Provides stability in testing with predictable updates but lacks long-term support for production use
What is our primary use case?
We started using CentOS for our operations as soon as it became available. Initially, we used CentOS for its long-term support. It served as a stable production environment. However, they changed from a long-term support cycle and started dropping new versions every two or three years, making it less ideal for stable production environments. We experienced some incidents after updates, which led us to switch to long-term support on AlmaLinux.
What is most valuable?
CentOS was a stable and predictable environment, providing a consistent update cycle once a month. Their updates initially followed the schedule of Fedora and RHEL distributions, focusing on delivering a stable testing environment. However, the update cycle changed when CentOS was prioritized for updates, causing stability issues. We began to experience incidents with updates that disrupted features. Consequently, our organization transitioned to AlmaLinux for its long-term support.
What needs improvement?
CentOS removed long-term support, and version releases every two to three years are not ideal for production environments because they necessitate frequent updates.
For how long have I used the solution?
I have been using this solution for probably more than ten to twelve years.
What was my experience with deployment of the solution?
We did not experience any problems integrating CentOS within our existing infrastructure because it remains a RHEL-based distribution.
What do I think about the stability of the solution?
I believe CentOS is stable, but we are gradually moving away from it. Currently, we have five to ten servers on CentOS out of our 60 to 70-service environment.
What do I think about the scalability of the solution?
I think CentOS remains a stable solution, but it is not our primary platform due to the reduced long-term support.
How are customer service and support?
We never used customer support as we did not pay for those services. However, I would rate the documentation about eight in terms of usefulness.
How would you rate customer service and support?
Positive
How was the initial setup?
Setting up CentOS is straightforward, and you simply boot from a CD to get started.
What's my experience with pricing, setup cost, and licensing?
CentOS is a free product with free updates. There are third-party companies available for support, but they charge varying amounts for their services.
Which other solutions did I evaluate?
We evaluated RHEL. It offers various enhancements, like the Ansible Tower, which includes a GUI and scheduling features. However, RHEL's pricing is high, making it less attractive.
What other advice do I have?
Overall, I would not recommend CentOS for production environments because it requires frequent updates every two to three years due to its lack of long-term support. However, for learning Linux or experimental use, CentOS is a suitable and cost-effective platform with ample documentation. I would probably rate it about seven to eight.
Which deployment model are you using for this solution?
On-premises
All the commands are user-friendly, and it provides good stability and security
What is our primary use case?
Many of my customers use Linux as their client operating system because it is more secure. Since it doesn't have a UI and there are a lot of anomalies and viruses affecting the UI-related applications, some customers prefer to have an operating system without a UI. I have seen most people use CentOS, Red Hat, or Ubuntu as a client operating system or server.
What is most valuable?
CentOS is very easy to use, and all the commands are user-friendly. Installing any package or application is pretty easy with CentOS. Security-wise, most of the latest security software and applications are compatible with CentOS. Updating the patches for CentOS is very easy.
CentOS is a stable, consistent, and secure solution.
What needs improvement?
The solution’s stability could be improved.
For how long have I used the solution?
I have been using CentOS for three years.
What do I think about the stability of the solution?
CentOS is a very stable solution.
I rate the solution an eight out of ten for stability.
What do I think about the scalability of the solution?
The solution is very scalable. CentOS is very good for any microservices or any application that has an auto scalability mechanism available. The number of users usually depends on how many users can access the OS through the network based on the bandwidth.
How are customer service and support?
The solution provides good technical support for all flavors of Linux.
How was the initial setup?
The solution’s initial setup is very straightforward.
What about the implementation team?
The solution’s deployment takes hardly 10 to 15 minutes. You can use the image to manually deploy the solution, or you can use the DevOps or any automation methods to deploy it.
What other advice do I have?
CentOS provides very good cost efficiency. It is a very efficient operating system without any hassle or inconsistencies. I don't see much difference between CentOS and Ubuntu. Ubuntu has a few more user-friendly commands than CentOS. Once you are familiar with the flavors, CentOS is also very user-friendly. For a new user of Linux, Ubuntu is a little bit easier.
Overall, I rate the solution an eight out of ten.
