DevOps plays a vital role in the software development lifecycle by promoting collaboration between development and operations teams. This cultural shift encourages continuous integration and continuous delivery (CI/CD), enabling faster and more reliable software releases. By automating processes and using version control, DevOps enhances efficiency, reduces errors, and improves overall product quality. Emphasizing real-time monitoring and user feedback, DevOps practices facilitate rapid iterations based on user needs. Ultimately, this approach drives innovation while maintaining a focus on operational stability and performance throughout the development lifecycle.
