11. Design Summit Sessions - Glance (Icehouse) 1. Image status consistency with Nova 2. Properties/Status per location 3. Deprecate API v1 in J* 11

12. OpenStack Design Summit – The day after Icehouse Etherpads https://wiki.openstack.org/wiki/Summit/Icehouse/Etherpads Session Videos http://www.openstack.org/summit/openstack-summit-hong-kong- 2013/session-videos Photos http://www.flickr.com/photos/108527511@N02/with/10830960026 12

13. OpenStack Design Summit – The day after Infrastructure "refresh" when moving into OpenStack We are finding the same "problems" at scale Hybrid and Federated clouds interest growing Lots of projects/ideas around but focus in "stability" in core components 13
