DevOps is a set of practices that emphasizes collaboration between development (Dev) and IT operations (Ops) to streamline software development and deployment processes. Cloud computing complements DevOps by providing scalable and flexible infrastructure resources on-demand, allowing organizations to quickly deploy and manage applications, improving agility and cost-efficiency. The combination of DevOps and the cloud enables faster development cycles, continuous integration and delivery, and enhanced scalability, making it a fundamental approach for modern software development and operations.
