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.
