Why Devops is necessary ?

What is Devops ?

• DevOps typically refers to the emerging professional movement that advocates a collaborative working relationship between Development and IT Operations, resulting in the fast flow of planned work (i.e., high deploy rates), while simultaneously increasing the reliability, stability, resilience of the production environment.
• DevOps means that you see the end to end delivery system from concept to production, your DevOps scope is any group that are involved in that workflow. So if you're willing to make a cultural investment in changing how you work, then you can start to implement some of the working practices that DevOps recommends.
• In IT, DevOps is recognized as a cultural approach. From job of point of view, it is a job description for a candidate who has the talent-skill to work as a Systems Operations engineer as well as a developer.
