We had a lot of IBM AIX servers. We migrated a lot of them to Red Hat Enterprise Linux. We have a lot of VMs, and we have a few physical servers. Currently, we are moving all the Red Hat VMs to the cloud. There are 1,600 to 1,700 Red Hat VMs that we are currently running.

Secure, easy maintenance, and good support
What is our primary use case?
How has it helped my organization?
The main benefit is that it can be easily recovered and easily restored. It is on the VM. We can easily restore every image that we back up on the VM. If something happens, we can easily fix it. Support and maintenance are easy. The most common issues that happen with Red Hat Enterprise Linux are password restore issues. We can go and restore the passwords through the single-user mode. This feature is well-developed and good.
We are using Ansible for the most automations. We can push everything through Ansible. We are moving towards automation to make sure our system can be easily maintained, and we can recover, restore, and do the things that we want. We have 1,600 to 1,700 servers. We have Ansible Tower, and we have a few satellite servers and a lot of capsules to support Red Hat servers.
If anything is supported by Red Hat Enterprise Linux and the feature is available in Red Hat Satellite, we are able to install it on Red Hat Enterprise Linux. We are using Red Hat Satellite to install all the patches and all the packages, so if a feature is available, we can easily install it if it is supported.
Red Hat Enterprise Linux has built-in security features for simplifying risk reduction and maintaining compliance. We are working with most of the security environments. Security is our main concern. We have zero tolerance when it comes to security. We are able to apply security rules and regulations within the Red Hat environment.
What is most valuable?
We are using Red Hat Enterprise Linux 7, and we normally look at how it can easily support the system. With Red Hat Enterprise Linux 7, we have a high-security system. We have a lot of features there. That is the main thing, but currently, we are moving from Red Hat Enterprise Linux 7 to Red Hat Enterprise Linux 8.
Red Hat Enterprise Linux Leapp and Red Hat Insights have been useful. RHEL Web Console is also helpful.
We have access to the Red Hat knowledge base. We have frequent meetings with Red Hat. Red Hat partners provided us with all the information and any kind of training.
What needs improvement?
We are using the features that are available with Red Hat Enterprise Linux and Ansible. As such, there are no specific features that we are looking for.
We have frequent meetings with them. We have had some issues on the application side and the OS side for which we opened cases and discussed those concerns and questions in the meetings offered by Red Hat.
For how long have I used the solution?
I have been using Red Hat Enterprise Linux for almost 10 years.
What do I think about the scalability of the solution?
Upgrades and migrations are ongoing processes to stay current. We are a big company. We always have migration going on. We always have the build process. Red Hat's presence keeps increasing in our environment. We are going to have about 2,500 Red Hat Enterprise Linux VMs in the next year.
How are customer service and support?
If there are any concerns, we have a meeting with Red Hat, and they provide the required support. When we have any concerns or questions, they answer them. It is easy. I would rate their support a nine out of ten.
How would you rate customer service and support?
Positive
What was our ROI?
We have probably seen an ROI. Red Hat is getting better every day.
What other advice do I have?
Overall, I would rate Red Hat Enterprise Linux a ten out of ten.
Offers efficient performance tuning capabilities, enhancing overall system performance
What is our primary use case?
My use cases are mainly limited to databases. I'm also involved in other ETL tools; I worked on migrations from older vendors, like Windows, and transitioning to RedHat Linux.
What is most valuable?
The most valuable features are security, performance tuning, storage management, and OS-level automation. If you wanted to automate while adapting with different vendor scripts or your own development because it's Linux, it's not like an operating system itself. It is always going to perform how you expect it to. IAQt's not like other operating systems. It is based on Linux.
These are the main features. Storage management is another valuable feature that is very critical in an operating system. It works along hardware and software.

Compared to other OS', Red Hat Enterprise Linux is the best from my 20-plus years of experience. It is well-suited for production environments. In 2003 and 2006 I worked with one of the vendors in another country. We were able to run a database instance on Red Hat Enterprise Linux for two years without restarting it. The database was located in a remote location, and the team could not be on-site to provide support. We installed it ourselves and it worked for two years. We restarted the database instance. We didn't need to touch it internally. It works like a charm.
If it works, it works. You don't need to attach anything at all. You just monitor them remotely. Nobody was there on-site. That's the beauty of it. Red Hat Enterprise Linux is great. I love it.
What needs improvement?
The GUI has room for improvement. It needs to be managed by many administrators. It has basic command lines. They could improve it with better automation. We'd like to be able to create a script, and then have the ability to deploy it where we don't need to write everything manually. That part can be useful for automating.
We'd like it so that a coder wouldn't need to go through it, read it, go to GUI, and then generate a script. If they want to modify it, they could modify it. If Red Hat Enterprise Linux is going to build something, the REST API can be helpful instead of writing their own, starting from scratch. That would make it easier.
For future releases, there could be more integration. Regarding security, we used a different tool for scanning, but having a tool within Red Hat could enhance it.
Support is essential for open-source software. If they improve aspects like prevention against hacking, it would be beneficial.
Before, with a surge in hacking incidents, companies lost data, and once lost, it remains lost forever. You never know when it might be used. Improving security, especially in terms of prevention, is crucial. I would like to see ongoing improvement in this aspect.
For how long have I used the solution?
I've worked with different companies. In my over 20 years of experience, in the last five or six companies I've worked for, all of them have been using Red Hat. They use it mostly for databases.
I'm in the database sector, primarily working as a senior technical architect. End-to-end, we always find that Red Hat is best suited for Linux, especially for Oracle and other NoSQL databases. It's reliable, first and foremost, and it offers stability and performance. Performance tuning is crucial, and once it's set up, you can rely on it.
With the cloud, it's moving into containerization, and most of them support the cloud.
How are customer service and support?
The customer service and support are really good.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
I have worked with many different operating systems in the past, including Windows, Linux, and RedHat Linux.
We switched to Red Hat Enterprise Linux because it is a reliable and well-supported enterprise operating system. It is easy to manage, use, and upgrade.
What was our ROI?
We have seen a return on investment.
What other advice do I have?
As a consultant, I handle sizing, design, and optimization for new infrastructures and I would recommend Red Hat Enterprise Linux to anybody considering it.
Overall, I would rate the solution a ten out of ten.
