Good for Enterprise testing but license is expensive can use CentOS for some of the test machines
A review from a day to day user of Redhat
What do you like best about the product?
Awesome stability, used for hardware dev. Very innovative and long lasting OS that came with multiple intuitive features.
What do you dislike about the product?
Lack of support and update compared to Ubuntu or other offerings.
What problems is the product solving and how is that benefiting you?
Hardware Dev. REHL was easy to use and came with lots of linux features that made it simpler to navigate.
I have been an Enterprise Architect and Program Director for five years...
What do you like best about the product?
It is robust and yet fairly easy to design a standard configuration for our servers.
What do you dislike about the product?
Sometimes, our standard configurations might be a bit of 'overkill' for some applications, but as I said before, it is a robust, reliable operating system.
What problems is the product solving and how is that benefiting you?
At my current location, we have hundreds of Red Hat servers and are moving them into the Cloud to take advantage of installation and maintenance opportunities the cloud affords.
Recommendations to others considering the product:
I recommend getting Red Hat. WHile there might be a slight 'learning curve', the benefits far outweigh the negatives.
Solid education and coding OS
What do you like best about the product?
Fast, reliable Linux distro. Great coding environment. Solid pre-installed application base.
What do you dislike about the product?
The UI is a bit garish and dated. Some default apps are not ideal.
What problems is the product solving and how is that benefiting you?
Used primarily for compiling code in educational environment. CAEN systems run this!
KVM the FLOSS virtualisation solution
What do you like best about the product?
Kvm is supporting Intel's VMX hardware virtualization which is optimal on intel powered system, I assume it's the same with other ventors isnt AMD providing vt instuctions set too ?
What do you dislike about the product?
It can be confusing to have several incompatible virtualisations system on the same host , which is not possible but afaik there is no abstraction service to switch from one system to an other.
Setting up network interfaces can be confusion, and supporting accelerated GPU is not fully supported, so it can be inappropriate to test opengl application, that said vmware with mesa gallium driver can be an alternative to consider.

What problems is the product solving and how is that benefiting you?
I used kvm to test some distros like Tizen:Common which are using the same architectures.
Recommendations to others considering the product:
you can also look for libvirt and virtman which is providing a nice user interface if you're not confortable with command lines or man pages. Something also useful is to disable the GUI windows and use ncurses mode to use the guest machine on host's terminal. Last but not least even if kvm is a good product maybe there are other way to address isolations needs, for instance containers can also be considered, check also for CGroups, LXC, docker, rocket ...
Best solution for automating application and ETL batch jobs
What do you like best about the product?
All functionality and features available. Easy to install, upgrade and maintain open source applications.
What do you dislike about the product?
upgrading the OS between major versions.
What problems is the product solving and how is that benefiting you?
all our ETL and application programming is run on this server.
Recommendations to others considering the product:
easy to implement all solutions and schedule batch jobs using shell scripts.
