Linux

Linux

Linux is the most widely used operating system kernel worldwide and forms the technical basis for a multitude of operating systems – so-called Linux distributions. It was developed in 1991 by Linus Torvalds; today, the kernel is collaboratively developed by thousands of developers from all over the world and is licensed under the GNU General Public License (GPL).

The Foundation of the Internet and Modern Infrastructure

Linux has established itself as the dominant operating system in data centers, on servers, and on the internet. The vast majority of all web servers, cloud platforms, and supercomputers worldwide run on Linux. Whether public cloud infrastructures like AWS, Google Cloud, or Azure, highly available database clusters, or container platforms – Linux is the foundation upon which modern IT infrastructure is built.

The internet itself would be almost inconceivable without Linux: routers, firewalls, DNS servers, mail servers, and almost all central network services are based on Linux. The combination of stability, security, scalability, and open standards makes Linux the preferred platform for mission-critical systems.

Diversity through Distributions

Linux itself is just the kernel. A Linux distribution combines the kernel with a package management system, system libraries, administration tools, and other software to create a complete, ready-to-use operating system. Depending on the application, support model, and community philosophy, there is a multitude of distributions – each with its own strengths:

• Debian – known for its stability and its complete focus on Free Software
• Ubuntu – widely used in enterprise and cloud environments, based on Debian
• Red Hat Enterprise Linux (RHEL) – frequently used in regulated enterprise environments
• AlmaLinux / Rocky Linux – community-maintained RHEL alternatives
• SUSE Linux Enterprise / openSUSE – strongly represented in the European enterprise segment

Overview of Linux Strengths

• Stability and Reliability – Linux systems often run for years without a reboot
• Security – transparent source code, fast security updates, granular rights management
• Scalability – from embedded systems to clusters with thousands of nodes
• Flexibility – adaptable for almost any purpose
• No License Costs – open-source licensing reduces total cost of ownership
• Large Community and Ecosystem – extensive documentation, active developer community, and a wide range of compatible open-source solutions

Professional Support for Linux

The use of Linux in productive environments requires expertise – in selecting the right distribution, in system hardening, in patch management, and in integration into existing infrastructures. credativ® supports you with comprehensive support for Linux-based systems: from consulting and planning to implementation and ongoing operation.
