Zones is going through some radical changes currently. Specifically, we're planning to use direct Rabbit-to-Rabbit communication between trusted Zones to avoid the complication of changes to OS API, Keystone and novaclient. To the user deploying Nova not much will change, there may be a new

Sandy, I am excited to hear about the work that is going on around communication between trusted zones and look forward to seeing what you have created. In general, the scalability of Nova is an area where I think we need to put additional emphasis. Rackspace has done a lot of work on zones,

This is getting really interesting !! I really hope to see the new Zones code merged into Essex, since we are really planning a production implementation on Essex, as soon as it is marked as a release ( nova, keystone, glance swift, wich also we got it working on a big lab environment with

The approach here looks solid, but I'm not sure if it goes far enough. One issue that Keystone has to resolve eventually is how to authenticate request for tenant-specific file system users. Basically the core authentication system allows satellite authentication systems to authenticate users
