Devops is not a new tool/Technology in the market.
It is a new culture or process to develop,release and maintain software
products/projects/applications with high quality in very faster way.
We can achieve this in devops by using several automation tools.
For any software development,release and maintenance, there are two groups of
engineers will work in the company.
1) Development Group
2) Non-Development Group or Operations Group or Administrators Group.
Again this classification can be divided into small sets of groups.
