Solution Architect, DevOps Engineer at sonne technology
Provides open architecture but support has ended
Pros and Cons
- "The open architecture is useful for us. That's why we're using CentOS."
- "The main issue is the End of Support. For that reason, we will switch to another operating system."
What is our primary use case?
CentOS is an operating system, and our applications are running on EC2 instances.
I am using the latest version, which is version 6.9.
It's a Linux operating system, but it's compatible with cloud solutions.
This solution is used by over 1,000 clients. We don't plan on increasing usage because Red Hat announced that support has ended for CentOS.
What is most valuable?
The open architecture is useful for us. That's why we're using CentOS.
What needs improvement?
The main issue is the End of Support. For that reason, we will switch to another operating system.
For how long have I used the solution?
I have used CentOS for over eight years.
What do I think about the stability of the solution?
The solution is stable.
What do I think about the scalability of the solution?
It's scalable.
How was the initial setup?
Installation is straightforward. Deployment takes 10 minutes with EC2. In AWS, there is nothing to install because it's ready.
What other advice do I have?
I would rate this solution as five out of ten.
Because there's an EOS, no one is willing to use CentOS anymore.
Disclosure: My company does not have a business relationship with this vendor other than being a customer.

An easy-to-integrate solution, scalable and stable
Pros and Cons
- "It helps us install and deploy our applications."
- "More security features could be included in the next release."

Our primary use case for the solution is utilizing it as an OS in a virtualized environment. It helps us install and deploy our applications and other services accessed by other users, internally and externally. The solution is deployed on-premises.
What is most valuable?
We have found the ease of integration valuable. The solution is easy to integrate with other applications and with other services. For example, if you want to deploy something, it simplifies the integration with other applications and services.
What needs improvement?
The solution could include more integration of third-party solutions to check on the quality and vulnerabilities of the code.
For how long have I used the solution?
We have been using the solution for approximately two years.
What do I think about the stability of the solution?
The solution is stable.
What do I think about the scalability of the solution?
The solution is scalable. Approximately 1000 users are utilizing the solution.
How was the initial setup?
The initial setup was straightforward, and deployment took two to four hours.

What's my experience with pricing, setup cost, and licensing?

System Administrator at Confidential
The solution is extremely stable, can be installed in under ten minutes, and is free
Pros and Cons
- "The solution is extremely stable."
- "This solution is no longer supported and will not receive any updates going forward."
What is our primary use case?
The primary use case for the solution is to host web servers, application servers, or databases.
What is most valuable?
The most valuable feature of the solution is the stability and performance of the server.
What needs improvement?
The solution is an open-source version of Red Hat without some of the features. The solution can be improved by including some of the Red Hat features for free.
For how long have I used the solution?
I have been using the solution for over ten years.
What do I think about the stability of the solution?
The solution is extremely stable.
What do I think about the scalability of the solution?
The solution can be scalable depending on what you are using the server for. If you use the solution as a visualization system, it is scalable, but difficult to scale without having to use additional tools. Linux-based solutions require a lot of manual work unless other tools are used to automate.
How are customer service and support?
The solution is open source and does not have any official support only other users on forums.
How was the initial setup?
The setup is straightforward for advanced users and administrators. If you are a beginner the setup can be quite difficult, especially with the partitioning phase. The basic installation on the premises only takes ten minutes. If you are installing on the cloud there are a few extra steps that can take up to 20 minutes such as the provider's security, networking, public IP addresses, and some rules that have to be configured before the system is ready.
What about the implementation team?
The implementation was completed in-house.
What's my experience with pricing, setup cost, and licensing?
The solution is open-source and does not have any costs or licensing fees.
What other advice do I have?
I give the solution a nine out of ten.
This solution is no longer supported and will not receive any updates going forward. Oracle Linux is similar to the solution and is also Red Hat compatible. I recommend that anyone thinking about using this solution switch to Oracle Linux.
For anyone interested in trying the solution there is a lot of information and support that is freely available online.
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?
Microsoft Azure

Head of Department of operational and compliance at ACE GABON
Provides efficient virtualization and good security
Pros and Cons

We use this solution for web applications. We are customers of CentOS and I'm head of the operations and compliance department.
What is most valuable?
The product is very efficient when it comes to virtualization and good from a security perspective.
What needs improvement?
I'd like to see better integration with Open Stack, because it can be a bit of a struggle. The solution requires a lot of experience on Linux. I'd like to see the GUI become more user-friendly so that someone who doesn't have much experience can use it.

I've been using this solution for 20 years.
What do I think about the stability of the solution?
The solution is stable.
What do I think about the scalability of the solution?

What's my experience with pricing, setup cost, and licensing?
We're using the open-source version of CentOS.
Which other solutions did I evaluate?
I sometimes use Ubuntu for network service. The main difference is that if you don't upgrade with Ubuntu, you have to change the source and that can create problems that we don't experience with CentOS.
What other advice do I have?
If you have experience with this solution, it's a good product. Without sufficient knowledge of Linux it's important to purchase support with the product.
I rate this product 10 out of 10.
