IT infrastructure executive at a computer software company with 201-500 employees
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.

Containerization on free Linux has reduced costs and has simplified application testing workflows
I think more stability could be improved, and there could be much more community support. There is good community support for CentOS mainly, but I think there could be a dedicated community for Docker for those people who are using Docker on CentOS. It could be very helpful. Sometimes, legacy systems do not work because those images are not available. If there were community support specifically for Docker on CentOS, we could ask other people if they have those images or libraries available, which would help us or others trying to run or test their legacy systems on CentOS. I rate this nine out of ten because I still think it is not perfect. Even though it is free and open source, it still needs some more robust features to compete with systems such as Red Hat or Ubuntu. Since we are not using Docker on CentOS for our production work, only for testing, if it could be more robust and scale its features, it could compete with Red Hat and Ubuntu, and then all of us could use Docker on CentOS for production too.
