What problems does he solve?

There are a variety of ways to execute software product development. If the application is a small scale application, let’s say a website or maybe just a mobile app, the development won’t be very tough to achieve.

But things do change when you have a big scale application to build. There will be multiple teams working together on a single product, discussing complex architectures; significantly, the DevOps concept will decrease the software failure probability.
