CentOS 10 (centos 10) | Support by SupportedImages
Reliable Enterprise Linux Platform for Hosting Security and Network Management Applications.
I regularly perform :
Service monitoring
Log analysis
Package management
User administration
Storage monitoring
Network troubleshooting
Server health validation
The operating system is straightforward to manage and follows standard enterprise Linux administration practices.
I also like the predictable update process. During maintenance activities, updates can be applied without unexpected behavior, which is important in production environments.
Performance has been very good. Even when multiple application services are running, resource utilization remains efficient.
Another advantage is compatibility. Most Linux administration knowledge transfers directly to Rocky Linux, reducing the learning curve for administrators.
Most of my daily work is performed through SSH sessions and command line tools, which is not a problem for experienced administrators but may require additional learning for newer users.
However, this has not affected our production environment. Once administrators become familiar with the operating system, management becomes efficient and straightforward.
Rocky Linux has provided excellent stability, performance, and reliability for the applications we manage, Because of this experience, I would recommend it for organizations looking for a dependable enterprise Linux operating system.
My involvement is not only from the application side but also from the server administration side. During deployments, upgrades, troubleshooting activities, health checks, and maintenance windows, I work directly on Rocky Linux servers.
On a daily basis, I use Rocky Linux to verify service status, review logs, check disk utilization, monitor CPU and memory usage, perform package updates, and validate application services after maintenance activities.
Some of the commands I frequently used include :
systemctl status
systemctl restart
journalctl
top
free-m
df-h
ls
cd
cat
grep
tail-f
dnf update
Rocky Linux provides a stable operating system environment for our production applications. The operating system has helped us maintain reliable uptime and smooth application performance for platforms that are critical to our daily operations.
The biggest benefit for our team is stability. Once applications are deployed, the operating system runs consistently without requiring frequent intervention, allowing us to focus on application management rather than operating system issues.
Fast Response Times and Strong OS Stability
Rocky Linux: Stable, Reliable RHEL-Like Experience Without the Licensing
Performance has been solid so far, I’m running it on a couple of servers and also using it personally and it just stays out of the way. Updates are consistent and I haven’t run into anything major breaking after upgrades, which is always a concern with server environments.
Another thing I like is the cost side, not having to deal with licensing like RHEL but still getting a similar experience is a big plus. It also integrates well with the usual tools we already use, so there wasn’t much need to change our setup. Overall it just feels reliable, which is really what I want from an OS like this.
We are also using LXD for containers, and right now Rocky 10 images are not available there, only Rocky 9. Because of that, all our project containers are still running on Rocky 9, which isn’t ideal since we have already started using Rocky 10 in other places.
Other than that, there are occasional minor issues here and there, like certain packages or repos not being immediately available or needing a bit of manual setup. Nothing major, just small things that add up sometimes.
Since it’s RHEL compatible, we didn’t have to change much in terms of setup or tools. Most of our existing configs and workflows just worked, so the transition was smoother than expected. That saved a lot of time compared to switching to something completely different.
It also helps with consistency across environments. We’re using it both for servers and some personal setups, so it’s easier to manage and maintain everything in a similar way. Overall it just gives us a reliable base to run things without worrying too much about stability or unexpected issues.
Stable, Secure, Production-Ready Enterprise OS at No Cost
Open-Source Flexibility That’s Easy to Customize
A Free Open Source Linux That Rivals Red Hat
Cost-effective platform has enabled extensive test environments with rapid server expansion
What is our primary use case?
My main use case for CentOS is that in the past, I used it as a Linux workstation, and currently, I use it as a CentOS server where we require RHEL-based server functionality.
What is most valuable?
The best features CentOS offers in my experience are that it is reliable, cost-effective, and easy to scale.
When I mention reliability and cost-effectiveness, I explain that our product-based company uses a performance testing tool, so to generate load using the tool, we use CentOS generators, which are also known as VMs. We spin up a number of VMs in different locations such as Central, East, and West. If we purchase a subscription, it requires a good amount of money, but if we use CentOS, it is free of cost, and we can scale from more than 20 to 100 servers.
The biggest benefit of CentOS for my organization is cost saving.
CentOS has made a positive difference for my team and company by making scalability easier. For testing, sometimes we require 50 to 200 servers in different locations, and I can easily spin up and scale in and scale down.
What needs improvement?
CentOS can be improved, but I have not yet faced any kind of issue or hectic problem.
For how long have I used the solution?
I have been using CentOS for six plus years.
What do I think about the stability of the solution?
CentOS is stable in my experience.
What do I think about the scalability of the solution?
CentOS scalability for my needs is easy to scale.
How are customer service and support?
I have not used customer support for CentOS.
Which solution did I use previously and why did I switch?
I did previously use a different solution before CentOS. Before CentOS, I was not using any solution.
What was our ROI?
I have seen a return on investment in terms of money saved and fewer employees needed.
What's my experience with pricing, setup cost, and licensing?
Regarding pricing, setup cost, and licensing for CentOS, there is no cost for licensing or setup pricing, so it is easy to set up and scale up the server.
What other advice do I have?
CentOS is more similar to RHEL. My advice to others looking into using CentOS is that if they require RHEL-based or RHEL flavor OS, they should definitely go for CentOS because it is free; if they use RHEL, it requires a subscription. I would rate this product a 9 out of 10.
Which deployment model are you using for this solution?
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Great RHEL Compatibility Backed by a Large, Helpful Userbase
ROCKY LINUX PRINCIPALS
Migration to open source has reduced operating costs and supports reliable enterprise workloads
What is our primary use case?
My main use case for CentOS is that I use it as an enterprise server for running multiple software applications like Apache, JBoss, and other middleware software.
I can give you a specific example of how I use CentOS as an enterprise server: multiple software as a service applications are deployed on CentOS servers, running Apache HTTP servers for web traffic, JBoss application server for application servers running Java applications, and multiple other purposes.
CentOS is the closest and best distribution other than Red Hat Enterprise Linux, making it a solid choice if you do not have the budget to spare.
What is most valuable?
In my opinion, the best features CentOS offers are that it is an easy to use Linux distribution based off Red Hat Enterprise Linux, which is very solid and very well known across the industry, providing a good mix of features and reliability. CentOS is my go-to Linux distribution.
What I find most valuable about its reliability or feature set is that stability and reliability are key factors. Our staff is very knowledgeable in Linux, which is rare, and we do not rely on the community. I have access to Red Hat's knowledge base site, which is a great source of knowledge material, and it translates brilliantly to CentOS.
CentOS has positively impacted my organization in several ways: stability, reliability, and performance have improved our company cost-wise, especially moving out of paid operating systems for running distributed software. The cost is the main factor in this positive impact.
What needs improvement?
I do not find anything that can be improved in CentOS. I am a huge fan of it, and there is hardly anything that Linux in general does not already provide. I think CentOS is the best and closest thing to Red Hat Enterprise Linux, which I consider the golden standard for Enterprise Linux.
CentOS is perfect as it is.
For how long have I used the solution?
I have been using CentOS for more than ten years.
What do I think about the stability of the solution?
CentOS is absolutely stable.
What do I think about the scalability of the solution?
CentOS's scalability is great, and I do not have a problem with it.
How are customer service and support?
I do not know much about the customer support for CentOS, as we do not really need much support with our staff being very knowledgeable in Linux.
Which solution did I use previously and why did I switch?
I previously used a mix of Microsoft and Red Hat Enterprise Linux operating systems, but since then, I switched almost everything to CentOS.
How was the initial setup?
My experience with pricing and licensing for CentOS is that it was quite easy. The setup was not easy, but it is something that my team is very familiar with, making it easy for us. I understand that people who are not familiar with Linux may have a hard time with it.
What was our ROI?
I have seen a return on investment. My team had some time saved, but it was not significant. The money saved was significant, approximately fifteen percent of our IT budget.
Which other solutions did I evaluate?
Before choosing CentOS, I evaluated other options such as Red Hat Enterprise Linux and Ubuntu. I ended up choosing CentOS since that is where my staff is more knowledgeable, making it the operating system we would be more familiar with.
What other advice do I have?
Regarding cost savings, we have saved from a few hundred thousand dollars yearly to one or two million in the last years of transitioning, mostly because of moving out of other paid operating systems. I do not have any knowledge on how this budget was spent on other ends.
My advice to others looking into using CentOS is that if you are looking for a Red Hat Enterprise Linux alternative, CentOS might be the thing for you, especially regarding costs.
I love CentOS. I have a CentOS sticker on my laptop, and it is not just another tool for work; it is something that goes beyond that. Open source software is a belief that is very strong with me. I gave this review a rating of ten out of ten.
