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.
reviewer2728158 - PeerSpot reviewer
Associate Cloud Operations Engineer at a tech vendor with 501-1,000 employees
Good compatibility and improvement needed in migration process
For long-term support, it has been good because in most enterprise environments, people still use Ubuntu Linux sixteen, which is quite obsolete now. Other enterprise versions do not support obsolete systems, so supportability is good in terms of Ubuntu Linux. For sustainability, it's quite a significant point of view for every organization. For us, Ubuntu Linux is the preferable way. For others, it might not be, so that is quite a subjective matter itself. The pinpoint of the problem is that they take time because they need specific information. We need to go to AWS first, and then they'll contact the Ubuntu Linux support team itself. This creates a two-way hop for us, which is why it's not that great. It's not really Ubuntu Linux's problem but rather the way we are accessing Ubuntu Linux. The migration part when migrating an application or one version of Ubuntu Linux to another is quite hectic. During the process, one or many applications might crash. That is something they could handle themselves, but I don't think that's something Ubuntu Linux will look into. During a migration project that I was handling, Ubuntu Linux was not completely compatible for the migration process from one application to another. This is an area they could improve in migrating from minor versions to major versions.
