2 OpenStack Design Summit Summary Swiss and Rhone Alpes - OpenStack User Group Meeting 6 th December, CERN Belmiro

My Design Summit Goals Operations "best practices" Scalability and architecture design Nova design sessions "shake" and "challenge" my knowledge and preconceptions with all user stories, products, companies, discussions… 3

Deep Dive into the CERN Cloud Infrastructure 4

OpenStack at CERN +3 Children Cells – Geneva and Budapest Computer Centers HA+1 architecture Integrated with CERN accounts and network infrastructure Monitoring OpenStack components status Ceilometer Glance - Ceph backend Cinder - Ceph backend 5

OpenStack at CERN by Numbers Adding +100 compute nodes every week Today we have: ~ cores ~ 3500 VMs 8

Design Sessions 9

Design Summit Sessions - Nova (Icehouse) 1. Live Upgrades 2. Scheduler redesign 3. Nova API v3 4. Cells 10

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

OpenStack Design Summit – The day after Icehouse Etherpads Session Videos /session-videos Photos 12

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
