- In order to solve these kinds of problems DevOps engineers and tools are required to overcome the situation and code will work in any environment. We need a DevOps engineer to achieve software development in less time with more productivity; releases can happen very frequently, work can be divided into small tasks and assign to proper teams, we can roll back to the previous versions easily and it will reduce the cost to the company.
