Red Hat Enterprise Linux 9 (redhat 9) Hardened

I am ready to shift from a project I was focused on, and I took a break recently. I stopped working with Red Hat Enterprise Linux while I was working with Ericsson Global Services Private Limited in India. I was in Sweden for a while, visiting three times. I left Ericsson about two years ago and have been working on freelancing since then.

I remain in touch with Red Hat Enterprise Linux as it is my core focus. I have been dealing with both versions 8 and 9. I am a user of Red Hat Enterprise Linux, and I work as a Linux administrator with RHCE certification.

I recently found features such as SystemCTL and the init process boot up to be significantly faster now. Cloud integration is quite easy, and containerization support along with file system level enhancements has improved considerably. The system is much more stable, including LVMs.

I utilize Red Hat Enterprise Linux 9's SELinux for enforcing security policies, which is quite advanced. It has helped considerably for securing the server in my organization.

To improve Red Hat Enterprise Linux 9, I suggest adding better features, patch management, and enhancing SELinux even further. Breaking SELinux is very difficult, but challenges still exist. Port management is somewhat challenging, and opening ports when SELinux is enabled can be problematic. Proper logging is needed when trying to run a service that requires a particular port.

I have been working with Red Hat Enterprise Linux for ten years now.

The technical support by Red Hat Enterprise Linux overall meets my needs quite well. The support engineers have good knowledge of the product, and whenever I seek support, issues get resolved.

There is room for improvement regarding response time and first-level support quality. I can now file support reports and get feedback online. Instead of calling, I visit the Red Hat Enterprise Linux website and open a ticket, which has become a seamless process.

My experience with the setup was that it was easy to set up and straightforward to use.

I did not use Podman in Red Hat Enterprise Linux 9 for container management, but I am aware it exists. I was using a VMware setup with OVF kind of images instead.

We have yet to fully assess Red Hat Enterprise Linux 9's integration with hybrid cloud technologies, but I have observed good features compared with version 8. I conducted a proof of concept with Red Hat Enterprise Linux 9 for integration with hybrid cloud technologies, though the scope was limited. When it moves into production, I will have a clearer understanding of its capabilities. Overall, the feedback and proof of concept outcome were successful.

I did not use open-source support in Red Hat Enterprise Linux 9. To measure the performance of Red Hat Enterprise Linux 9, I have CDRs pertaining to the application, where I input data to the server and measure the processing speed and output, tracking how many milliseconds it takes. The load on an idle server runs very fast as I provide it with a substantial amount of load, and I receive feedback on that.

I rate Red Hat Enterprise Linux 9 | Support by SupportedImages overall as an eight out of ten. To bring it closer to a ten, I would prefer to see advanced features such as Podman and other next-generation requirements, which already exist in Red Hat Enterprise Linux. Advanced-level Docker support is also available, and altogether, the system performs well. These features already exist and can be improved based on specific requirements, but as of now, what is needed in the real world already exists in the market.

We have a direct subscription through Ericsson, though I am uncertain whether they purchased it from the AWS marketplace, directly from Red Hat, or from a third party. I rate Red Hat Enterprise Linux 9 | Support by SupportedImages with an overall score of eight out of ten.
