We wrote before about the challenges a company will likely face when implementing devops. We provided a number of Devops good practices together with anti-pattern of how do and not to do things. We locked at the language people use when talking about Devops here and saw a practical example base on Rackspace Openstack to what challenges and problems the implementation can lead to here. Below is a nice video that help even better understand it. Happy devops watching ;).
Interesting slides from the movie
