DevOps is a term used to refer to a set of practices that emphasize the collaboration and communication of both software developers and information technology (IT) professionals while automating the process of software delivery and infrastructure changes. It aims at establishing a culture and environment, where building, testing, and releasing software can happen rapidly, frequently, and more reliably. Wikipedia (2017)
DevOps is a culture, movement or practice
DevOps is a term used to refer to a set of practices that
emphasizes the collaboration and communication of
both software developers and other information-
technology (IT) professionals while automating the
process of software delivery and infrastructure changes.
DevOps represents a change in IT culture, focusing on rapid IT service delivery through the
adoption of agile, lean practices in the context of a system-oriented approach. DevOps
emphasizes people (and culture), and seeks to improve collaboration between operations and
development teams. DevOps implementations utilize technology — especially automation tools
that can leverage an increasingly programmable and dynamic infrastructure from a life cycle
DevOps is the union of people, process, and products to
enable continuous delivery of value to our end users.
