You always go for the best, Why would you sacrifice on the OS part. Whenever you buy a laptop or even a smartphone, first you decide the OS you want. In smartphones, you might look for Android or iOS. In Laptop/Computer, You might look for Windows or Mac. According to your choice and preference, you select the OS first and then look for the devices available. The same is the scenario with the OS on the Web Server.

Before we begin to compare both of these OS, you need to have a look at the overview of both. This might give you an idea at first, how generic is the OS or the relevance of it.

A Quick Look

Firstly, you need to take a quick look at both of these Operating Systems. We are sharing some of the main details and information about both of these. These are just to make things clear in your mind about the two. After this, you get to see the detailed analysis of them both.


Talking about Ubuntu, It is one of the most widely used Linux Distribution. It is based on Debian Linux. Most of the developers and programmers prefer Ubuntu as their primary Linux Distribution. This is an Open Source project. Ubuntu gets quick updates and even frequently gets the fixes to bugs.

Additionally, You are relaxed about Security while using Ubuntu. You can customize this Operating System as much as you want. It is definitely one of the easiest to use Linux distributions available so far.


CentOS is also an Open Source project. Although, It is based on Red Hat Enterprise Linux (RHEL). It was released in 2004. It is a fact that RHEL is the most widely used Linux Distribution in the IT corporate and CentOS is based on the same. Eventually, CentOS is following the footsteps and is a good Linux Distribution in the IT corporate sector.

As it is closely focusing on RHEL, it clearly makes it a uniquely different OS from Ubuntu. Talking about features, it is also highly customizable too. Even this OS is secure and stable that makes it a good choice for some. The security measures are according to RHEL, which makes it secure enough to take a lead over Ubuntu specifically.

Now comes the part where we are going to compare and contrast the features from CentOS and Ubuntu. You are going to see a lot of different features that matter the most and they are going to collectively help you for choosing the right one.

As we already have mentioned, everything depends on your use case scenario. Both Operating systems are good in their respective areas. All you have to see is what is the most important thing that matters to you. So, check all of the features that you want and see which one is a clear winner among both.

Basic Architecture

Ubuntu is based on Debian architecture while CentOS is based upon Red Hat Enterprise Linux (RHEL). Both of them are good in their area of speciality. So, they both use different package managers that might affect the workload or apps that you would like to use.

While Ubuntu is using the apt package manager and accepts the installation from .deb packages only. Whereas CentOS is using the yum package manager and accepts the installation from .rpm packages. 

But, it is an important thing to note that you cannot install .rpm package on Ubuntu or .deb package on CentOS. Clearly, this makes you check about the packages available for the OS you are going to select.

Security & Stability

If this is what matters to you, We’ve got you covered. Just to let you know, Ubuntu provides frequent updates as compared to CentOS. You get to see a new version release every six months from Ubuntu. You might see various software that are available with every new update on Ubuntu. There are a lot of things that Ubuntu takes care of when it comes to updates.

But with the new and frequent updates, your existing software might end up creating a mess. As the configuration might need some changes while the regular and frequent updates offer the latest technology and features.

Whereas CentOS does not provide frequent updates. Rather, It takes more time to include features in the release and update it. As the developer team in CentOS is smaller than Ubuntu. Although you see fewer updates on CentOS but they are supported for 10 years from the date of release instead of 5 years on Ubuntu.

Software and Apps

While you are talking about the number of Software on both of these, Ubuntu is a clear winner for that. There are definitely more software available on Ubuntu as compared to CentOS. You might need different functionality on your web server, the software is a thing that you will require for that.

You might have heard of cPanel. The software is written for Red-Hat based systems. If you see the quality software, CentOS might win. There are different software available that are used widely and are based on Red-Hat systems or specifically CentOS in this case. So, You definitely need to check which are the software that you are going to use on your webserver.

Support and Forums

If you mess up something, you need someone who can take care of the problem. Support comes handy whenever you face any issue or find a bug. Ubuntu has a great number of active users on the forum, they will answer your query if its an easy or common one. 

Although you might not get a solution to all your problems through the forum, you will require the support to take action. But, Ubuntu has premium support that means you need to pay some amount of money for such issues. As Ubuntu provides frequent updates, it is generally not practical to solve all the queries raised by direct consumers, testers, beta users & more.

Easy to Use

You always look for the thing that is easy to use. When it comes to the Operating System, why would someone take a chance? There are different things that make the Operating system easy to use. The experience should be great enough so that the user would like to use the Operating System more.

The OS should act as a familiar thing to the user. The user should not look for the documentation or over the web for small things on the operating system. All the important functions should be easily accessible on an operating system. 

Ubuntu is the operating system that cares for the user experience. There are more numbers of guides, tutorials available for Ubuntu as compared to the CentOS. That clearly makes a valid point for the comparison. Where CentOS presumes that the user knows about the basic commands of an OS like Sudo or other commands, Ubuntu is the opposite.

If you are an advanced user in the area of the Operating system, prefer CentOS. But if you don’t know about the commands that are the most basic and common, prefer Ubuntu. It will be easier for you to understand things on Ubuntu than CentOS.

Comparison Based on Use

If you are a beginner

You need a good amount of tutorials and guides in order to use OS with commands. You definitely need frequent updates that will provide you enough features that you can test and deploy for your servers. You need people who understand you, through the forums. Ubuntu is popular amongst the developers though.

You will not find any difficulty while trying Ubuntu even for the first time. With the number of updates, easy to use interface, tutorials, and guides, Ubuntu is what you deserve. Although, CentOS is not bad at all if you want to try as a beginner, but it might take some time for you to learn the things.

Also, there are reasons for you to not focus on stability. As in the initial stage, you can bear with some bugs at the cost of frequent updates and more features. 

If you are Advanced User / Business

What matters for you is the stability and the features that are already existing for your work. You can easily cross-check the things that are already existing on the Operating system before choosing. You need to make sure that your data is secure enough and the system is stable. Even if you don’t get frequent updates, you rely on existing ones. Although, CentOS provides updates in greater numbers but not too frequently. 

One of the most important things that you need to know, CentOS is based on RHEL. Most of the useful software is available on CentOS only. Like software that you might have heard of, cPanel is made for Red-Hat oriented OS. CentOS is one of the most stable and secure OS compared to others (that doesn’t mean Ubuntu is not secure or stable enough).

All you have to check is the software you are going to use for your business. Otherwise, CentOS will provide more stability and a lesser number of updates are good at some point when it comes to user experience.

Final Call

The final call is yours. What we could do is tell you about the things that mattered about both of these. You have to check your use case scenario and see which one will suit you. If you don’t know anything about the use case and you are trying for the first time, Go with Ubuntu. You will get more features and software available on Ubuntu as compared to CentOS.

If you are concerned about the data on your server and want to provide a good user experience to the audience, prefer CentOS. 

Let’s Conclude

Everything is up to you and your use case. Both of the operating systems are good enough to perform in the longer run. You can definitely rely on any of the Operating Systems for your Web Server. There are many things that you might have to look into the operating system apart from what we have shared. You can anytime look for the features from any of them.
