Tomorrow the German OpenStack Days 2016 (Deutsche OpenStack Tage) will start in Cologne. I will give a talk on Ceph and OpenStack about "OpenStack at 99,999% availability with Ceph".
It seems the event is already sold out completely, but as far as I know the presentations (mostly conducted in German) will be recorded and available after the conference. If you have already a ticket, have a interesting OpenStack conference in Cologne!
