Instead of picking technologies first and adapting processes and people to it a real DevOps process begins from the change in organisation culture.
Based on principles of Lean Manufacturing and automate everything, DevOps combines software development and system operation capabilities into a single team. This team will be capable of taking care of their solution throughout its life cycle. Although rooted in high-tech, DevOps thrives in a human centric and innovation driven culture that focuses on customer value.
