Hi all,
I would like to first preface this e-mail by saying if this topic has
been covered already, could someone point me to the month of the
discussion and I will gladly read it.
We have been using RHEL 3 / 4 in our environment and I am very happy and
satisfied with the stability of the OS. Now with the new technologies
incorporated into RHEL5, specifically Virtualization, Clustering, and
Storage, and the costs associated with them, I was wondering how similar
CentOS and RHEL 5 were.
It is my understanding that CentOS is RHEL 5 with the RedHat icons
removed but the functionality of the packages is the same. In addition,
updates may come a day or two later than RHEL 5.
My boss is a little concerned about the differences since we host
production servers that require minimal downtime.
Any thoughts and opinions are very welcome.
The choice comes down to this;
If you require to have a support contract, and a live person on the other end
of the telephone when you have problems -- Use RedHat's offering and pay the
support.
If you are willing to test things on non-production servers, and use public
resources to work through problems -- Use CentOS. The money you save on
support costs will more than offset the cost of a few test systems to run
updates through.
CentOS uses the same system and source files that RHEL uses, and it is
probably the distribution that is closest to the RHEL offering -- sometimes
too close, because if it is broken on RedHat, it will probably be broken on
CentOS also. The CentOS maintainers also have had success finding bugs and
proposing fixes to the RHEL bug system, which benefits all.
There are many commercial ventures running on CentOS and other similar works.
