On the other hand, Ubuntu is also a free, open-source community-supported Linux distro based on the Debian architecture. It came first in the market in 2004 with a rich set of features and packages. It’s also highly stable and customizable. CentOS vs Ubuntu server, it seems hard to choose which one is better. Let’s begin.

CentOS vs Ubuntu: Deep Down into the Core

It’s possible when a distro is perfect for someone, but the same distro is not what you’re looking for. So, don’t search for the best. Go with the distro which will be the right one for you. CentOS vs Ubuntu server comparisons can make you confused. So, I’m here with 15 essential facts that will help you choose the perfect distro for you.

1.  System Requirements

Let’s check out the minimum system requirements for both Ubuntu and CentOS. Requirements for CentOS varies with its versions. For example, to control via a graphical user interface (GUI), CentOS 5 requires at least 128 MB free space. At the same time, to operate via command line CentOS 5 requires a minimum 512 MB memory space where CentOS 6 needs at least 392 MB.

Again, CentOS 5 and 6 have requirements of at least 1GB, and CentOS 7 has 2GB memory space requirement overall. CentOS 7 requires minimum 10GB hard disk space, but for better performance 20GB hard disk is recommended.

On the other hand, Ubuntu desktop edition has system requirements of 2GB RAM, 25GB hard disk space and 2 GHz dual-core processor. It also requires 1024×768 screen resolution with VGA capability.

So, we can see that Ubuntu has higher requirements. But, isn’t it obvious? Let’s check other vital facts of CentOS vs Ubuntu.

2.  Installation

The installation process for both CentOS and Ubuntu is straightforward. They use different installers for installation. Redhat Anaconda installer is for CentOS installation. On the contrary, Ubuntu uses its own installer.

With Ubuntu, you just need to have the DVD or USB Flash that already contains the required version of Ubuntu. Then you have to boot your computer using one of them. It’s straightforward even for the beginners who have no such technical knowledge about it.

On the other hand, to install CentOS, first, you have to burn a DVD or USB. CentOS provides the required ISO image to download and write it on the CD-ROM. Everything ISO, Minimal ISO, and DVD ISO; 3 versions are available for CentOS installation. You will get some configuration options to select among them before the installation.

3.  Basic Interface

The most interesting part of CentOS vs Ubuntu is their basic architecture. CentOS is derived from RHEL (Red Hat Enterprise Linux). Meanwhile, Ubuntu is a Debian architecture based free and open-source operating system.

Well, at the beginning of the installation you can choose the Gnome GUI for CentOS as your desktop environment. The desktop contains some default icons at its left side. You can change their places to anywhere on the desktop.

With Gnome, you’re going to have a desktop with two panels or bars. The bottom bar contains the running applications’ icon. And the top panel contains buttons for applications and places, and it also shows the icon of running applications on your computer.

You can install Ubuntu with Gnome desktop environment too. It comes with two panels on your desktop. The top panel or bar contains notifications and running app windows. The left bar is kind of a dock type panel. It contains important active applications. You can move it to the top or bottom.

4.  CentOS vs Ubuntu Performance

It’s hard to get a conclusion on CentOS vs Ubuntu performance. Both of them are highly stable, reliable, and faster. The better your hardware, the faster they will perform. Actually, the performance depends on the configuration. If you can configure them accurately, they will give you their best.


It doesn’t matter what you’re using between CentOS vs Ubuntu; you should make sure that you secure them properly. To get better performance, it’s a must. Ubuntu comes with frequent updates, user-friendly interface, leading edge, and feature richness.

On the other side, CentOS doesn’t provide frequent updates and also it’s not rich in features. But it’s lightweight and highly trusted. CentOS actually is more secure than Ubuntu.

5.  Software Manager

CentOS vs Ubuntu server, both have their own software management system. The important thing is they have entirely different backgrounds or architectures. CentOS is derived from Red Hat, and at the same time, Ubuntu has directly come from Debian. That’s the reason why they have different software managers.

On the other hand, the software management system of RHEL is RPM (Redhat Package Manager). But CentOS can’t directly use it. First, it has to download and install RPM packages via yum from the central repository.

All distributions based on Debian have a standard package management system called Apt. Apt is the Advanced Package Tool. So, Ubuntu uses Apt to manage its software packages. It’s a very powerful software management tool. You can also use the apt-get package manager to download DEB packages. It’s also capable of handling version upgrades.

6.  Software Sources with Useful Options

Ubuntu and CentOS, both have software resources, and all of them are compatible with the respective system. You’ll get different software packages there available for download and install with the latest versions.

It will surprise you that there are more than 40,000 applications are available at Ubuntu’s software center. Unbelievably, Ubuntu comes with huge repositories. And, of course, this feature attracts different types of users amazingly.

Meanwhile, CentOS software source has limited repositories such as CentOS Extras, CR, CentOS-Fasttrack, Software Collections, CentOSPlus, and more. Only CentOS-Extras is by default enabled. You can enable other repositories to use them. It may not provide thousands of packages like Ubuntu, but it has what you need. Both CentOS and Ubuntu have third-party repositories. So, CentOS vs Ubuntu, who wins this fact?

7.  Necessary Software Out of the Box

It’s very common and obvious that users generally expect some applications in the system by default or pre-installed as soon as they installed the distro. Every single operating system has some application by default like web-browser, calendar, and media player, so do Ubuntu and CentOS. And, the interesting part is you can change those default applications anytime.  

Both the distros have Mozilla Firefox and Videos in common. Besides, Ubuntu has Thunderbird Mail for mailing, Rhythmbox for music, and Image viewer for images. With Gnome desktop environment, Cents comes with Cheese and a set of LibreOffice Tools. Moreover, Ubuntu comes with a massive application package compatible with Ubuntu.

8. CentOS vs Ubuntu: Beautification of GUI

CentOS vs Ubuntu, which one comes with better GUI? Well, according to the graphical user interface (GUI), Ubuntu and CentOS need one same tool, and that is the Gnome Tweak Tool. If the desktop environment on both the operating systems is Gnome, it handles the customization in almost the same way.

With CentOS, you can get different options with the appearance of desktop, workspaces and other settings. You can customize them using the Gnome Tweak Tool. It comes with different attractive designs and themes.

With Ubuntu, you will find many icons and themes for your desktop in the Gnome world. You need to add the Gnome shell extension to your browser. Then you can download and install extensions for theme and icon customization. The Ubuntu Gnome Tweak Tool will give you the options for customization.

9.  System Customization

Both CentOS and Ubuntu come with fantastic customization options. You can go to the system settings and there you will get options to customize your computer. You can customize the appearance, brightness and look, language support, color, Bluetooth, display, and some other settings.

You already know that you can customize from Gnome Tweak Tool in CentOS. And, with Ubuntu, you can use Ubuntu Gnome Tweak Tool to customize your computer. So, the CentOS vs Ubuntu performance is getting more interesting, isn’t it?

10.  Various Desktop Environments

According to the desktop environments, Ubuntu wins the battle of CentOS vs Ubuntu. Well, both distros come with the support of different desktop environment on them. For example, you can use a desktop environment like Gnome, KDE, MATE, Cinnamon, and XFCE on the CentOS operating system.


You already get Gnome and KDE GUI directly with CentOS. You just need to confirm which GUI you want to choose before installation. You can download and install other Desktop environments via yum command.

At the same time, Ubuntu provides support for Gnome, Budgie, XFCE, LXDE, KDE Plasma, and MATE as well. Among these environments, Gnome is the default GUI that comes with Ubuntu.

11.  Software Update and System Upgrade

Let’s check out who wins the CentOS vs Ubuntu performance battle. For the software update and system upgrade, both CentOS and Ubuntu have their own specific way and system. With CentOS, users have to check for an update manually via yum (Yellowdog Update Manager) command. If there’s an update, you can install it manually via yum command. It’s a must to write the correct command line.  

Meanwhile, to check the most recent update of any app, Ubuntu has a software update utility tool. It can check any update faster than CentOS. You can update your apps from here.

So, basically, it’s easier to update software or upgrade the entire system with Ubuntu. Then it’s clear that Ubuntu is the winner of the CentOS vs Ubuntu performance battle in case of update and upgrade.

12.  Release Cycle

CentOS and Ubuntu have a different release cycle. Well, CentOS doesn’t have any exact release cycle overall. The whole new version comes after one to four years just after the release of the respective RHEL version. It takes a few months to arrive an update for any version. They don’t have a fixed period, but they have long time support.

On the other hand, Ubuntu has its frequent update release cycles. After every six months, they release an update with free support, though this support is for a short time. Every fifth release comes with long-term support.

13.  CentOS vs Ubuntu Performance: Corporate or Business Use

Well, you can use both CentOS and Ubuntu for corporate server or business website or web hosting. But, with CentOS, you get more advantages with its high performance. I’m not sharing my opinion. People are sharing their experiences. According to them, CentOS is better to choose from CentOS vs Ubuntu Performance argument.

CentOS-vs-Ubuntu - Corporate or Business use

You already know that CentOS doesn’t offer frequent updates. The reason behind this feature is every time the CentOS developers develop a new version or update; it takes a very long time to test it. That’s how whenever they release a new version it’s more secure and stable. Besides, most of the control panels provide supports only for CentOS.

So, in case of handling a lot of clients and control panel in web hosting, CentOS would be better than Ubuntu.

14.  Gaming Experience

Undoubtedly, Ubuntu wins the CentOS vs Ubuntu performance fight according to the gaming experience. Of course, you have to choose such games those are supported on Ubuntu. Except that, Ubuntu is a better platform for gaming.

Developers really didn’t give priority to play games on CentOS. So, if you’re a true gamer or just play games for fun, Ubuntu should be the better option than CentOS. Its gaming performance will be better.

15.  Community Support

Ubuntu and CentOS, both have their own community support. Ubuntu gets both official support from Ubuntu and corporate support from Canonical. Besides, it gets huge community support, and that’s also free.

Otherwise, Ubuntu is also a great Linux distro. Again, the decision is yours to choose one.

Tell us about your experiences, questions, and suggestions in the comment section below. Don’t forget to share the article if you like it.


  1. I am 12 years Linux system admin, I provide web site services, I use centos for web servers with cpanel.
    In my opinion, For Beginners, For Gamers, For Home and DeskTop use, the UBUNTU is the best Linux distro ever! For a web server like web hosting cpanel/Plesk etc, Centos is the best choice for business – web servers – for companies

  2. Today’s date: 5/3/2020
    I have been a sysadmin for 15 years now and I can tell you from what I’ve seen Ubuntu is the clear choice for desktop as well as enterprise applications. Here’s why:
    – the .deb packaging system is easier to write packages for
    – there are more debian packages than there are rpm packages, easier to find a deb package for an obscure app than it is to find rpm; also apt is more robust than yum; hell, they just took out yum in favor of dnf because yum was just not that good.
    – Ubuntu comes up with latest releases much faster than CentOS. How long did we have to wait for CentOS8, anyone?
    – Ubuntu Bionic works like a charm with Xen, whereas, even today I still can’t get Centos8 to even boot on xen
    – I have not seen any clear evidence that Ubuntu is less stable than CentOS in enterprise use
    After 15 years of fiddling with CentOS honestly I’m tired of how they handle the distro.

  3. Congratulations to Benjamin Tyger and Jason Nichols for actually saying something useful.

    I am rapidly coming to the conclusion that Linux fanbois are chronically inarticulate and have no idea how to explain anything other than they hate whatever you choose, because it is “Stupid”.

    Explain the benefits clearly and illustrate what you say where that helps (most cases).

    The endless uninteresting histories of the convoluted origins from other equally opaque distros do not help.

  4. There are a few important facts this article missed.

    * Ubuntu LTS versions are only supported for 5 years. Redhat / Centos releases are supported for 10 years. Ubuntu gets more frequent version bumps because of the quicker release cycle. This let’s the administrators / users user more contemporary software.

    * Ubuntu LTS supports in-place upgrades. This is an important feature for both home and business desktops. Redhat / CentOS does not support this.

    * CentOS is a derivative distro. While this isn’t alway a bad thing, it can sometimes lead to slower release of security patches.

  5. CentOs and Ubuntu are different beasts designed for completely different markets. Ubuntu is designed from the ground up to be a desktop OS and then they released a server edition as an afterthought. CentOs was designed to be RHEL without a paid-for support contract. It is built specifically for use as a server environment with desktop features added to make system administration easier.

  6. Hi

    I like this articles, its very interesting knowladge for CentOS vs Ubuntu. Currently i am using CentOS for personal and corporate purpose . And also very familier to Ubuntu both are very good platform to manage the infrastructure, now come to the point as i said i am currently using the CentOS, this is more secure to Ubuntu and also web hosting feature . So recommend CentOS is good for any organization.
