Kali is quite honestly appropriate for use on a Test Lab, a Virtual Machine, it will even run on a Raspberry Pi. It is the most popular tool used in most all training courses. It can be uses in home labs, work labs and production environments to perform real life scans for vulnerabilities among other things. It is the most popular tool for Cybersecurity tool.
Large scalable environments. Currently working toward SAP setup. Things have been stable so far. Uptime is great, aside from normal patching reboots. The only thing I can think of where Rhel wouldn't be too great is a workstation. Works well for most things, but I've found a few tools that there isn't a Linux port for.
It has a really easy way to fix security issues, just "yum update" and you're ready
[ Red Hat Enterprise Linux] (RHEL) is widely supported by vendors, so there's no need to compile drivers, modules, or applications from source to have a ready-to-use solution
The way [ Red Hat Enterprise Linux] (RHEL) is supported help us to have a long server lifecycle (10 years), which simplify a lot our compliance-
While the command line installation runs well, the desktop GUI tends to be resource intensive at times
The GUI based install menu does not scale well at times resulting in some menu options spilling offscreen
By default a menu based network manager should be included, from my experience particularly with the minimal install, this was not the case resulting in me editing the configuration file directly. Additionally, network tools should also be installed by default.
RHEL has most of the features that are required by an ERP solution. If you need any additional packages, RHEL has a great repository and a very easy package installation/upgrade process.
Red Hat support has really come a long way in the last 10 years, The general support is great, and the specialized product support teams are extremely knowledgeable about their specific products. Response time is good and you never need to escalate.
The hard feature to be beat Kali with is the amount of preinstalled tools. I.e. Ubuntu is great but you would have to install each and every tool separately
We have tried other vendors but we don't have a strong support team, so Red Hat can help with this stuff. Also we use RHEL because it gives us security when setting up our services. We try to standardize our DC and work as much as possible with RHEL due to its ease of use, its support and the information that is found is very useful when running into a problem.
Till now Kali Linux have not made a single penny negative impact on our companies business , its so powerful and useful at the same time for our company.
Overall, RHEL has helped us achieve heights in performance management and handling a large crowd at once with its huge management capacities. It is highly reliable and if used with apt load balancers you will not require more than one backup server because the crash frequency is minimal.
No negative impacted has been faced as of now since using RHEL.
