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.
