Our environment is hybrid. Most of our Red Hat Enterprise Linux is on-prem. For the cloud, AWS is the cloud provider, but we are using a different distro for AWS. We use AWS Linux for that. For on-prem servers, we're strictly using Red Hat Enterprise Linux. For desktops, we use Fedora.
The reason for using AWS Linux is that we only have AWS. If we use multi-cloud, for instance, if we use Azure and AWS clouds together, we would definitely need something other than AWS Linux. AWS Linux is very solid too, and our team likes it. We can download the AWS Linux version for on-premises too. I've done that. I tested it, but we're sticking with Red Hat Enterprise Linux.
In the server space, nothing comes close to Red Hat Enterprise Linux. I know that Ubuntu is making a big push, and some people have gone ahead and migrated to Ubuntu, but I think those are going to migrate back. There's just no comparability. They're different. They're like cousins. They're very similar in some ways, but they're very different things. You can install SELinux on Ubuntu, but why bother and why go through the whole configuration? Red Hat Enterprise Linux is more suitable for servers.
