DevOps

DevOps is a set of software development practices that combine software development (Dev) and information-technology operations (Ops) to shorten the systems-development life cycle while delivering features, fixes, and updates frequently in close alignment with business objectives. Academics and practitioners have not developed a unique definition for the term 'DevOps.' From an academic perspective, Len Bass, Ingo Weber, and Liming Zhu — three computer science researchers from the CSIRO and the Software Engineering Institute — suggested defining DevOps as 'a set of practices intended to reduce the time between committing a change to a system and the change being placed into normal production, while ensuring high quality'. The term DevOps, however, has been used in multiple contexts. In 2009, the first conference named devopsdays was held in Ghent, Belgium. The conference was founded by Belgian consultant, project manager and agile practitioner Patrick Debois. The conference has now spread to other countries. In 2012, the State of DevOps report was conceived and launched by Alanna Brown at Puppet.As of 2014, the annual State of DevOps report is published by Nicole Forsgren, Gene Kim, Jez Humble and others.In 2014, they found that DevOps adoption was accelerating. Also in 2014, Lisa Crispin and Janet Gregory write the book More Agile Testing, containing a chapter on testing and DevOps. In 2015, Nicole Forsgren, Jez Humble and Gene Kim found DORA: DevOps Research and Assessment.
