DevOps is a methodology evolved from existing software development methodologies over the years to meet customer requirements more efficiently. In a traditional waterfall model, the requirements are completely fixed and signed off before the next phase of design is initiated and so on for each phase. In the agile development methodology, the requirements change frequently and projects were executed with short release cycles. Every release incorporated customer feedback and bug fixes. However, the agile methodology lacked a collaboration between development and operations teams which slowed down the release process. DevOps methodology adds flexibility to agile development methodology. It was created to seamlessly integrate the development and operations, the process enabled continuous project delivery.
