Red Hat Enterprise Linux (RHEL)

I guess to give it more context, my first job in the Linux ecosystem was in web hosting. And that was basically a Cintas shop and it was all run extremely lean and very bootstrappy do it on your own. You don't get any support. And for that environment, it was kind of just the way it is. It's very cutthroat. You have to move super fast. Once I moved over to the corporate side, every company I've worked with has been on rail. And the thing that really kind of makes it the best choice compared to using another operating system, another flavor of Linux and just kind of figuring out your own is the amount of support that Red Hat gives rail as far as extra tools like Satellite Insights and what's coming up now with Ansible and especially Ansible. Lightspeed, but also SLAs and stuff like that. Because yeah, I mean it was good learning in that first environment because there were no tickets, there was no support. It was figured out. But nowadays it's just nice to have an SLA agreement. I can just open a ticket. I say that that's something that does really well, but I also want to see it expanded, just more like vendor support at an enterprise level. I'm not sure yet what that would mean. I just have that every time we come up for renewal, I look at the price tag and it's like, what else can we do here? I like what Red Hat is doing just more.

Where it's very well suited is just if you're rolling out systems quickly, web front ends, and so forth. I think it's really well suited for that. Even backend operations. It does a good job. However, I do think that it's not as industrial-proven as other operating systems out there. Like say the banking industry, they love AIX, cause it's IBM, it's been around forever and it's rock solid. And to try to get that much computing power in an intel box is difficult. So RHEL is limited in what it can do versus some of the P series and I series stuff that IBM does.

Like I said before, with the automation environment RHEL is well suited to run the Ansible Navigator and the Ansible execution environment builder. So we can create our execution environment on RHEL natively instead of having to figure out how we do it as Ubuntu or other platforms.

It's well suited for installing pretty much anywhere and it's usually the documentation is very good and there's a lot of support from the documentation and training to make good use of the product. It's not as good as a workstation, it's better as a server product. It's not necessarily good in kind of other situations as well because of some of the licensing constraints.

I mentioned it provides a consistent base for our developers, for our applications. In an institution or enterprise where you want security, you want a specific type of setup to your system. Red Hat excels at that. It's not really geared toward that side of things, but we have users, I'm a power user who likes to use Linux on my daily commuter laptop and I prefer to use a Fedora or a Debian than a Red Hat just for the difficulty of configuring a specific use case like an end user would be.

Critical production environments are the best for RHEL case as the product ensures the security, stability and it is backed by the world class support that the most of the companies (and their shareholders) would appreciate.
It might not be too suitable for the startups or even some Dev teams within large enterprises, depending on their internal culture and practices. Though things definitely improved over the last few years and there is no strong case for the teams not to use RHEL nowadays.

In my opinion RHEL is extremely capable for most all work done. Maybe not as easy for some office type applications but still very capable.

Development environment for developing microservices based solutions. The orchestration to carry new applications from development to production deployment.

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.

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. I'm happy using RHEL.

I have had a very easy time imaging RHEL machines and getting them to the state i desire. I find pam very confusing and how to make changes that are required in the classified environments. it would be nice if there were an easier way to see required dependencies to prevent me walking back and forth multiple times to complete one install.

Installing and configuring RHEL has been an ease to learn and execute. Most of the applications that I run requires linux or unix, which RHEL is my companies choice because of it reputation and the resources it provides.

For large and small scale applications which limited CPU usages works level but Red Hat need to develop think for DB based systems to make sure they run without any performance degrade

we are using Red Hat among 8K servers and patching is very fun for us :)

RHEL provides the tuning needed for our needs. We are able to use the repositories provided to satisfy most if not all of our customers' needs. We are able to provide solutions to our end users who didn't know they were even available.

All our Linux solution is based upon RHEL since a simple webserver to a structured Cluster solution, including OracleRAC, VCS. We're starting to use container - Docker and OpenShift as well. TACACS+ solution for router/switches authentication works perfectly. Now for improvement the OracleRAC under RHEL works fine but I don't know if this is a Oracle strategy to sell their own Linux distribution but, some oraclerac modules fails sometimes running in RHEL.

This is highly recommended to support servers to transactional applications.

RHEL is excellent for the usage of Operating systems where a high available Linux is needed and the following features are needed: - High available Linux and configurations in the cluster - Patching cycles for vulnerabilities is needed on an ongoing basis and also configuration management with Red Hat Satellite - Support within 7x24. - Integration using automation of a high amount of servers needs to be accomplished. For example, using Ansible

RHEL's stability is a good fit to host mission-critical applications/databases. Storage is easy to scale up and easy to work with Oracle ASM.

If you're running Linux in the enterprise, Red Hat should be your first choice. It's well-supported and third-party products for Linux will be designed to work with Red Hat. They may behave differently and less stably under other Linux operating systems—McAfee, I'm looking at you here! If the question is "Will x work with this flavor of Linux?", with Red Hat, the answer is always a Yes.

All servers work great. It is reliable, fast and secure. But it's not as intuitive as it could be for desktop use, a better GUI would help this. So far, we have not found an application that this will not work for.

RHEL is a rock-solid server for some essential network services, such as NFS, DNS, SMTP, Apache, Tomcat, etc., in addition to running third-party applications. It may not as well suited for things like DHCP because of the lack of active directory integration. Also, if users are used to NTFS permissions backed by a domain, then running as a file share may not be as beneficial as running a Windows CIFS server.

It's suited for data center and voice that needs to be very secure and robust. If basic user level changes are required, then Linux fails since it's not very user-friendly for the layman.

RHEL is well suited for deploying servers and applications. If you're happy working on a terminal and do not want much of graphical user interface, then RHEL is your cup of tea. It is highly reliable and makes you super happy performance-wise. You can easily set it up running and start deploying your servers and application on this OS and not worrying much about security since the OS itself is very secure.

If you're not fond of working on a black screen and need some sort of animations and cool icons to move around, then I would suggest RHEL is not your cup of tea since it lacks a lot in those aspects. However, the unbeatable performance of the OS is a major advantage which everyone shall consider while using computers.

RHEL is very well suited for enterprise solutions. It works great both on physical and virtual infrastructure. It definitely requires users to have a good level of shell programming knowledge, especially if you are going to administer the OS.
