Ultimately, DevOps is an approach to Agile development. It focuses on every member in the software development life cycle collaborating to ensure software is released quickly without impacting quality.
This include development and operations, of course, as well as quality assurance, testers, business owners, clients, and project managers.
A Little More About Agile
With Agile, teams are getting software ready for release through development and always keep it completely functional so it can be delivered at any time.
Additionally, Agile specifically emphasizes a more collaborative relationship between departments so that teams could respond effectively to feedback and change, while releasing new features, functionalities, and improvements regularly.
Like we mentioned, the creation of the term DevOps is a reaction to the shift to Agile development. Because of the disconnect and isolation of teams prior to the DevOps movement, these goals were much harder to accomplish.
“Since the Agile methodology was only implemented during the development phase, the operations departments was left behind, leading to deployments piling up faster than it was possible to release them.”
As organizations adopted Agile mentality, conjoining teams under DevOps was common sense to improve cross-departmental.
