What is our primary use case?
My main use case for
Red Hat Enterprise Linux (RHEL) at this point is lab machines for students in the engineering department.
I use RHEL on-premise for the most part; we have some of the server infrastructure that I work on now in ROSA, OpenShift.
I am starting to work my AI workloads with RHEL.
What is most valuable?
Red Hat
Enterprise Linux (RHEL) helps me solve pain points such as getting students the access they need and supporting all the software they need to use.
The most valuable feature of RHEL that I have found is the dependency resolving; it is nice not having to worry about the programs interacting with each other for the most part, except for when it has the locking problem, but they improved significantly with that.
The feature in RHEL that I use to navigate my security risks is SELinux, which is the big security mechanism we use to make sure that the contexts are right between the different parts. I am mostly removed from that, and then I use yum for the most part or sometimes I end up using Ansible to do the patching.
Red Hat Satellite helps me manage and maintain my cloud environment by locking the packages to known good states, so that we have infrastructure that we know runs.
The features that I think will help my AI workloads in RHEL include using natural language to determine what to get the system to do to get up to date. I just did a lab the other day, and it was impressive.
RHEL plays a role in my company's implementation of the zero-trust model mostly in the systems themselves; the other aspects are usually pushed out into other departments and groups.
My company's process for managing regulatory compliance has shifted most of that responsibility over to the security teams, and RHEL plays a role in our compliance and auditing workflows.
RHEL has helped to mitigate downtime and lower risk; it is nice coming from Linux from Scratch implementations and having the software and package infrastructure we discussed before, allowing the ability to update and do the dependency resolution so they do not conflict with each other.
What needs improvement?
Red Hat
Enterprise Linux (RHEL) is doing a good job by drawing back on the dependencies to keep things running smooth, and that is the biggest strength.
I would improve RHEL as a platform by noting that you have significant advantages over the competition that I see; I think being more proactive with emerging issues is important, especially with all the new vulnerabilities that we have been dealing with the past couple of months.
I think they should ensure more security, but if I step back and look, you cannot do anything before you know about it, and there has been a lot of difficulty with all the regulatory requirements that go into that.
For how long have I used the solution?
I have been using Red Hat Enterprise Linux (RHEL) for at least 15 years.
What do I think about the stability of the solution?
I do major version upgrades using RHEL and
Ansible Automation Platform all the time.
My experience with major version upgrades using RHEL and Ansible Automation Platform is that it works well, although sometimes there is a need to get the right software set up in Satellite in the backend at the versions when it is changing for the Red Hat-specific upgrade paths.
From time to time, I experience some downtime, but it is not usually the OS; it is usually the user or the underlying hardware.
What do I think about the scalability of the solution?
Regarding scalability, I tried to expand its usage, and we handled scaling up with the hardware and scaling out by multiplying the resources.
How are customer service and support?
I would rate the customer service and technical support a seven because sometimes it takes a bit to reach someone at your level.
Which solution did I use previously and why did I switch?
Prior to adopting RHEL to address those needs, I was using Linux from Scratch.
I switched to RHEL because we merged with a different part of the university and RHEL came with it.
How was the initial setup?
I would describe the experience of deploying RHEL as it works well for the most part; the kickstarts were quite nice coming from building from source.
What was our ROI?
From my point of view, the biggest return on investment when using RHEL is that it works and is supported by all the niche software that they need at the university.
What's my experience with pricing, setup cost, and licensing?
My experience with the pricing, setup cost, and licensing of RHEL is that from my end I am removed from where I am at, but I know that the site license allows us to use the product.
Which other solutions did I evaluate?
I have evaluated other solutions instead of RHEL.
I looked into Ubuntu, and the reason I always picked RHEL is that the software is supported on RHEL, which is the determining factor.
What other advice do I have?
I want to look into Red Hat Enterprise Linux (RHEL) Image Builder or system roles for sure.
I have used Red Hat Satellite or Lightspeed.
Overall, I think Ansible Automation Platform is good; it became too expensive at the scale we are at for how we are utilizing it, but it is an awesome product.
I assess the knowledge base of RHEL as pretty good, and I use it when I need it, although I tend to encounter those unusual edge cases a lot.
My overall review rating for Red Hat Enterprise Linux (RHEL) is eight.
Which deployment model are you using for this solution?
Hybrid Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
