When the application doesn’t work, nobody wants to hear the phrase “the problem is on your side” from colleagues. As a result, users suffer and the client is unsatisfied – and they don’t care which part of the team is responsible for the breakdown. In the past, there was a barrier between developers and IT operators(admins). It sounds paradoxical, but they had different goals, although they work on the same product. The development goal is to implement business requirements as quickly as possible and add them to a working product. Admin is responsible for so that the product works stably – and all the changes put stability at risk. So, there is a conflict between them – DevOps has appeared to solve it. DevOps culture came just to bring development and IT operations together and unite them in common responsibility for the final product.
