DevOps is a cultural and technical approach that enhances the delivery of applications and services by integrating software development and IT operations, leading to faster product evolution. Originating in 2008 and gaining traction with the first DevOpsDays in 2009, it addresses the need for collaboration among various teams in software development. Training and certification programs, such as those offered by IIHT Vadapalani, aim to equip beginners with the necessary skills to succeed in a DevOps environment.
