[Cephalocon-seoul-2020] Keynote

Hi Myoungwon, John, Jaesuk, Jugwan, everyone, We have an open keynote slot to fill for the second day of the conference. Last year in Barcelona we invited SWITCH to present about their use of Ceph to support Swiss academia and science. This year we'd love to have someone for Seoul that is local to South Korea. There were a few talks that we accepted that caught our eye: - "Journey for Provisioning 20k Over Rbd Volumes to Kubernetes With Openstack" by Junyoung, Sung at NAVER. - "Experiences of running RadosGW with billions of objects" by Ilsoo Byun at LINE None of us on the program committee know them or have seen them speak so we don't really have any sense of whether they would be prepared to do a keynote or not. Can you think of other large South Korean users that might make for a good keynote? Myoungwon, would something from SK Telecom make sense? Or does anyone know of other large users we could invite that would be comfortable presenting in English? We could also ask someone from China (e.g., maybe Xie Xingguo from ZTE or Haomai Wang from XSKY) if we can't find a good Korean candidate. If we can't find a local user, our fallback is probably to ask Tom Byrne of STFC (UK) to do his talk as a keynote. He runs one of the larger clusters around and his talks have historically been quite good. Thanks! sage
