6 www.rackspace.com Why Ansible with OpenStack? •  Only SSH and Python required on the target device, no clients/agents; can manage an environment of any size or type! •  Existing Ansible modules for overall Linux management and OpenStack; working with OpenStack is like working with a complicated Linux kernel! •  Playbooks can be written against API’s or Python CLI’s! •  Designing roles with unique variable values is as easy as writing a email"
