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

"We used the solution as an operating system."
"It is better than Ubuntu Linux."
"The user access level is most valuable. When you do administration with CentOS, the number of customizations that you can do for each user is higher than other solutions. It is very customizable."
"The most valuable feature is performance."
"The open architecture is useful for us. That's why we're using CentOS."
"We particularly like that we can remove the graphic user interface to minimize attack settings for the operating system."
"Setting up CentOS is straightforward, and you simply boot from a CD to get started."
"There's lots of great documentation available."

Cons

"I have had a tough time with the product's scalability, making it an area where improvements are required."
"The price of CentOS could improve."

"Currently, CentOS is not providing support, so you will not get new packages that are compatible with that operating system."
"Continuous deployment is the only thing that can be improved."
"The development teams could sharpen their skills. They should offer applications on the net."
 

Pricing and Cost Advice

"Once you buy the license, Linux will provide you with yearly or monthly patches, so your systems will be scalable for a long time."
"It's free."
"CentOS is cheaper compared to Windows."
"There is no price or licensing required — it's open-source."
