Debian is very well suited for application servers, web servers, file servers, hypervisors (personally, we use Proxmox for some hypervisors and this is based on Debian), and much more. It can run on various CPU architectures and scales well from large to small. We have Debian DNS servers running on Raspberry Pis, and large application and database servers running on powerful Debian installs in our racks.
If you want an OS that is rock solid, easy to manage, and predictable, Debian might be the OS you're looking for. The official packages are generally far from being bleeding edge versions, but this means that you are using packages that are battle tested and will not break compatibility at any point during its life-cycle. This, to me, is one of Debian's core strengths and a good reason for recommending it to others.
On the flip-side, the lack of up-to-date versions of various packages may be an annoyance if you actually do need to be using the latest version of such a package. If you need to be using more modern versions, you will need to remedy that yourself or look at an alternative distribution. Ubuntu may be worth a look, in this case, being that it is basically Debian with newer packages and some minor differences here and there.
Personally, I would not recommend Debian for a graphical desktop OS. You'll nearly always be better off with one of the Ubuntu flavors for a modern desktop with all the bells and whistles you'd expect with a GUI desktop.
Red Hat Enterprise Linux (RHEL) is well suited for cloud environments, fast deployments and to run non-intensive apps/tools (with low memory and low cpu consumption).Red Hat Enterprise Linux (RHEL) might not be suited for really huge databases and intensive CPU processing.
Virtualization, like the operating system level task. I see this product is very good and it blends very well with the middleware components like all the JBoss and other things. And other than that, either you install it or a virtual machine or physical servers, it works seamlessly anywhere. And if you want to go further, like Red Hat OpenShift or those things also work very nice with it.
Well, one of the things, this ties right back to my previous answer from what it sounds like, the cloud platform for Insights doesn't currently have an easy way to generate CVE compliance reports, or do scans for where you have remediations required, but it does not currently produce those reports in a way that I could just hand off to our security team and be like, here's our compliance, here's where all the things are specifically because Red Hat does backporting of patches and a lot of security tools don't know how to handle that and think that we're vulnerable when we're not. So from everything I've heard, it's possible. That's why I'm excited for it. But it's not easily pushed button generated report yet. So we're working with them to get that in there.
Debian is one of the most well-thought-out, logical, and intuitive Linux operating systems you can use. Configuration, package management, file system layouts, etc, are all based on many years of usage, and it's very rare to find anything surprising or confusing in everyday usage. Package management and updates are handled by APT in such a way that once configured, you can almost guarantee your system will behave as expected for the lifetime of its service. Top-notch system integration provides all the tools you'd expect from a modern Linux system, with all the stability you demand from a demanding server OS.
The Red Hat Enterprise Linux (RHEL) distro is the simplest enterprise version of Red Hat that is enterprise supported and when you deploy as many VMs as we do, it is vital to have that enterprise support. On top of the enterprise support, having access to a commercially supported backbone for updates and upgrades is a huge plus.
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.
It's superior. I mean they're all Linux so it's all that code, but I find that the intangibles that you get with Red Hat, meaning the enterprise support, the lifecycle, that's what clearly makes it better than the rest of them.
