The difference between CentOS and Redhat Linux

There are two ways in which RHEL is released. One is the binary distribution method, the other is the source code distribution mode.

Either way, you can get it for free (for example, download it from the Internet) and publish it again. But if you use their online upgrades (including patches) or consulting services, you'll have to pay.

Rhel has always provided the source code for the distribution, CentOS is the source of the RHEL release from the new compilation, the formation of a binary version can be used. Since the source code for LINUX is GNU, it is legal to get the source code from RHEL to the new binary. Just REDHAT is a trademark, so you have to remove REDHAT's trademark in the new release.

REDHAT's attitude to this distribution is: "We are not really against this distribution, the users who really pay us, they value not the system itself, but the business services we provide." ”

So, CentOS can get all the features of RHEL, even better software. However, CentOS does not provide commercial support to users and, of course, is not responsible for any business.

I'm gradually transferring my rhel to CentOS because I don't want to pay for Rhel upgrades. Of course, this is because I've had years of experience with UNIX, so it doesn't matter to me that RHEL's business support is there.

But if you are a purely business-oriented enterprise, then I suggest you buy the RHEL software and purchase the corresponding services. This will save you money on IT management and get professional services.

In a word, the choice of CentOS or RHEL depends on whether your company has the appropriate technical force.
