I am doing some testing and will do some deployment on some remote hosts.

Remote hosts will use provider network only specific for each compute.

I was thinking, do I really need all the External, InternalAPI, Storage, StorageManagemnt, Tenant networks provided to all of the nodes? Maybe I could use a Provision network for all of that, and make swift/glance copy on all computes to provide local images.

I understand, if I do not have tenant network, all VM's in same project but in different sites, will not see each other, but it is ok at the moment. 

Thank you for your help
