* OS Kernel / Security / OS Patches upgradation & Vulnerability fix is available ?

* Upgrade the latest release CentOS Version Is not possible orelse rebuild the new centos server commission from the beginning.
* License cost

Shall we proceed the centos 7.9 in our production environment and advise me.

No. You would be misguided to deploy new CentOS 7 instances now. It goes EOL in less than 18 months so in 18 months you will be doing it all again. Pick one of the other RHEL rebuilds with a newer version number, 8 or 9, and use that instead. Don't use CentOS Stream as it is a permanent beta product. Use one of Rocky, Alma or OEL.

CERN/Fermilab chose Alma, but Rocky is just as good. (The devil is in the details.)

* Upgrade the latest release CentOS Version Is not possible orelse rebuild the new centos server commission from the beginning.

What does that mean?

* Support Level & SLA Escalation is there. Otherwise, we always we will depend into LINUX Forums or Open-Source Community Support.

You need a distribution that is supported by a paid support agreement. Red Hat Enterprise Linux, or others. Not CentOS, Rocky or others.

[TrevorH]

Yes, if you need support then your only options are RHEL or perhaps OEL.

[jlehtone]

There are companies that apparently sell support services even for users of (some) rebuild distros.
(TuxCare?)

(TuxCare?)

TuxCare is a good pick.
I've compared the packages that RH patched in their EUS 6 offering with TuxCare for EL6 and TuxCare patched alot more CVE's/packages than RHEL did.
For general usage I would definitely go with TuxCare and only in specific cases with RHEL EUS.
