DevOps & Agile Software Development

With these requirements, software developers leave the traditional, linear waterfall approach behind them and instead choose an iterative methodology. Customers and project supervisors are networked together and give each other regular feedback on the project status at short intervals. New code is tested immediately, so there are results available on a weekly or even daily basis, and new or modified customer requirements can be integrated into the workflow without delay. The Scrum and Kanban procedural models are a key component in iterative and incremental software development.

One could say that DevOps perfects the concept of agile software development, or at least that it takes it a step further. The teams work closely together and discuss from the beginning what Dev can do for Ops and what Ops needs from Dev in order to subsequently transition with the software product into stable productive operation. The automating of processes during application development is another feature of DevOps. Using CI/CD pipelines, development cycles are largely automated in order to accelerate product delivery. Ideally there is a mixed Development/Operations team to ensure interdisciplinary workflows. At the same time, DevOps aims to integrate all stakeholders into a project from the word go: alongside Dev and Ops, this also includes Testing, Quality Assurance, Security of course the customer itself.
