SAURAB K GANGURDE - PeerSpot reviewer
Senior AWS Consultant at Quantum Integrators
“Amazon Linux delivers automated security updates— including live kernel patching in AL2023—ensuring protected workloads with minimal manual effort and zero-downtime patching.”
One improvement for Amazon Linux would be stronger support for running it outside AWS. Although Amazon provides local VM images for VirtualBox and VMware, they are intended mainly for development and testing. Unlike Ubuntu, Debian, or Red Hat, Amazon Linux is not designed or fully supported as a production OS in on-prem or hybrid environments. Expanding official support outside AWS would offer more flexibility for teams that maintain mixed infrastructure. Another area for improvement is the community ecosystem. Compared to Ubuntu or Red Hat, Amazon Linux has a smaller community and fewer third-party resources or tutorials. A larger ecosystem would make troubleshooting and adoption easier. Finally, improving backward compatibility between Amazon Linux 2 and Amazon Linux 2023—especially around package management (DNF vs yum) and updated toolchains—would simplify upgrades for teams managing large fleets.
Mohammad Wasif - PeerSpot reviewer
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.
