What is the main focus of the DevOps methodology?

The DevOps methodology primarily emphasizes collaboration between development and operations teams to facilitate the continuous delivery of software. This approach seeks to improve the speed and quality of software development by fostering an environment of shared responsibilities and improved communication.

By integrating development and operational tasks, teams can automate processes, streamline workflows, and ensure that software can be deployed quickly and reliably. The focus on continuous delivery means that updates and changes can be implemented frequently, making it easier to adapt to user feedback and evolving business needs, thus enhancing overall responsiveness in software development.

In contrast, securing applications post-development, managing traditional databases, and enforcing data structure security do not encapsulate the core principles of DevOps, which center around collaboration, automation, and iterative improvement in the software lifecycle.
