Agile Mëtteg 15 December 2011 Developers vs. Operations This is what we are (sadly) used to. Devops is a set of practices, principles, and methods allowing for a better collaboration and a deeper understanding between these two worlds (and further on, between these domains and the users/stakeholders). It is addressing the part of Agility that's not fully adressed usually in Agile approaches. This free Agile Mëtteg session will present you with the principles behind Devops, and also detail some of the practices. Hopefully you'll have all the necessary keys to unlock the doors between development teams and operations teams.
