Axiz advocates for SUSE Liberty Linux as an alternative solution ahead of CentOS 7 End-of-Life

     

2024 | New Press Release

Friday, 23 February 2024 – With the June 2024 end-of-life (EOL) date for CentOS Linux 7 approaching, businesses are faced with the urgent need to deploy a viable alternative to ensure sustainable business continuity..

While the tech community was taken aback by the unexpected discontinuation of CentOS Linux 7, SUSE had already laid the groundwork with the introduction of Liberty Linux some time ago. Now, as the EOL of CentOS 7 draws closer, Axiz is confident that Liberty Linux is a robust solution to seamlessly transitioning their operations without disruptions.

Liberty Linux, developed by SUSE, emerges as a reliable solution to address the void left by CentOS. Liberty Linux positions itself as a formidable player alongside alternatives such as Rocky Linux.

Built on SUSE’s Open Build Service tool using binary packages from Official Red Hat RPMs (SRPMs), Liberty Linux ensures compatibility while offering a distinctive approach. The kernel, based on the SUSE Linux Enterprise Server (SLES) kernel, is configured to maintain compatibility with RHEL/CentOS, providing a unique blend of stability and innovation.

Designed for mixed environments, Liberty Linux promises compatibility not only with SUSE Linux Enterprise Linux but also with openSUSE. It introduces features like SUSE Manager for streamlined management and task automation, making it an ideal choice for organisations seeking high availability, stability, and security.

“We understand the challenges organisations face with the impending changes in the Linux landscape. SUSE Liberty Linux is a viable solution that provides a seamless alternative to navigate these changes without disruptions,” said Terence Barter, Managing Executive at Axiz.

Liberty Linux offers 24/7/365 support through various channels, ensuring organisations receive timely updates, optimisation, and robustness. The operating system caters to environments requiring high availability, making it one of the standout alternatives in the current scenario.

From CentOS to openSUSE Leap: How to Feel at Home

July 8, 2023 | By: Juan Herrera Utande

Introduction

Welcome back to our blog series, where we delve into the world of openSUSE Leap and its appeal to CentOS users.

If you’re a sysadmin looking for a flexible and familiar Linux distribution, openSUSE Leap has got you covered. With a focus on inclusivity, openSUSE Leap incorporates tools and ideas from the SUSE community and beyond, enhancing flexibility and freedom of choice. This makes it a versatile platform that feels right at home for CentOS users.

In this blog post, we’ll explore how openSUSE Leap bundles a wealth of tools and technologies that align with CentOS, making your transition seamless and hassle-free. From installation to configuration and day-to-day operations, you’ll find familiar tools and concepts, resulting in a reduced learning curve and an effortless experience.

Familiar tools and frameworks in openSUSE Leap for CentOS users

Examples of core system components
available in both distros
Local filesystems ext4, XFS ext4, XFS, btrfs
Filesystem snapshots LVM+snapper LVM+snapper, btrfs+snapper
Package manager rpm, yum, dnf rpm, yum, dnf, zypper
Network devices configuration NetworkManager NetworkManager, Wicked
Security modules SELinux SELinux, AppArmor
Hardening framework openSCAP openSCAP
Firewall Firewalld Firewalld, SuSEFirewall2
System logging systemd-journald systemd-journald, syslog
System automation Ansible, Puppet Ansible, Salt, Terraform
High availability stack Pacemaker Pacemaker

Imagine you have to manage an openSUSE server that utilizes:

  • Ext4 file system with LVM volumes

  • SELinux binaries and libraries (with sample security policies available here)

  • firewalld for network security

  • Package management with yum or dnf

  • Network configuration through NetworkManager

  • Automated configurations with Ansible playbooks

Wouldn’t you feel right at home? The learning curve would be minimal.

For instance, in an openSUSE server, you can use yum/dnf or our very own zypper to manage repositories and install packages:

Easy, isn’t it?

And we’re only scratching the surface of system configuration. You can expect all the well-known Linux tooling to be available, just like in many other Linux distributions.

When it comes to package availability, openSUSE offers a vast library of packages through the Open Build Service (OBS), making it one of the biggest package repositories in the ecosystem. Moreover, both distributions support the use of Flatpak, a sandboxing technology that provides a safer way of delivering key software, immune to minor differences that may exist between distributions, such as package names, versions, or application and library paths.

Security and hardening

In today’s landscape, securing and hardening the entire OS is a formidable challenge for admins. Having access to security-certified software and widely adopted hardening frameworks and profiles is crucial, whether you use them as-is or as a starting point for your tailored approach.

While we’ll explore certification differences in a future blog, let’s focus on the hardening strategy.

Both openSUSE Leap and CentOS offer SCAP (Security Content Automation Protocol) with the openSCAP toolset. You’ll find it readily available and regularly updated. What’s more, openSUSE bundles both its own OVAL profiles and the ones from CentOS.

Both distributions also include the SCAP Workbench tooling, allowing you to customize and create hardening profiles. Additionally, industry-adopted hardening frameworks like CIS (Center for Internet Security) publish benchmarks that can be applied to openSUSE Leap using the SLES (SUSE Linux Enterprise Server) benchmarks. While there aren’t specific CIS benchmarks for CentOS Stream, you can utilize the ones available for RHEL 8/9, for all CentOS 8 or newer RHEL 9 clones.

What’s different in openSUSE compared to CentOS?

While many core components are either equal or highly comparable, differences do exist between openSUSE Leap and CentOS. These variances often revolve around more philosophical concepts, such as kernel compilation or distribution installation methods.

In our upcoming blog posts, we’ll explore further into these areas, covering the most relevant differences and their potential impact on migration. We’ll also explore migration tooling, with a special focus on the transformational roles of automation and AI in making migration processes easier and more affordable than ever before.

Summary

We’ve shown you that adopting openSUSE, whether for testing, migration, or as part of a healthy dual-vendor strategy with SUSE and Red Hat, can be less complex than you might think. So why not give it a try?
