Different People understand DevOps differently. In majority of cases people focus only on Tools and believe DevOps is all about tools. Few people start with processes related to software engineering or technical excellence and try to over-engineer them. Very few people holistically understand what DevOps means and how DevOps can help business value delivery. Don’t get me wrong here – It’s okay to start with tools or process focus, however that’s not what DevOps is all about.
