An alternate approach is to tie data and potentially software to specific physical instances of a digital system. While such an approach would eliminate the ease with which we can share software and data, it could eliminate incidents where data is lost to attackers or where systems are attacked by malware.

DevOps is not a single system, rather it is a combination of many processes – testing, deployment, production, etc – thus, it’s better termed as a ‘distributed infrastructure’. Cloud-based solutions help to easily centralize all the distributed systems and processes and can be managed from the same place anywhere, anytime.

For example, for an internet shop, it may be a page with a product list, product details page, shopping cart, checkout, and so on. This saves clients traffic — sometimes traffic which the client is paying for. All of this means that it will be more costly because of the growing hardware requirement and a little bit faster.
