Businesses and developers often debate between CentOS vs Ubuntu when selecting an operating system for their servers. But with CentOS Stream replacing the previous CentOS Linux, the discussion has changed dramatically in recent years.
The previous CentOS Linux, which many server admins used, is no longer available. Today, the CentOS project concentrates on CentOS Stream, which sits upstream of Red Hat Enterprise Linux (RHEL).
Ubuntu, in contrast, continues to deliver regular updates and long-term support versions such as Ubuntu 26.04 LTS. That implies that the old comparison between CentOS Linux vs Ubuntu is no longer enough.
This amazing guide covers the modern CentOS Stream vs Ubuntu comparison and helps you determine which solution is better for your server in 2026. Is it CentOS or Ubuntu?
CentOS vs Ubuntu: Quick Comparison
Before comparing technical specifics, it’s useful to understand how CentOS vs Ubuntu Server differ in terms of release models, package ecosystems, and common server use cases. The table below gives a quick overview of the key Ubuntu vs CentOS differences.
| Feature | CentOS Stream | Ubuntu Server |

Ubuntu releases new releases every six months and LTS releases every two years on a consistent schedule. Released in April 2026, Ubuntu 26.04 LTS will get regular security updates until May 2031.
CentOS Stream is different. The CentOS Project touts it as a continually supplied distribution that is slightly ahead of Red Hat Enterprise Linux. CentOS Stream 10 is the current main generation for 2026.
What is CentOS?
CentOS Linux was a free Linux distribution based on Red Hat Enterprise Linux (RHEL).
For many years, it was a popular alternative for production Linux servers since it offered a reliable environment similar to RHEL but did not require the same commercial subscription.
However, the initial CentOS Linux project was canceled.
CentOS Linux 8 reached the end of its life cycle earlier than intended, in December 2021. The team then shifted emphasis to CentOS Stream.
CentOS Linux vs CentOS Stream
This difference is very important when comparing CentOS vs Ubuntu Server.
CentOS Linux was a step below Red Hat Enterprise Linux. Changes were initially implemented in RHEL before making their way into CentOS.
On the other hand, CentOS Stream operates in the other direction. It is upstream of RHEL; therefore, modifications can arrive in CentOS Stream before being incorporated in a future RHEL release.
This makes CentOS Stream handy for the following:
- Testing the planned RHEL improvements
- Developing RHEL-compatible applications
- Working inside the Red Hat environment
- Preparing software for future RHEL releases
CentOS Stream, on the other hand, is not a direct substitute for the previous CentOS Linux for those seeking a stable, conventional production server operating system.
Teams searching for such an environment frequently prefer AlmaLinux or Rocky Linux instead.
What is Ubuntu?
Ubuntu is a Debian-based Linux distribution maintained by Canonical. Ubuntu is offered for servers in both regular and LTS releases.
Regular Ubuntu server releases are available every six months and have a shorter support duration.
Ubuntu LTS, or Long Term Support, is published every two years and includes five years of baseline security and maintenance updates.
This makes Ubuntu LTS especially beneficial for servers, as enterprises do not have to execute large operating system updates every few months.
Ubuntu Server is popular for:
- Websites
- VPS Hosting
- Cloud servers
- Package repositories
- Application servers
- Databases
- Development Environments
- Docker and Kubernetes
- DevOps workloads
Ubuntu also provides significant documentation and community help.

CentOS vs Ubuntu: Key Differences
The primary difference between CentOS and Ubuntu is more than just the desktop look or a few commands.
The distributions originate from various ecosystems, utilize different package systems, adhere to different release philosophies, and take diverse approaches to security and management. Here are the detailed CentOS vs Ubuntu for server differences:
1. System Basis and Architecture
CentOS Stream is part of the Red Hat family.
That is, administrators working in enterprise Linux settings will recognize ideas, tools, package formats, and administrative methods shared by CentOS Stream and Red Hat Enterprise Linux.
On the other hand, Ubuntu belongs to the Debian family.
Ubuntu is an obvious next step for administrators who are already familiar with Debian. This distinction becomes significant when an application vendor officially supports just one Linux family.
The best CentOS vs Ubuntu for developers generally relies on the software stack they need to build and deliver.
2. Release Cycle and Stability
One of the most notable CentOS vs Ubuntu differences is the release model.
CentOS Stream uses a rolling-preview approach. It receives updates that are expected to appear in future RHEL releases.
This can be beneficial for testing and development, but it is different from the stable release model that old CentOS Linux users were familiar with.
On the other hand, Ubuntu LTS provides a more predictable approach for production dedicated servers.
An LTS release receives at least five years of standard security and maintenance updates.
For businesses that want a server OS that can run for years with a predictable support period, Ubuntu LTS is often the simpler choice.
3. Package Management
One of the most visible CentOS vs Ubuntu package manager differences is the package ecosystem.
- CentOS Stream manages packages using RPM and DNF.
- Ubuntu makes use of both DEB and APT packages.
Administrators soon grow familiar with any system; however, command and package names may differ.
For example, a server administrator migrating from Ubuntu to CentOS Stream will need to modify familiar package installation, repository, update, and troubleshooting procedures.
Neither system is fundamentally superior. The superior option is generally one that your staff is already familiar with or that your software provider requires.
4. Software and Repositories
Ubuntu has a huge software ecosystem.
Its repositories include several programs for:
- Web Servers
- Programming Languages
- Development Tools
Topics covered include databases, containers, monitoring, networking, and security.
Ubuntu’s repository structure also makes it simple to install many popular apps without having to hunt for packages actively.
On the other hand, CentOS Stream makes use of repositories created specifically for the RHEL environment.
Some extra applications may require EPEL (Extra Packages for Enterprise Linux), or another third-party repository.
For firms that currently use RHEL-based software, this can be advantageous.
Before deciding between CentOS vs Ubuntu stability, review the specified requirements for your control panel, applications, databases, Linux monitoring tools, and security software.
5. Performance and Resource Usage
There is no clear victor in CentOS vs Ubuntu performance.
The workload, CPU, RAM, storage, kernel configuration, installed services, network circumstances, and application architecture all influence a server’s performance.
A weakly designed Ubuntu server can outperform a badly configured CentOS Stream server, yet a meticulously optimized CentOS system can run quite well.
For a web server, PHP setup, database optimization, cache, SSD or NVMe storage, and Apache or Nginx configuration might be more important than the distribution itself.
6. Security and Updates
CentOS Stream runs SELinux, or Security-Enhanced Linux. SELinux is a popular access control mechanism in the RHEL environment. It is powerful, but beginner administrators may require some time to understand and configure it properly for better system administration.
On the other hand, Ubuntu employs AppArmor. Therefore, the debate around CentOS vs Ubuntu security should not be confined to determining which is more secure.
AppArmor also provides extra security controls but is often easier for many admins to grasp.
Both operating systems receive security upgrades.
The biggest distinction is their release and update models. Ubuntu LTS includes a clearly defined long-term security support horizon, which can make planning easier for production systems.
7. Ease of Use and Administration
Ubuntu is frequently seen as easy for newbies because of the abundance of documentation, tutorials, community discussion, and troubleshooting resources accessible online. That makes CentOS vs Ubuntu for beginners a relatively easy decision. Moreover, Ubuntu is typically a more approachable starting point.
On the other hand, CentOS Stream might be a great option for administrators who are already familiar with RHEL-style systems, DNF, SELinux, and corporate Linux management.
For experienced system administrators, the learning curve is less important because both platforms provide sophisticated command-line tools.

8. Community, Documentation, and Support
Ubuntu has a sizable global Linux community.
Canonical also offers commercial support to enterprises that want expert assistance.
The Ubuntu documentation includes many typical server setups, making it easy for administrators to locate answers.
Red Hat supports CentOS Stream, which has a vibrant community.
Businesses who seek a robust, RHEL-compatible operating system akin to the previous CentOS Linux frequently consider AlmaLinux and Rocky Linux instead.
9. Software and Control Panel Compatibility
This is especially relevant when comparing CentOS vs Ubuntu for web hosting or CentOS vs Ubuntu for VPS hosting.
Before you choose an operating system, be sure your desired hosting control panel supports it.
The same goes for:
- Apache
- Nginx
- PHP
- Managed MySQL or Managed MariaDB
- DNS services
- Mail services
- Backup software
- Security tools
A server may be technologically capable of running an application but still be a bad choice if your web hosting provider does not legally support that combination.
