RHEL is still an industry standard, but there are other compelling options to consider.
What do you like best about the product?
Red Hat offers great support and their education and certificate options are second to none. The company has a rich history and thus far it appears as though IBM is going to allow them to continue without meddling. It appears that their entry into containerization is well thought out. I also liked the length of time they support their releases -- this is important if you don't need to kep on the bleeding edge of distributions and value stability over feature set. In this way you don't sacrifice security.
What do you dislike about the product?
We found that we were having to compile too much software that we could get pre-packaged using a debian/Ubuntu distribution. Support, while very good, did cost more than from Canonical. Automated patching was not easy or straightforward for us without significant work and customization. There are some specialized packages, especially dealing with image and pdf conversions, which are much easier to install and keep up to date on debain based operating systems. We found that this ease of updating was more important to us in many cases than the other benefits Red Hat provides.
What problems is the product solving and how is that benefiting you?
We have platforms which require a unix-like operating system to run. Red Hat provided that for us. We have not yet made the pivot to containerized workloads, however. Uptimes for our Red hat servers were much better on the whole than for those servers we ran on Windows. Where possible we opted to go with Linux based operating systems rather than Windows, for both cost and stability reasons.
Recommendations to others considering the product:
Consider looking at containerization if it fits your use case. Look at specific packages you require and determine their availability on multiple platforms if you are not able to containerize. Support costs should be considered as well, of course.
Rhel
What do you like best about the product?
Best support in the business. Wonderful operators
What do you dislike about the product?
Tough indecisiveness when working to deploy changes
What problems is the product solving and how is that benefiting you?
All systems go with virtualization and cloud based security
KVM is flexible, available at no cost, but not necessarily for the faint of heart...
What do you like best about the product?
I like that there's no licensing cost. I like the flexibility on tap. Overall with some technical familiarity you can deploy in [relative] confidence.
What do you dislike about the product?
I dislike the steep learning curve, the lack of commercial support, and the finicky nature of the older, less mature versions. Centralized management is not really fleshed out, even though things like WebVirtMgr can be configured. Maintenance can be tricky. Migration from one host to another isn't very straightforward either.
What problems is the product solving and how is that benefiting you?
In areas where there's no virtualization budget but you need VMs, and can't or won't use VirtualBox or Xen, KVM is an option...
Recommendations to others considering the product:
I just read that Amazon is moving AWS away from Xen and towards KVM. That's huge news. I would imagine that it will only become better, more stable, and more fully featured with that kind of user base behind it, on top of the current base!
Great but lags
What do you like best about the product?
How fast it connects, plug in and it will pop out immediately!
What do you dislike about the product?
How it lags, some color pixels will turn and slows down the program
What problems is the product solving and how is that benefiting you?
Connecting with servers such like HP and ZT models. No benefits!
Great solution for group computation
What do you like best about the product?
It has an easy to operate interface, and it can be installed on many machines.
What do you dislike about the product?
Not everyone has intuition for linux and this tends to lead to a high learning curve.
What problems is the product solving and how is that benefiting you?
It solves the need for united computation. It has realized such. This is to run particular software that is specifically run off the command line.
Recommendations to others considering the product:
It is a safe and reliable operating system and it runs smoothly on many machines. The only downside is the learning curve.
