What is our primary use case?
CentOS 9 is still in use in my infrastructure operations and support coming from a traditional data center background. I utilized it extensively in projects from 2022 to 2024, including retailers and Volvo, where application isolation was a key consideration during the discovery phase. During that time, legacy systems running on versions 6 or 7 were successfully migrated to the latest upgraded version of Linux, demonstrating my experience with the latest Linux version.
For 2025 and 2026, I have proposed using CentOS 9 | Support by SupportedImages 25 for NHS in my solution. This includes determining required CPUs for applications categorized into Silver and Gold based on their performance, latency, and other factors. I also provided detailed technical information on how to manage essential secrets.
With container management in CentOS 9 | Support by SupportedImages, I participated in a project involving microservices architecture, where we introduced containerization and Docker services, along with Kubernetes as an orchestration tool. We also explored OpenShift as an open-source alternative, demonstrating my involvement in these areas for a postgraduate loans initiative in the student loan company.
What is most valuable?
My favorite aspect of CentOS 9 | Support by SupportedImages revolves around its performance in distributed systems because it is open source.

Regarding security in CentOS 9 | Support by SupportedImages, I emphasize that managed services' shared model relies on hardening your system. Implementing NIST CIS control levels 1 to 7 is crucial, addressing role-based access control, DDoS attacks, and various cyber threats, demonstrating the significance of security within Linux systems.
What needs improvement?
Among the downsides of CentOS 9 | Support by SupportedImages, I find that while installation becomes easier, the migration process concerning mainframes has been well-represented, especially with CentOS 9 | Support by SupportedImages 10 now integrating AI capabilities. The inclusion of GPUs and other resources to process large datasets could be a future direction worth pursuing, enhancing its abilities with RAG or generative AI through proper prompt engineering and ethics considerations.
I would prefer to see more AI integrations within CentOS 9 | Support by SupportedImages. IBM is already making strides in this area by investing significantly. Following their acquisition and merger with Red Hat, CentOS 9 | Support by SupportedImages distribution aligns closely with Red Hat's, fostering AI capabilities and a futuristic approach to enhance daily operations through flexible application building on virtual machines.
For how long have I used the solution?
Throughout my career, I have used Enterprise Linux with Satellite, where CentOS 9 | Support by SupportedImages served as an upgrade of 8 at the enterprise level. In my projects during 2022 and 2024, I managed to migrate nearly 2,000 servers to the cloud, with CentOS 9 | Support by SupportedImages being the latest version I utilized at that time.
The last time I used CentOS 9 | Support by SupportedImages was in 2024, specifically with Volvo. Additionally, there was a proposal to transition NHS applications onto the Linux platform aimed at unifying legacy applications with Linux as the operating system. We identified several legacy systems where applications required authorization and authentication within specific user groups, and this proposal was made at the enterprise level for NHS to enhance system visibility across the UK.
What do I think about the stability of the solution?
I experienced some lagging or crashing when I migrated to CentOS 9 | Support by SupportedImages 8; this event occurred during the early stage of that version.
What do I think about the scalability of the solution?
CentOS 9 | Support by SupportedImages operates effectively within a distributed system. Scalability and autoscalability allow for adding or removing instances as demand fluctuates, emphasizing the flexibility of CentOS 9 | Support by SupportedImages in modern infrastructure.
