The initial setup is smooth.
We have Cloud-based deployments. We are using AWS, GCP, Azure, and other cloud platforms. We also have on-premises deployment. Some customers also have a mixed deployment with the cloud and on-prem but in such environments, I have seen problems in terms of performance. For example, if my database is on-prem on Red Hat Enterprise Linux, and I am storing my application on the cloud on Red Hat Enterprise Linux, whenever someone hits the website, there will be latency issues. I sorted out such issues for a customer. I suggested they migrate their server from the cloud to on-prem because their database was quite big. With a mixed setup, they were having a lot of issues in terms of performance and storing data. It was very slow. After they moved it on-prem, it was much faster. This is not a Red Hat-related issue. From the operating system side, no improvements are required. However, cloud providers need to improve their facilities.
For patching, I use Red Hat Satellite, and for configuration, I use Red Hat Ansible. Leapp upgrades are also awesome. A month back, I upgraded Red Hat Enterprise Linux 8 to Red Hat Enterprise Linux 9. I created detailed documentation about the procedure. There were about 14 steps. It was straightforward.
With Red Hat Insights, we can see the security threats. Red Hat Insights is integrated with Red Hat Satellite. It will be helpful from the patching point of view. It lets you do subjective analytics of servers.
