Here you can discuss every aspect of Debian. Note: not for support requests!

Why Redhat is in demand/preferred over Debian
It isn't , here we don't use Redhat , nor want it , We prefer Debian and that is what we use.

Objectively, I think Debian is much better than Red Hat and derivatives. Here are my reasons:

1. apt is a much better package management tool than yum. For example, we can backup the entire system by just archiving /var/cache/apt/* and restore when required. Yum can't support this as it has delta rpms which are just parts of a whole package. apt-get install * is also much faster than yum install *.

2. Debian is minimal and simple. With Debian, all I have to do is add a bunch of iptables rules like the one shown below and my firewall is secure. With RHEL/Fedora, its a whole new firewalld daemon that I have to learn.

Code: Select all

iptables -A OUTPUT   -p tcp --dport 80 -j ACCEPT #http
#Set default policy to deny all traffic
iptables -P INPUT DROP
iptables -P OUTPUT DROP
iptables -P FORWARD DROP
3. Debian supports multiple architectures (almost everything under the sun, except perhaps smart-phones). Unlike RHEL that runs on a chosen few machines that are profitable for Red Hat, Debian universally supports all PC architectures. The only reason mobile isn't accessible yet is that Smart Phone vendors aren't opening up their specs and firmware code to Debian.

4. Debian has compatibility with most hardware and software and runs out of the box without issues. I cannot say that for RHEL or Fedora.

Lets see when it would be available for Smartphones as well, then howcome Ubuntu & Kali are there for Mobiles though they are based on Debian.

I currently do geek work for a rather large gas and electric utility in the midwestern US and all the Linux instances here are SuSE.

If your business can lose thousands or millions of bucks an hour during an outage you're going to make real sure you have third-level support available. I spent a couple of years as an IT critical incident manager and you'd better believe that if there's *any* hesitation from support teams when resolving an issue we require the support team to engage the vendor.

The business requirement drives the support model. I'm a big supporter of community-based problem resolution, but my shareholders wouldn't be nearly as understanding if stuff's broke and their revenue stream is impacted :)
IMO wizard10000's explanation is one of the best in this topic, however, (as I also have experience in this matter) my point of view is a bit different.

It's true that for small to medium businesses it's simply cheaper to buy 3rd party support than hiring full-time highly specialised and professional staff.

However, for businesses which are operating bilions of $$$, 3rd party support is completely useless and in some special cases even harmful.

1. A company which is selling support services doesn't take any responsibility for effectiveness of their support - no guarantees of any kind - so if crap happens, it just happens.
But what's funny, in addition to paying fees for the breakage, You also pay for the useless services. It's far more reliable to buy a financial insurance - at least some part of financial losses can be compensated this way, and this a real help for Your business.
In case of huge businesses it's absolutely better solution to hire best-in-class specialists - they have better chances to prevent and fix the problem, because they perfectly know their systems.
A guy from external company, who only occasionally connects to the system, usually doesn't even know how Your server room looks like, what machines are there and how they are connected/configured - because this was done by someone else...

2. 3rd party services can be harmful in case of military and government systems - real life example: Edward Snowden :)
In other words, a 3rd party company, which hires hundreds if not thousands of people is unable to guarantee full security of information.
This is most obvious in case of military systems, but business data/informations can be also critical and valuable.
