OpenNebula is a great cloud orchestration and management tool, characterised by its flexibility, durability and focused feature matrix. A feature matrix that is driven largely by real world problem scenarios and real world feedback : something that has been the focus of CentOS project as well. From large scale deployment automation to patch management and state control, the CentOS Project aims to solve real world problems faced by the people who run infrastructure : The Sysadmins administrators and operations teams. During this talk, I will share why OpenNebula and CentOS Linux are a perfect match and go into some user stories that demonstrate this relationships success in real world scenarios. Bio: Karanbir Singh is a London based sysadmin working in the web operations and large scale linux systems architecture domains, and since 2009 has been the Project Leader for The CentOS Project. An old hat Devops proponent, he’s a bit believer in high precision monitoring, aggressive automation and business centric operations.
