Quick introduction

11 April 2023

DevOps is an alternative model for the creation of business value from the software development life-cycle that encompasses a

product-centric view across the entire product life-cycle (from inception to retirement) and recognises the value in close collaboration,

experimentation and rapid feedback.”- http://blog.devopsguys.com/2014/04/16/devops-organic-versus-transformational-devops/
