SUSECon '13 - third day

Thursday morning started for me with a presentation titled "Intel and OpenStack: Contributions and challenges". Krish Raghuram explained not only how Intel helps OpenStack to work great on Intel hardware but also how Intel uses OpenStack internally. For example, they have their own OpenStack private cloud where they run 1,500,000 (hope I got all the zeros right;-) VMs across data centers. Interesting was the concept of geolocation in the cloud: With trusted computing, an image can be encrypted and then will only run in certain geos, e.g. countries. If only the diagram wouldn't look that complex...

The next presentation I attended was by Udo Seidel about "Petabyte scale out Rocks - Ceph as Replacement for Openstack's Swift and Co". He first introduced ceph and explained how it's scalable, has a flexible configuration and not a single point of failure. Ceph can also be used in OpenStack as an alternative to OpenStack Object Storage (Swift), as backend for OpenStack Block Storage (cinder) and
also as storage for OpenStack Image Service (glance).  A single backend for these kinds of storage is a quite clever idea.

I listened again into our SLE 12 systems management outlook session and was happy that I had the evening off - and concluded the evening with a good time at the pool looking at the moon, swimming, sliding and talking.

Photos from the day have been added again to my gallery.
