You will explore why Linux is the backbone of modern DevOps, dominating cloud images and providing native support for container ecosystems like Docker and Kubernetes. The overview also covers popular distributions—such as Ubuntu, Fedora, and RHEL—and explains the kernel's role in managing system hardware, memory, and processes.
