DevOps is a set of practices that combines software development (Dev) and IT operations (Ops) to shorten the systems development life cycle and deliver high-quality software continuously. By fostering a culture of collaboration and shared responsibility, DevOps aims to improve deployment frequency, achieve faster time to market, and maintain system stability and reliability. Key practices include continuous integration and continuous delivery (CI/CD), infrastructure as code (IaC), and monitoring and logging. Implementing DevOps enables organizations to respond more effectively to customer needs and market changes, enhancing overall business agility.
