DevOps
DevOps is the integration and automation of the software development and information technology operations. DevOps encompasses necessary tasks of software development and can lead to shortening development time and improving the development life cycle. According to Neal Ford, DevOps, particularly through continuous delivery, employs the "Bring the pain forward" principle, tackling tough tasks early, fostering automation and swift issue detection. Software programmers and architects should use fitness functions to keep their software in check.
Although debated, DevOps is characterized by key principles: shared ownership, workflow automation, and rapid feedback. 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". However, the term is used in multiple contexts. At its most successful, DevOps is a combination of specific practices, culture change, and tools.
Proposals to combine software development methodologies with deployment and operations concepts began to appear in the late 80s and early 90s.
In 2009, the first conference named DevOps Days 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, a report called "State of DevOps" was first published by Alanna Brown at Puppet Labs.
As of 2014, the annual State of DevOps report was published by Nicole Forsgren, Gene Kim, Jez Humble and others. They stated that the adoption of DevOps was accelerating. Also in 2014, Lisa Crispin and Janet Gregory wrote the book More Agile Testing, containing a chapter on testing and DevOps.
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. However, the research methodology and metrics were criticized by experts. In response to these criticisms, the 2023 State of DevOps report published changes that updated the stability metric "mean time to recover" to "failed deployment recovery time" acknowledging the confusion the former metric has caused.
DevOps Research and Assessment (DORA) has developed a series of metrics which are intended to measure software development efficiency and reliability. These metrics include:
