[Openstack] Global deployment of Glance

2011-05-17 Thread Glen Campbell
If we are going to deploy Glance to support a global deployment of Nova, would it make sense to have replicas in different regions for better performance? Or, to put it another way, is there a recommended way to keep multiple Glance installations in sync? Users doing snapshots/backups, etc.,

Each zone should definitely have glance instances, IMO. At least two per zone for redundancy and networking reasons in large OpenStack installations. There's some work to do to support this, though. - Chris On May 17, 2011, at 8:59 AM, Glen Campbell wrote: If we are going to deploy Glance

Assuming you are using Swift for storage, the Swift ring configuration can specify zones and minimum number of replicas, which could handle all this logic and bit pushing for you. -Eric On Tue, May 17, 2011 at 06:36:38PM +, Glen Campbell wrote: That's probably the easiest to implement. This

[Openstack] testing and deploying swift?

2011-05-17 Thread Jon Slenk
hi, So what are people's processes for tracking Swift releases, on production systems? I'm guessing Rackspace is probably the most serious deployment to date. If anybody there could comment on what release of Swift is being run and how you expect to deploy newer versions, that would be fun and

[Openstack] Discussion of network service flows

2011-05-17 Thread Troy Toman
As was mentioned in the networks meeting this afternoon, we need to open up a discussion around flows between Nova, Melange(IPAM), Quantum and Donabe. As we are refactoring Nova for networking and designing IP and Network services in parallel, it will be important to reach some agreement as to
