I think all Linux distributions should look to RHEL distributions to learn one advanced management lesson. That is eternal immortality.
What does that mean, specifically? It means that Ubuntu, debian will kill itself, or can be described as suicidal, when faced with a severe test of load pressure.
RHEL, on the other hand, has a very smart strategy. It always keeps the tty accessible to the Linux console. It always keeps the system able to respond to control commands.
It can rather perform tasks very slowly, even when the load is as high as 90,85, and it can still respond without killing itself.
This is crucial when running Linux in an enterprise environment. Because if you use debian/ubuntu, your business machines, one by one, will commit suicide, the server kneel, is hundreds of servers one after another.
RHEL Linux, on the other hand, is unyielding and never dies. You can log in to each machine, operate it, and kill any business that is taking up too much resources.
Keep the system running smoothly.
This is the strongest gesture of Linux.
So if there's one thing I love about RHEL, it's that it's immortal;.
If there's anything wrong with debian/Ubuntu, it's that it kills itself.
