Key aspects of DevOps in software development include collaboration, automation, and continuous integration and delivery (CI/CD). By breaking down silos between development and operations teams, DevOps fosters a culture of communication and shared responsibility, leading to improved deployment frequency and faster time-to-market for applications. Automation tools streamline processes such as testing and deployment, reducing manual workload and errors. CI/CD practices ensure that code changes are tested and deployed rapidly, enhancing software quality and enabling quick responses to user feedback.
