Linux-Stammtisch Munich

For all Ceph interested people in Germany, especially Bavaria: There will be a Linux-Stammtisch next week on 24.11.2015 in Munich. I will present about "Ceph - Overview, Experiences and Outlook". If you are interested, the meeting starts at 19:00 (CET) at the Paulaner Bräuhaus. You find more information and can register here.

There will be also a talk held by Andreas Pöschl from BMW. The topic is: "Erfahrungen bei der Integration von Open Stack in eine Enterprise-Umgebung". And for sure there will be time for networking and beer after the talks and discussion.

SUSECon 2015

Back from OpenStack Summit in Tokyo. It was really a interesting conference with many interesting meetings, a lot interesting talks and also events. 

Yesterday I travelled to Amsterdam to attend the SUSECon '15. It's not the same kind of conference like the OpenStack Summit, but it will be interesting to attend. Many - also Ceph and OpenStack related - talks, hands-on, technical tutorials and workshops. And it's a place to meet other customers and discuss about their experiences with OpenStack, Ceph and SUSE.

OpenStack Summit Tokyo 2015

Yesterday I conducted my presentation about "99.999% available OpenStack Cloud - A builder's guide". The room was full. If you could not join, you can find the slide deck on slideshare and the video is also already available online.

If you have been in Tokyo and seen my talk I would really appreciate if you fill out the official feedback form. Feel also free to send me also direct feedback if you like.

The main conference ended also yesterday. Today is the last day of the Mitaka Design Summit with interesting meetings and your chance to participate into the planning for the next OpenStack release.

OpenStack Summit Tokyo 2015: Vote for Presentations

As mentioned before: then next OpenStack Summit will take place in Tokyo, Japan from 27-30 October 2015. The "Call for Speakers" ended some days ago and now the vote for presentation period started and will end 30. July, 11:59 PDT (31. July  6:59 UTC / 08:59 CEST). 

I've submitted for Toky two talks:

• "99.999% available OpenStack Cloud - A builder’s guide" - This talk will provide insight in how to build a highly available OpenStack cloud together with Ceph in a classical highly available data centers with e.g. two fire compartments and redundant infrastructure. The focus will be on failure scenarios and their impact on OpenStack and Ceph components, quorum devices you have to consider, strategies on how to ensure quorums and keep the cloud running, pitfalls and solutions.
• "NFV orchestration powered by OpenStack" - This talk would be about existing OpenStack orchestration projects and how they can be used to manage a NFV Cloud, how they integrate, what is missing, and how to map these projects on the ETSI-NFV model.

You can vote, if you are interested to see my talks [1][2] at the summit, every vote is highly welcome. You can find a full abstract at the voting page.

My colleague Ralf Trezeciak submitted also a NFV related talk. He will appreciate your votes for sure, if you are interested in the presentation.

There is a long list of interesting Ceph related talks, simply use the search field on the voting page. I may provide a list in an additional post later.

The talk will provide insight into requirements for a secure setup and potential issues, pitfalls, and attack vectors against storage technologies used with an enterprise OpenStack cloud. We will present what Deutsche Telekom and Red Hat/Inktank, together with the community, are working on to build a security critical cloud with OpenStack and Ceph.

You can vote, if you are interested to see our talk at the summit, every vote is highly welcome. You can find a full abstract at the voting page.

My colleague Marc Koderer submitted this year two talks [1][2]. These are unrelated to Ceph, but he will appreciate your votes for sure, if you are interested in them.
