Why devops is required?
Before 2000 software engineers use waterfall methodology to update the software they have made and because of large scale devlopment projects, teams take months to update and devlop that.
Next, they give to qa's to check the quality and code of the software and they take time near around months and the whole process of releasing one software took months and years .
To improve speed and devlopment quality now software engineers use agile methodologies, which are iterative rather than linear focused. Chief among these methodologies are continuous integration and continuous delivery or ci/cd.
