Best Linux OS - RHEL
Adapts well to varying needs, and it's very stable and cost-effective
What is our primary use case?
How has it helped my organization?
Cloud-based Red Hat Enterprise Linux deployments provide cost savings. If customers are purchasing a physical server, they need to have a proper setup. They need to have a data center, cabling, and a lot of other things. For cost-saving purposes, they are going for a cloud. As an operating system, it offers the same functionality on-prem or on the cloud.
What is most valuable?
It saves money for company owners. It helps our customers save money and do things quickly. They can build servers quickly. There is a menu where they can fill in the VM name and other details and attach storage. In ten minutes, they have a server ready.
I am Red Hat certified. I train people in corporations and educational institutes. Red Hat's material is very good. Their testing system is awesome. If someone is certified in Red Hat, you know that they know it well. There are millions of videos on YouTube, but they are not always updated. On the Red Hat site, the documentation is very clear. You just need to focus and study for two to three months to get certified.
What needs improvement?
Nowadays, delays are common with their support, and it often takes time to get assistance from experienced engineers.
For how long have I used the solution?
I have been using Red Hat Enterprise Linux for seven to eight years.
What do I think about the stability of the solution?
Red Hat Enterprise Linux is an excellent product, and its stability has improved significantly over time. It can operate for extended periods, like six months to one year, without issues.
What do I think about the scalability of the solution?
Red Hat Enterprise Linux scales well with increasing user demands or infrastructure size. It is easily available and efficiently adapts to varying needs.
Most customers host medium-sized applications on the cloud. Storing a big application can lead to higher costs.
How are customer service and support?
The technical support from Red Hat has declined over the past four or five years. It could be because there are not many skilled people. When we raise a case, it is attended by junior people or new people, which wastes two to three days. We might even have to raise the severity of the ticket. However, when senior people take ownership of the case, the support is awesome. They give proper support. This was not the case earlier, so whenever we raised a ticket, we got an immediate response from Red Hat.
How would you rate customer service and support?
Positive
How was the initial setup?
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.
What's my experience with pricing, setup cost, and licensing?
I did some research on pricing a long time ago, and at that time, it was much cheaper than Windows. I do not have current details about pricing, but it is affordable.
What other advice do I have?
Overall, I would rate Red Hat Enterprise Linux a ten out of ten.
Which deployment model are you using for this solution?
RHEL one of the best distributions out there, highly recommended..
