Recently, I presented at the international SPICON 2016 - theme of "Energizing Delivery in a Digital Paradigm". I spoke about how DevOps is quintessential for IOT solution development and the feedback was very encouraging from the audience. You can find my presentation here. I have been actively evangelizing devops as a philosophy in IOT solution development.
There is so much material on DevOps that I wouldn't want to add to it, however a slightly different take - DevOps definition is analogous to the blind men and elephant story that all of us have heard of. Enterprises who are thinking about DevOps as a magic wand to all their problems - let me implement Chef, Jenkins and Docker and voila all my problems are gone, must reconsider and reconsider really hard. You cannot be certified for DevOps, neither are there standards or checklists for implementing DevOps. I have also heard weird things such as DevOps is what Facebook, Google, Netflix does.
