CentOS vs Ubuntu: Which Linux Distribution is Right for You?

CentOS vs Ubuntu: Which Linux Distribution is Right for You?

When it comes to choosing a Linux distribution (distro) for your server or desktop, CentOS and Ubuntu are two of the most popular options. Both of these operating systems are based on Linux, and they share many similarities, but they also have key differences. Understanding these differences is crucial when deciding which one to use, especially for tasks like web hosting, software development, or general use. In this article, we will learn Difference CentOS vs Ubuntu, compare their features, advantages, and drawbacks, and help you choose the best one based on your needs.

What is CentOS ?

CentOS, short for Community ENTerprise Operating System, is an open-source, community-driven Linux distribution that is based on Red Hat Enterprise Linux (RHEL). RHEL is a commercial Linux distro aimed at large enterprises, and CentOS provides a free version of it with all the same core features but without any of the commercial support.

CentOS is known for its stability and is widely used for server environments. It is considered a reliable choice for businesses that require long-term support and minimal changes to the operating system. CentOS is typically preferred for applications that require high availability and performance.

What Is Ubuntu?

Ubuntu is another popular Linux distribution, developed by Canonical Ltd. It is based on Debian, another well-known Linux distro. Unlike CentOS, which aims at enterprises, Ubuntu has been designed to be easy to use for both beginners and experienced users. It is widely used in both server and desktop environments.

Ubuntu is known for its user-friendly interface and is often the first choice for those new to Linux. It is updated more frequently than CentOS, with new versions being released every six months, and it also provides long-term support (LTS) versions for five years.

CentOS vs Ubuntu: Key Differences

Base and Origin

  • CentOS: Based on Red Hat Enterprise Linux (RHEL). It takes the RHEL source code, removes all the branding and trademarks, and offers it for free. This means CentOS is essentially a free version of RHEL, which is a paid and commercially supported distro.
  • Ubuntu: Based on Debian. Canonical, the company behind Ubuntu, takes the stable Debian codebase and makes it more user-friendly. It also has a regular release cycle and offers both desktop and server editions.

Package Management System

  • CentOS: Uses the RPM (Red Hat Package Manager) format for package management. The tool used to manage packages is YUM (Yellowdog Updater, Modified), although newer versions have switched to DNF (Dandified YUM). RPM-based distros tend to use .rpm files for software packages.
  • Ubuntu: Uses the DEB format, and its package management tool is APT (Advanced Packaging Tool). Ubuntu users install software with commands like apt-get or apt install. .deb packages are used in Ubuntu.

Release Cycle and Updates

  • CentOS: CentOS follows the release cycle of Red Hat Enterprise Linux (RHEL). It’s a conservative release model, focusing on stability rather than frequent updates. New CentOS versions are usually released every few years, with updates available for many years after that.
  • Ubuntu: Ubuntu has a faster release cycle. New versions of Ubuntu are released every six months, with Long-Term Support (LTS) releases every two years. LTS releases are supported for five years with updates and security patches. This makes Ubuntu a good choice for both developers and those who prefer to work with the latest software.

Target Audience

  • CentOS: CentOS is aimed at enterprise environments and server usage. Its stability and long-term support make it ideal for production servers, where security and uptime are crucial. It’s often chosen for applications like web hosting, database management, and running critical business services.
  • Ubuntu: Ubuntu is aimed at both desktop users and servers. It’s particularly popular with developers and new Linux users due to its user-friendly interface and extensive documentation. While it’s also used in enterprises, its regular updates and ease of use make it a good choice for personal computers and development environments as well.

Desktop Experience

  • CentOS: CentOS isn’t typically used for desktop environments, though it can be installed with a GUI (Graphical User Interface) if needed. It focuses more on server use, so the desktop experience is not as polished or popular as other distributions like Ubuntu or Linux Mint.
  • Ubuntu: Ubuntu shines in terms of the desktop experience. It provides an easy-to-use GUI with its default desktop environment called GNOME. It’s well-suited for personal computers, with an active community offering software, themes, and customization options. If you’re new to Linux and want a good desktop experience, Ubuntu is a great choice.

Community and Support

  • CentOS: CentOS has a strong community of enterprise users, and while it doesn’t offer commercial support, it has a large amount of documentation, forums, and user groups that can help. If you’re looking for professional support, you would need to move to RHEL.
  • Ubuntu: Ubuntu has a large and diverse community, ranging from beginners to professionals. Canonical, the company behind Ubuntu, also offers professional support for Ubuntu Server users. The community is very active, and there is plenty of online help available through forums, wikis, and other resources.

Software Availability

  • CentOS: Because CentOS is closely related to RHEL, it focuses more on enterprise-grade software. It may not have the latest software packages compared to Ubuntu, as CentOS prioritizes stability over having the newest software. You might have to rely on third-party repositories to get newer software.
  • Ubuntu: Ubuntu is often faster in including the latest software. It has a vast repository of packages and frequently updates them. Additionally, Ubuntu has access to Snap packages, which can make installing applications even easier.

Security

  • CentOS: CentOS benefits from the security features of RHEL, which has a strong reputation for security in enterprise environments. CentOS receives regular security patches, but because of the slower release cycle, some security updates may not be as quick as in other distros.
  • Ubuntu: Ubuntu also has strong security measures in place. Canonical’s dedicated security team provides regular patches and updates. Ubuntu’s software is well-vetted and its LTS releases are particularly known for being secure.
