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 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."
"There are a lot of sources on the internet that you can use to solve any issues, and people share their experiences. It's not a closed system"
"It’s scalable."
"If I need to install a feature or fix a server issue, I can easily find answers online. The CentOS community is also vast and helpful."
"The product is based on Red Hat and very stable."
"The most valuable feature is performance."
"We successfully installed MicroStrategy 10, Composer for PSP, Laravel, and many PSP libraries on CentOS."
"The solution is very stable, there are no bugs or glitches, it doesn’t crash or freeze, and it’s reliable."
"Flatcar's support is good, and the version I am using is stable and allows us to make needed changes."
 

Cons

"Often, the solution doesn't scale as you expect."
"CentOS, being Linux-based, is the best in security, but it needs more on the security side for CentOS RADIUS server."
"They could build more options into the wizard."
"Integration with Open Stack could be improved."
"The solution could be a bit more user-friendly. In terms of commands, it's all CLI and there isn't any GUI which can make it challenging to use for some people."
"I'd like to see better integration with Open Stack, because it can be a bit of a struggle."
"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 server system is a little bit tough to manage."
"The development teams could sharpen their skills. They should offer applications on the net."
 

Pricing and Cost Advice

"There is no price or licensing required — it's open-source."
"I'm not required to pay a licensing fee."
"This is an open-source solution, so there are no licensing costs involved."
"The solution is not subscription-based, unlike Red Hat."
"CentOS is an open source that is free of cost."
"This is a free solution."
"It's free."
"CentOS is an expensive solution. There are other solutions that are rated at the top that are not expensive, such as Red Hat."
