Has supported reliable deployments and simplified issue resolution in complex environments
The most suitable feature of CentOS is its exceptional stability, security, and long-term support, which make it a popular choice for enterprise and server environments. CentOS is widely recognized for providing a stable and secure platform, especially suited for server and mission-critical workloads. Whenever we face critical work, it is easy for our team to handle. For long-term support, each CentOS release generally guarantees long-term updates, ensuring reliability for extended periods. For package management, we use YUM and DNF in the new version for flexible and efficient software management. It depends on our users' requirements for installing CentOS. Licensing for CentOS is above my management details, so I am not aware of this information. CentOS always provides good feedback, is easy to handle, and easy to troubleshoot. The experience with CentOS OS has been very good over the last two months. I rate CentOS nine out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The scalability of CentOS is good, and we can deploy the operating system on many types of hardware, laptops, and servers."
"We used the solution as an operating system."
"Asus technical support is very efficient."
"The product is based on Red Hat and very stable."
"I'm satisfied with the product; it fulfills our desired needs, we haven't had any issues with performance, the stability is good, the initial setup is easy, you can work with the UI or in command line if you prefer, and it is scalable."
"Our team loves working with the solution because it is very stable."
"The ROI is incalculable. We could not do our business without CentOS/Red Hat."
"It’s scalable."
"Flatcar's support is good, and the version I am using is stable and allows us to make needed changes."
 

Cons

"CentOS removed long-term support, and version releases every two to three years are not ideal for production environments because they necessitate frequent updates."
"Like every operating system, it could be more secure."
"There is no notification before updates are applied to the solution, which occasionally means that new functionality isn't compatible with how the product is currently being used, and causes issues."
"The performance could stand improvement."
"There could be more integration features included in the product."
"Previous versions were unstable."
"The price could be better. They could add more drivers in terms of peripherals and other things. Add more drivers for the Linux specifications in the next release. Right now, they are just pushing to have more drivers for Windows instead of Linux."
"CentOS should extend the support of the solution. The solution is set to have no update support in 2023."
"The development teams could sharpen their skills. They should offer applications on the net."
 

Pricing and Cost Advice

"There is no license required for this solution."
"CentOS is an expensive solution. There are other solutions that are rated at the top that are not expensive, such as Red Hat."
"There are no costs for CentOS, it is open-source."
"The price could be better. The cost depends on how the organization or a specific person licenses it. If you want the free version, there's Ubuntu which is supported by forums. You can pay for the license yearly or pay for a specific version."
"We are using a subscription-based license option for CentOS."
"There are no licensing fees for CentOS."
"CentOS is an open source that is free of cost."
"CentOS is a free solution."
