Choosing an operating system for the server, desktop, or development environment based on Linux has a few strong contenders – CentOS vs. Ubuntu. While they are both very popular, well-supported, and open-source, they seem to be aimed at a little different audience and, more importantly, different use cases. Let’s get deeper into CentOS vs. Ubuntu by detailing key differences, strengths, and their ideal use cases.
Introduction to CentOS and Ubuntu
What is CentOS?
CentOS is a community enterprise operating system, free for all. It is highly regarded in the industry for being stable and for having all the features which are used in the enterprise environment. Many people love to use this in the server environment. While comparing CentOS vs. Ubuntu, CentOS maintains long-term support with reliability. It is RHEL but not for money.
What is Ubuntu?
Ubuntu is a Debian-based Linux distribution that has been known to be user-friendly, while it also has frequent updates. It has separate versions for desktop and server environments, thus giving room for almost everyone. In the comparison of CentOS vs. Ubuntu, Ubuntu is among the most popular distributions among developers, new users, and those looking for a modern and community-driven Linux experience.
Key Features Comparison
Stability and Updates
CentOS
CentOS is focused on stability rather than feature freshness. Conservative update procedures ensure that there is minimal disturbance in the production environment. Deeply tested updates make it suitable for the server to maintain a high uptime.
Ubuntu
Ubuntu is updated more frequently, and there is a focus on giving the latest features and enhancements. This may be appealing to developers and innovators but may not be stable enough for enterprise use. Ubuntu also has long-term support versions, which will update for up to five years, balancing stability with modernity.
Package Management
CentOS
Centos is a GNU/Linux distribution that uses the RPM system and yum or dnf package manager to update the software. It comes loaded with enterprise-focused software packages but lacks some of the more modern tools and apps by default.
Ubuntu
Ubuntu relies on Debian’s Advanced Package Tool (APT) for the management of software, which is one of the friendliest systems. The Ubuntu repository is huge and normally contains the latest versions of software and developer-friendly tools.
Community and Support
CentOS
CentOS has a relatively small but very dedicated community, with strong support on enterprise and server-specific issues. As it mirrors RHEL, users often refer to RHEL documentation for more information.
Ubuntu
Ubuntu has the largest Linux community, so guides, forums, and solutions for practically any issue are available without much trouble. Canonical also offers support plans to enterprises on a commercial basis, which secures other business needs.
Performance
CentOS
This variant is optimized for business environments and high-performance servers. It is very conservative in its approach to ensure maximum compatibility with enterprise hardware and software. This means often better performance in mission-critical applications.
Ubuntu
Ubuntu runs pretty well on a wide range of hardware and use cases although its focus on usability and new features will tend to consume a bit more resources, especially in the server-based scenario.
Security
CentOS
As CentOS is a spin-off from RHEL, it inherits most of RHEL’s strong security implementation, especially mandatory access control with SELinux (Security-Enhanced Linux). Its updates tend to be more reliable for enterprise environments.
Ubuntu
It is also very secure with AppArmor and always updated security patches. One of the cons of updating so frequently is that the newer vulnerabilities come in as well.
Desktop Experience
CentOS
CentOS is not popularly used for the desktop environment. Its aim is towards stability and has server applications, so it lacks user-friendly features, which other desktop-oriented distributions have.
Ubuntu
Ubuntu shines as a desktop OS, featuring a polished interface (by default, GNOME) and multimedia applications. It is a good OS for beginners to use daily.
Ideal Use Cases
CentOS
- Enterprise servers requiring high stability and long-term support.
- Businesses needing compatibility with RHEL-based software.
- Environments where minimizing updates and ensuring uptime is crucial.
Ubuntu
- Developers who need access to the latest tools and libraries.
- Individuals looking for a user-friendly Linux desktop experience.
- Organizations seeking a flexible system with commercial support options.
Comparison: CentOS vs. Ubuntu
Here’s a comparison table for CentOS vs. Ubuntu.
| Feature | CentOS | Ubuntu |
|---|---|---|
| Base | Red Hat Enterprise Linux (RHEL) | Debian |
| Update Frequency | Infrequent, stability-focused | Frequent, with LTS options |
| Package Manager | RPM (yum/dnf) | APT (apt-get) |
| Community Support | Smaller, enterprise-focused | Large, developer-friendly |
| Security | SELinux | AppArmor |
| Desktop Use | Minimal support | Polished GNOME desktop |
| Target Audience | Enterprises, servers | Developers, general users |
CentOs Stream: A New Chapter in Centos
CentOS has taken up a more rolling-release model which it uses as the testing ground for RHEL. However, this has led to some heated debate in the Linux world because some users view this as compromising the stability that CentOS is synonymous with. Many have shifted their bases to Rocky Linux or AlmaLinux for enterprise-level stability.
Role of Ubuntu in the Linux World
Ubuntu is also winning through frequent updates and features directed to the user. Being flexible, it remains more preferred for personal as well as professional use. With focus on cloud computing and IoT by Canonical, Ubuntu will keep coming relevant with the emergence of different technologies.

The decision between the two will therefore depend on what you need, either the stability and enterprise focus of CentOS or the modern, versatile appeal of Ubuntu. Understanding the differences of CentOS vs. Ubuntu and aligning them with your goals will help make an informed decision that enhances your Linux experience. Both the distributions are community-driven and free, open-source models to ensure a similar consistent experience compared to the former model of CentOS because they both will follow the release schedule of RHEL. There is a focus on why even small disruptions in continuous and reliable Linux distributions, at all costs, are important within enterprises.
FAQs
How do CentOS and Ubuntu update?
CentOS is conservative, with minimal updates that are stability focused. Ubuntu, especially the LTS, is updated regularly for security and software improvements, whereas the non-LTS versions receive cutting-edge updates more often.
Is CentOS still a good choice after the introduction of CentOS Stream?
CentOS Stream has migrated toward a rolling-release model as an upstream testing ground for Red Hat Enterprise Linux. Such has made some users migrate towards using alternatives like Rocky Linux or AlmaLinux for their enterprise-grade stable environments. However, for those who need the preview of RHEL, CentOS Stream is still on the table.
With the release of CentOS Stream, is CentOS still a wise option?
Yes, it’s more stable because CentOS tends to update fewer packages but tests them more deeply. That is why many enterprises use CentOS in an enterprise-grade environment. Ubuntu is updated quite frequently; at times, this results in instability, but long-term support (LTS) does a great job of keeping the system up to date yet still stable.
Which OS is more secure, CentOS or Ubuntu?
They both are secure, but differently. CentOS uses SELinux for mandatory access control while Ubuntu uses AppArmor. They are both supplied with regular security updates.
Is Ubuntu less stable than CentOS?
Yes, because CentOS focuses on fewer, well-tested updates, it is typically viewed as being more stable. It is often used in enterprise-level environments because of its stability. Ubuntu frequently releases updates, which at times causes instability, but their Long-Term Support (LTS) versions strike a fair balance between modernity and reliability.
