Modern infrastructure has supported cloud migrations and improved secure distributed workloads
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.

Containerization has accelerated testing cycles and consistently reduced time to market
Docker on Ubuntu 18.04 LTS is a very mature product, and I don't think there is a lot of improvement that they need to do on their end. The Docker team is coming up with new features, and integration with the IDE, for example, would be amazing. Support on Windows is not so great from Docker, so that is something that they could examine. I chose nine out of ten for Docker on Ubuntu 18.04 LTS because I think they could improve a little more on optimization. It sometimes demands a lot of RAM and computing power, so that is one area that the Docker team could improve upon.
