The role of a DevOps culture in software development is to promote collaboration and communication between software development and IT operations teams. This cultural shift aims to break down silos, enable faster delivery of software updates, and improve overall quality. By adopting DevOps practices, organizations can implement continuous integration and continuous delivery (CI/CD) pipelines, automate testing, and encourage a culture of shared responsibility. This ultimately leads to increased efficiency, faster response to market needs, and a more reliable software development process.
