DevOps is a methodology that integrates software development (Dev) and IT operations (Ops) to streamline the software development lifecycle (SDLC). It focuses on improving collaboration, automating workflows, and ensuring faster, high-quality software delivery. By adopting Agile, Scrum, and Kanban methodologies, DevOps enhances efficiency and reduces deployment cycles.
Who Is a DevOps Engineer?
A DevOps Engineer is a professional who blends software development and IT operations expertise to automate, manage, and optimize the software delivery process. Their responsibilities span coding, infrastructure management, testing, deployment, and system monitoring. Depending on their specialization, they may focus on automation, cloud infrastructure, security, or system architecture.
