DevOps is a collaborative approach that combines development (Dev) and operations (Ops) teams to streamline the software development lifecycle. By emphasizing automation, integration, and communication, DevOps accelerates the delivery of high-quality software while maintaining system stability and reliability. Key practices include continuous integration/continuous deployment (CI/CD), infrastructure as code (IaC), and monitoring. DevOps fosters a culture of shared responsibility, enabling teams to adapt quickly to changing requirements, reduce downtime, and enhance customer satisfaction in a fast-paced, agile environment.
