Before we begin shedding light on the differences between the two well-matched opponents, let’s first look at brief overviews.
CentOS is an open-source Linux distribution. Many refer to it as a replica of the Red Hat Enterprise Linux (RHEL), which is considered to be the most widely used in the corporate IT world. CentOS is an enterprise class operating system supported by the community and released back in 2004.
Close similarity to RHEL gives you the luxury to develop in a dominant and one of the best Linux distribution out there. One might say that this already gives CentOS a lead over Ubuntu.
It’s highly customizable, secure, and stable, which is also something to appreciate it for. The close link to RHEL allowed CentOS to have quite a few corporate-level security updates thus making it a safe choice for every user.
Based on the Debian architecture, Ubuntu has been a hot favorite for personal and professional use since its initial release in 2004. It is open-source and gets frequent updates to remove any identified bugs. It is laden with a rich set of package groups and features that are capable of meeting the requirements of any project.
Ubuntu comes with a ton of apps. The Ubuntu software center has over 40,000 applications available! Moreover, the operating system is highly customizable and has top-notch security features.
CentOS vs Ubuntu – Main Differences
Now then, let’s take a look at the differences between Ubuntu and CentOS:
- The biggest difference between the two Linux distributions is that Ubuntu is based on the Debian architecture while CentOS is forked from Red Hat Enterprise Linux.
- In Ubuntu, you can download DEB packages using the apt-get package manager. Meanwhile, in CentOS, you have to use the yum command to download and install RPM packages from the central repository.
- CentOS is considered to be a more stable distribution compared to Ubuntu. Mainly because package updates are less frequent. This can also prove to be a disadvantage of CentOS. If you want the latest version of a certain application or software, you will have to install them manually.
- Ubuntu certainly has the upper hand when it comes to tutorials, online communities, and books. Finding solutions to Ubuntu problems are a lot easier than in CentOS due to its fairly smaller community and lesser available documentation.
- Ubuntu server has a great deal of support for container and cloud deployments which makes it superior to CentOS in this domain.
- If you are a beginner, running CentOS on your server may be a bit harder since RHEL based desktop distributions aren’t widely used. On the other hand, Ubuntu desktop is quite famous and if you have used it in the past, then getting acquainted with an Ubuntu VPS server won’t take long.
- If you want to use control panels to offer web hosting services then you should go for CentOS as it offers the compatibility that you would want. Web hosting control panels like cPanel has always focused on CentOS and other RHEL derivatives. On the other hand, Ubuntu doesn’t support cPanel but has quite a few alternatives, such as Webmin/Virtualmin or VestaCP.
- If you are a beginner: Go with Ubuntu because it has a larger community, a larger reservoir of free tutorials and a lot more frequent updates to help you stay up to date. Also, if you have used Ubuntu desktop in the past then you will not find any real learning curve while starting with an Ubuntu VPS server. CentOS is a viable choice as well but it might present a few learning obstacles in the start if you are a novice.
- If you are a business owner: CentOS is the ideal choice between the two if you run a business because it’s (arguably) securer and more stable than Ubuntu, owing to the lesser frequency of its updates. Ubuntu has its pros as well but there can be scenarios where you have to revert to older versions because of a new buggy update. Additionally, CentOS also comes with support for cPanel, which is something that Ubuntu lacks.
