![]() In 2016, the DORA metrics for throughput (deployment frequency, lead time for changes), and stability (mean time to recover, change failure rate) were published in the State of DevOps report. Also in 2014, Lisa Crispin and Janet Gregory wrote the book More Agile Testing, containing a chapter on testing and DevOps. They stated that the adoption of DevOps was accelerating. Īs of 2014, the annual State of DevOps report was published by Nicole Forsgren, Gene Kim, Jez Humble and others. In 2012, a report called “State of DevOps” was first published by Alanna Brown at Puppet Labs. The conference has now spread to other countries. The conference was founded by Belgian consultant, project manager and agile practitioner Patrick Debois. In 2009, the first conference named DevOps Days was held in Ghent, Belgium. ![]() Īround 20, concerns were raised by those within the software development and IT communities that the separation between the two industries, where one wrote and created software entirely separate from those that deploy and support the software was creating a fatal level of dysfunction within the industry. Proposals to combine software development methodologies with deployment and operations concepts began to appear in the late 80s and early 90s. At its most successful, DevOps is a combination of specific practices, culture change, and tools. However, the term is used in multiple contexts. Most often, DevOps is characterized by key principles: shared ownership, workflow automation, and rapid feedback.įrom 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". Other than it being a cross-functional combination (and a portmanteau) of the terms and concepts for "development" and "operations", academics and practitioners have not developed a universal definition for the term "DevOps". DevOps is complementary to agile software development several DevOps aspects came from the agile way of working. ![]() Used as a set of practices and tools, DevOps integrates and automates the work of software development ( Dev) and IT operations ( Ops) as a means for improving and shortening the systems development life cycle. DevOps is a methodology in the software development and IT industry. ![]()
