Following the success of the same event at the Tokyo and Austin summits, all this is is a place and ops will gather here. Apparently good things will happen, but it's completely unstructured and informal, so who knows what will occur!
The Ops Meetup, organized by the User Committee, is a track comprised of collaborative, working sessions for people who are operating OpenStack clouds (and contributors who want to hear from them). The purpose is to share knowledge and best practices among cloud operators, as well as provide feedback based on experience running OpenStack. There will be no formal presentations, and a moderate level of knowledge around running OpenStack is assumed. If you're just starting out, the Operations Track of the conference will be much more friendly!
