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.
They should be identical.
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.
Correct. In addition, I think the CentOS kernels are basically the "AS" kernels, and obviously there is no activation key, nor will you be able to use RHN for errata notification, etc.
My boss is a little concerned about the differences since we host production servers that require minimal downtime.
We typically continue to use RHEL for production stuff, and CentOS for anything non-critical. Not that CentOS wouldn't make a solid production server.
