Featured Reviews

Mohammad Wasif - PeerSpot reviewer
IT Infrastructure Engineer at Trigyn Technology
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.

Software Engineering Manager at Visteon Corporation
Role-based automation has streamlined secure CI pipelines and supports data-driven delivery decisions
Any product that I create, I will have an improvement expectation for Jenkins on Hardened Ubuntu. The one expectation that I have is that the UI can be still improved. Some more metrics can be established. Nowadays, there are a lot of configurations. I should be able to really connect with AI as another feature that can also be integrated. These are the three or four items that can be added to the improvement toward Jenkins on Hardened Ubuntu.Jenkins on Hardened Ubuntu could include AI chat features in the future to make it even better. When there is a build happening or when there is a job happening, I could ask in the chat how long that takes or what is the current job running. These AI features can be included.
