Ubuntu LTS versions will always come first in the list when someone is looking for a server operating system alternatives to CentOS. Furthermore, Ubuntu OS is considerably easier to use and manage than CentOS. Ubuntu utilizes the “APT” package manager for installing packages in the fastest way. This Linux distribution also offers a large community that provides guides and online tutorials that users may utilize to address various challenges they would probably face while setting it up. Ubuntu releases one LTS version every two years in the software market, while the regular release occurs every six months and has nine-month life support. The latest long-term supported version from Ubuntu is 20.04 LTS Focal Fossa. The developers will keep this Linux distro until 2025 under public license, with a commercial option to extend it to 2030.
Red Hat Enterprise Linux (RHEL)
All enterprise organizations should consider RHEL as one of the top alternative options of CentOS. You should ask what the reason is? Because Red Hat is all about growing your business. It is one of the major contributors to open source projects, with the title of “world highest-earning open source corporations.” RHEL deployment charges a specific cost. You won’t deploy this distribution for free unless you use the No-cost RHEL program for production. This version allows you its deployment to 16 systems or fewer.
Red Hat Enterprise Linux is built on Fedora, a community-driven distribution that acts as a proving ground for features that will make their way into RHEL. RHEL is a subscription-based operating system that offers world-class support. It also provides the facility to go for the self-support subscription at ow cost. RHEL also comes with some of the most comprehensive distribution documentation available. This distribution can serve practically in any environment because it supports IBM System Z, x86/64, ARM, and Power.
Oracle? Yes! You are correct. Isn’t it time to bring out the pitchforks once more? This Linux distribution is binary compatible with RHEL. It is called a “rebuild distro.” Similar to CentOS Linux, Oracle Linux is based on RHEL sources.
Oracle Linux could be your new distro if all your company desires a free-as-in-beer distribution that closely follows RHEL. This distribution has been operating for a long and is backed by one of the world’s largest IT companies. However, switching to Oracle because Red Hat’s governance was arbitrary and authoritarian is an unusual flex. As a replacement for CentOS, Oracle Linuxmakese its place in most organizations because of its significant Oracle presence.
SUSE Linux Enterprise
SUSE Linux Enterprise Server (SLES) is a manageable and flexible platform that lets administrators and developers impose their business-related workloads in the cloud, on-premises, and at the edge. SUSE engineers respond quickly to security problems and provide top-notch security upgrades. SUSE automation functions, auditing, management setup make it simple to ensure that external regulations and internal security policies are followed. This distro also Includes services and APIs that enable developers to create applications that operate with the broadest range of servers, architectures, network options, and storage. SLES is adaptable to any operating environment and migrates workloads between them with ease.
Support for cloud platforms and leading hypervisor technologies is included in every SUSE Linux Enterprise Server subscription. Utilize this Linux distribution to increase your flexibility while lowering your costs without compromising security, performance, or reliability.
Debian Linux is another well-known open-source, strong server distribution. It is also considered one of the most prominent Linux kernel-based operating systems. Because it is an old community-driven distribution, there are numerous internet resources available in the case of any problem. This Linux distribution is also well-known for its extensive architecture support and software library with solid documentation provided by its developers.
CloudLinux developed the AlmaLinux, which is also formerly known as Project Lenix. Each year, the corporation invests $1 million in its one-to-one RHEL 8 compatible version and subsequent releases. AlmaLinux is CloudLinux’s freely available, open-source,community-driven distribution.
This CentOS alternative is already in its second release with version 8.4, which is enterprise-ready and based on RHEL 8.4. According to Jim Jackson, the president and chief sales officer of CloudLinux, one of the essential features of AlmaLinux, particularly for larger organizations, is its ability to acquire enterprise-grade support through TuxCare.
Before Red Hat acquired CentOS in 2014, CentOS had a successful and long history. CentOS was a significant independent Linux server distribution for almost a decade. That was because of its co-founders Rocky McGough and Greg Kurtzer‘s dedication to CentOS. McGough is no longer alive, but Kurtzer has begun a new RHEL/CoreOS derivative named Rocky Linux in his honor.
Rocky Linux will be a freely available, community-based server-oriented Linux distribution, similar to the pre-Red Hat CentOS. Rocky does not yet have a release date, but it does have a lot of buzzes. It was formerly the most popular GitHub repository, and it now has over 650 potential contributors.
