Re: [openstack-dev] Replication multi cloud
Hi Chmouel, using this approach should I need to have the same users in both keystone? Is there any way to map user A from cloud X to user B in cloud Y? Our clouds have different users and replicates the keystone could have some problems, not only technical.

Re: [openstack-dev] Replication multi cloud
You may be interested by this project as well : https://github.com/stackforge/swiftsync you would need to replicate your keystone in both way via mysql replication or something like this (and have endpoint url changed as well obviously there).

Re: [openstack-dev] Replication multi cloud
Thanks Donagh, I will take a look to the ontainer-to-container synchronization to understand if it fits with my scenario.

Re: [openstack-dev] Replication multi cloud
Marco, The replication *inside* Swift is not intended to move data between two different Swift instances -- it's an internal data repair and rebalance mechanism. However, there is a different mechanism, called container-to-container synchronization that might be what you are looking for. It will sync two containers in different swift instances. The swift instances may be in different Keystone administrative domains -- the authentication is not based on Keystone. It does require that each swift instance be configured to "recognise" each other. However, this is only usable for low update rates. Regards, Donagh -Original Message- From: Fargetta Marco [mailto:marco.farge...@ct.infn.it] Sent: 13 March 2014 11:24 To: OpenStack Development Mailing List Subject: [openstack-dev] [swift] Replication multi cloud Hi all, we would use the replication mechanism in swift to replicate the data in two swift instances deployed in different clouds with different keystones and administrative domains. Is this possible with the current replication facilities or they should stay in the same cloud sharing the keystone? Cheers, Marco -- Eng.
