It stores data in various backends. The default is SQL, and many use LDAP to link with existing ID stores. It runs as a REST API in front of those data backends, and scales out quite nicely like any other web application. > b.

Does Rackspace today do it or any other public cloud? > Yes it is expected to be exposed. Users authenticate to keystone and are given a token which can be used to grant access to the other OpenStack services. > Some horizon questions also > > a.

Go wild. ;) I believe there are hooks for skins/themes, and one can add plugins for other functionality. > b. It seems like Horizon is basic right now, do vendors provide their > own GUI for customers? > See horizon.hpcloud.net for a public cloud provider (disclosure: my employer) using Horizon. > c.

Is there a standardized agent or > something that runs on hardware? > Horizon isn't really about "servers" and "arrays". It is meant as the interface for the users of the cloud, not the operators. _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : [email protected] Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
