Linux for Business Networks: The Current State

Key points:

  • Enterprise Linux distributions, such as Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES), are the foundation of modern networking setups, providing reliable and secure platforms for data centers, cloud systems, and edge devices.
  • Networking capabilities are a key differentiator among Linux distributions, with features like encrypted DNS, Network Function Virtualization (NFV), and Software-Defined Networking (SDN) support.
  • Purpose-built Linux-based networking operating systems, such as SONiC and Nvidia Cumulus Linux, offer hardware-agnostic and modular solutions for switches and other networking devices.

As a reporter, I have been investigating the latest developments in the world of Linux operating systems and their role in shaping the modern networking landscape. According to sources, Enterprise Linux distributions have become the backbone of modern networking setups, providing a reliable and secure platform for data centers, cloud systems, edge devices, and telecom networks. These distributions, such as Red Hat Enterprise Linux (RHEL) and SUSE Linux Enterprise Server (SLES), offer long-term support, compatibility, and specialized features for telecommunications and general networking.

RHEL, in particular, has been a pioneer in the enterprise Linux market, with its latest release, RHEL 10, offering post-quantum cryptography (PQC) support, optimized cloud integration, and improved SELinux for security. RHEL also integrates the Podman container platform, which is a competitive offering to Docker containers used by other vendors. Additionally, RHEL’s OpenShift is a leading Kubernetes cloud-native distribution, providing optimizations and easier integration.

Other Linux distributions, such as Ubuntu, have also made significant strides in the networking space, with features like Netplan, a YAML markup-based declarative configuration tool, and Open vSwitch, which supports IPv4/IPv6, DHCP, and SDN deployments. SLES, on the other hand, has standardized on NetworkManager and offers features like NFTables firewall framework and KEA DHCP server.

However, it’s not just general-purpose Linux distributions that are making waves in the networking space. Purpose-built Linux-based networking operating systems, such as SONiC and Nvidia Cumulus Linux, are also gaining traction. SONiC, which was launched by Microsoft in 2016 and became a Linux Foundation project in 2022, is a Debian Linux-based open network operating system for switches that is largely hardware-agnostic and modular. Nvidia Cumulus Linux, which was acquired by Nvidia in 2020, offers features like Unnumbered Interfaces and Prescriptive Topology Manager (PTM).

As the networking landscape continues to evolve, it’s clear that Linux distributions will play a critical role in shaping the future of cloud and networking. With their focus on long-term support, compatibility, and specialized features, Enterprise Linux distributions and purpose-built Linux-based networking operating systems are well-positioned to meet the demands of modern networking setups. As a reporter, I will continue to monitor these developments and provide updates on the latest trends and innovations in the world of Linux and networking.
