Have you ever wondered, “What is Enterprise Linux? What makes a Linux distribution ‘Enterprise’? Are Enterprise distributions better than others?” If so, you’ve come to the right place to find the answers to all these questions.<\/p>\n\n\n\n
The Linux ecosystem is vast, including hundreds of distributions. Although some of the foundations on which the modern Linux world is built, such as Debian<\/a> or Arch<\/a>, are known modestly as just “GNU\/Linux,” others, like RHEL, are considered part of the Enterprise class.<\/p>\n\n\n\n Does this mean that Red Hat Enterprise Linux, for example, is generally superior to Debian? The short answer is ‘no’; the ‘Enterprise’ makes it more suitable and preferred for some use cases. Let’s first look at what qualifies a distribution as an Enterprise class.<\/p>\n\n\n\n A Linux distribution is considered ‘Enterprise’ based on several key features and qualities that align with the business environment needs<\/strong>, particularly in support, security, and reliability<\/strong>. Here are the primary factors that make a Linux distro suitable for enterprise use:<\/p>\n\n\n\n The most important feature of an Enterprise Linux distro is the availability of professional, commercial support from the vendor.<\/strong> This support can include 24\/7 troubleshooting, technical guidance, and help with system maintenance, which is essential for businesses that rely on their Linux environment for critical operations.<\/p>\n\n\n\n Enterprise Linux distributions typically offer long-term support versions, which receive security updates, bug fixes, and system enhancements for extended periods (often 5-10 years). This stability is crucial for businesses that need consistent, reliable performance without frequent system upgrades.<\/p>\n\n\n\n Enterprise Linux distributions ensure compatibility and support for various hardware platforms and enterprise software. This includes extensive testing to ensure the distro works well with common enterprise hardware, databases, and applications.<\/p>\n\n\n\n Last but not least, Enterprise distributions often undergo certification processes to comply with various industry standards, such as FIPS 140-2 for cryptographic modules, Common Criteria EAL (Evaluation Assurance Level), and others. These certifications are important for businesses in regulated industries.<\/p>\n\n\n\n From what has been said above, it is clear that Enterprise Linux distributions are specifically designed to meet the needs of business users, where reliability and the possibility of timely and professional support are top priorities.<\/p>\n\n\n\n Additionally, it is essential to understand that when discussing Enterprise Linux, we are talking about a well-established business model<\/strong>. The profits are generated not so much from the distribution itself, which is usually freely available, but from the additional services offered with it.<\/p>\n\n\n\n Let’s now explore some of the leading Enterprise Linux options businesses favor.<\/p>\n\n\n\n RHEL<\/a> has been a leading name in Enterprise Linux for over two decades. Since its initial release in February 2000, after the previous free-to-use Red Hat Linux phase-out, RHEL wrote the history of paid Linux services, proving that open source can also be a profitable business model. Currently, it is the most widely used Enterprise Linux distribution.<\/p>\n\n\n\n SUSE Linux Enterprise is the other name with the longest track record in the Enterprise Linux field. It offers two commercial versions: SLES<\/a> (the server edition) and SLED<\/a> (the desktop edition). However, over the years, the company has somehow always remained in the shadow of RHEL, which has dominated this sector. It is gratifying, however, that SUSE has risen sharply in popularity in recent years, making it an equal competitor to Red Hat.<\/p>\n\n\n\n With its introduction in 2004, Ubuntu<\/a> revolutionized what Linux could offer as a desktop operating system to the average home user. Over time, Canonical, the company behind Ubuntu, has expanded its focus to include business users. Today, they provide various paid subscriptions<\/a> and extended support<\/a> for their desktop and server Ubuntu LTS releases, making it a preferred option for many businesses.<\/p>\n\n\n\n We put Alma<\/a> and Rocky<\/a> together because they were both emerged around the same time as a response to Red Hat’s decision to phase out CentOS as a server platform. Both are built on RHEL source code, but that alone is not enough to be considered Enterprise. To fall into this category, both provide paid support services through their associated companies, with TuxCare<\/a> on the Alma side and CIQ<\/a> on the Rocky side.<\/p>\n\n\n\nWhat Makes a Linux Distribution \u2018Enterprise\u2019?<\/h2>\n\n\n\n
