Conclusion: Do you need a system on the server that will last for a long time and you don't want to worry about having to be updated frequently? In this case, Debian is your choice, the system will allow you not to update for a long time, and you will also be able to find answers to your questions on the forums.
CentOS
The third place in popularity with this handsome man. Unfortunately, but it can be safely called outdated (Although many still use it) in the near future, this distribution will cease to be b2b email list so popular because CentOS has turned into a laboratory where new features of this OS are being explored. The support period for this system is very long (about 10 years), but Red Hat Linux stops supporting, for example, CentOS 8 (Discontinued) CentOS 7 in 2024. Next, there will be only CentOS Stream on which updates for Red Hat Enterprise Linux are tested. In short, the system is good, but it doesn't make sense to put it on a new server anymore.
Pros: A large amount of information on the Internet, a long support period (about 10 years)
Cons: This distribution turns into a laboratory for exploring new features, which makes no sense to install on a new server.
the fact that some distributions are coming to an end and CentOS is probably one of them. In this case, you can try to hold out for some more time on it, or else accept the fact that it should leave with dignity and use the new OS.
Conclusion
Linux is one of the most famous operating systems for working both with servers and on a personal computer. This OS is very easy to configure and wide in functionality, which is why many companies, and just users use it with pleasure. As I indicated earlier, each of the distributions (I indicated only the three most popular ones) has its pros and cons, but which one is better?
