Linux
From ProWiki - Demo and Test Wiki
Linux is a family of open-source, Unix-like operating systems based on the Linux kernel, first released by Linus Torvalds in 1991. It is the dominant operating system for servers, cloud infrastructure, and containerized workloads.
Key Characteristics
- Open-source kernel licensed under GPL 2.0
- Available in many distributions (Ubuntu, Red Hat, Debian, SUSE, etc.)
- Multi-user, multi-tasking with strong security model
- Package management systems (apt, yum, dnf, pacman)
- Dominant platform for web servers, databases, and cloud workloads
- Foundation for Android and container runtimes (Docker, Kubernetes)
Enterprise Use
Linux powers the majority of enterprise server infrastructure, cloud platforms (Microsoft Azure, AWS, Google Cloud), and containerized microservices. Red Hat Enterprise Linux (RHEL) and Ubuntu LTS are the most commonly used enterprise distributions. Many open-source enterprise tools including Git, GitLab, Mattermost, OpenVPN, and DokuWiki are developed and deployed primarily on Linux. Developer workstations running Linux are common in engineering teams.
