We predominantly use Red Hat CoreOS we use it to connect to different types of OpenShift clusters. Whenever I work with RHEL, it's always been with the CLI.
Previously, when we were using other distributions, we weren't getting a lot of support for the operating system itself. However, Red Hat has mainly focused on the operating system, so we get more support.
AWS has its own version of Linux for its instances. All these cloud providers provide more support for the infrastructure and services, but they don't focus on the operating system itself. But Red Hat, with its customer portal, provides better support if something goes down. That's what differentiates RHEL from other products.
One great thing about RHEL is that it has a big community of users. There's a huge community that uses CentOS. If you need some help or have a question online, you get more resources for RHEL compared to other products.
It's a really good operating system by itself. It's more versatile, integrating with tools like Ansible for automation.
There are amazing resources online, and because we are an enterprise, we have enterprise support. We can always create a support case, and we have some resources to help. The knowledge offered by Red Hat is great.
Another feature I tried was RedHat Insights because they offer it for other RedHat products as well. I've used it for OpenShift. It was helpful. It provides a good, in-depth understanding of what's going on in the actual infrastructure. It gave us good insights into the level at which we can run the containers and if you can scale the infrastructure vertically or horizontally and how to manage it better.
There is room for improvement in integration with different cloud platforms. There should be better integration because right now, a lot of cloud platforms have their own versions of Linux, which runs better on them, and they have better integration with the services. RHEL is great, but RHEL is more of a generic form of what Red Hat provides.
I've been using RHEL for about four years now.
There were certain times when I encountered issues. There are certain problems with integrations.
For example, we had an issue once where the operating system had issues accessing the data server on our VMware infrastructure. So we did have a couple of engineers help us out with that, but that's one area where it can improve. But that's nitpicking.
It's been great so far, but that's one thing I would like to see that would make RHEL a little better product.
We prominently use RHEL, but we've also used Ubuntu. We also have used PCF. I use Ubuntu Xenial and have worked with Amazon Linux for a while.
One pro is that at the operating system layer, RHEL has better support from Red Hat, and if something goes down, I found many resources for troubleshooting online.
For example, we predominantly use Amazon Linux if I'm using AWS. There aren't a lot of resources if I run into an issue. RHEL has way more documentation on Linux. It has a bigger community, from an operating system perspective.
One of our deployment models is on-premise, and the other is on the cloud. It's a hybrid. We have a big footprint on the cloud.
We use Azure because a lot of resources are already deployed on it. We can use all the features I build on RHEL, but you can scale up the infrastructure, depending on the demand. That's the reason why we use Azure.
For the upgrade process, we mainly use Ansible automation. Whenever we want an upgrade, we just go into the Ansible Tower, change the version, and make sure we are applying that to the right environments so that there's no outage.
Overall, I would rate the solution an eight out of ten.
