I would like to understand the role of a DevOps Engineer in modern software development and IT operations. What are the key responsibilities they handle, such as managing CI/CD pipelines, automating infrastructure, monitoring systems, and improving collaboration between development and operations teams? Which tools—like Docker, Kubernetes, Jenkins, Git, Terraform, Ansible, and cloud platforms such as AWS, Azure, and Google Cloud—are most commonly used by DevOps Engineers in their daily work? Additionally, what skills—like scripting, automation, cloud management, and system monitoring—are essential for someone pursuing a career in DevOps, and how does this role help organizations deliver software faster, more reliably, and at scale?
