmitry Ukov IT Engineer Mirantis, Inc.
