Its use cases include general system management, setting up service with the web server, setting up a virtual, private wall with OpenVPN and FTP servers, etc. I have been working with all the aspects of the system in general.

The stability and the number of users that can access the servers are some of the valuable features. 

The stability of Red Hat Enterprise Linux is most valuable. I have machines running and working for hours, weeks, and months. The servers don't go down. In Windows, too many services hang, but in Red Hat Enterprise Linux, the servers continue working for months. I have had to reboot the machine only two times in years. The system keeps on working. So, stability is the best feature. 

Red Hat Enterprise Linux is very secure. There hasn't been any successful attack from hackers in years. It's one of the best features. The iptables command is helpful for setting your firewall policies. Only the machines that have the permissions can access the box.

We have had issues with the identification of new volumes when you add new disks or storage. You need the remove the machine, which can cause problems when you have high availability. If they can resolve the problem of detection of new volumes, it would be good for system administrators.

I've been using Red Hat Enterprise Linux since version 6.

It's very stable.

I don't have direct contact with their support, but I know that their support is good because I know people who work directly with their technical support.

I've worked with Ubuntu, Debian, SUSE, and other companies. In the past, Debian was the better operating system for servers and Red Hat Enterprise Linux was the better system for desktops, but nowadays, Red Hat Enterprise Linux, CentOS, and Oracle Linux are the better system for servers in my opinion, and Ubuntu is better for desktops.

This operating system is used by our clients. We don't have it in our organization. We use Windows. I'm not the one who decides about this. My director is the person who take decisions, but I prefer Linux. I like Red Hat Enterprise Linux in servers because there is support, stability, and more users that can access the service. However, in our organization, we use Microsoft Windows because they are partners. 

Most of our clients are institutions or public organizations. They have their own infrastructure for security reasons. Having a cloud environment has its own advantages and having your own infrastructure has its advantages. I prefer having my own infrastructure. When you have your own infrastructure, you have more control over all the processes and data of your organization, but I understand that having a cloud setup has advantages because you can manage and automate several systems or processes in the organization.

It's easy to install Red Hat Enterprise Linux. It's not difficult to install. You have the typical steps of the installation of any Linux-based operating system. Anyone can install this operating system. If you want to install servers such as an Apache server or a web application server, you need certain skills, but the installation of the operating system is easy.

I don't know about the pricing because I am not responsible for taking decisions about products used in the enterprise. Our clients use this product, and we use this product with the clients. In my home office, I use a free operating system. There is no support, but I can use it to practice. Our clients need support because it's used in the production environment. I don't know the price of the product, but I understand that with the support that Red Hat offers, compared to other operating systems, Red Hat Enterprise Linux is cheap.

It's easy to install and secure. You can customize it and manage various aspects. It's a good operating system for servers with security. It can run on machines without a powerful CPU or a lot of memory. It's stable.

Overall, I'd rate Red Hat Enterprise Linux a nine out of ten.

We are using Red Hat Enterprise Linux for running solutions, such as database solutions, and enterprise, web, and network applications.

One of the fundamental reasons Red Hat 7 has benefited our organization is that it is fully certified. It has certifications on the DISA STG and other cybersecurity frameworks like Zero Trust. This is what the Department of Defense mandates to be used and it is feasible to receive these specifications and automate the implementation for continuous improvement. By implementing the technical guides, we can receive immediate results and protect environments according to our expectations. There are a group of technical procedures that are shared and that you can implement, if you follow the industry best practices.

The most valuable features are the specification and technical guides, they are most important for cyber security assurance

The accessibility to the resources could be more widespread. The registration of the license information is complicated and this product registration process should be easier for customers to access.

In an upcoming release, they could improve by having more focused security.

I have been using Red Hat Enterprise Linux for more than 15 years.

The solution is highly stable.

Red Hat Enterprise Linux is perfectly scalable. You have some resource limits depending on how you're using the technologies. According to those usage patterns, the system is going to be able to give more or less. However, this depends more on the user side than on the system side.

We have approximately 10,000 enterprise users using the systems. They sporadically log into the applications and make use of the database systems and extract information. 

There is a division between the paid support and the support that is included by the website of Red Hat. I have only used the website support and there is a lot of documentation available.

Positive

I have used other Linux products, such as AWS Linux, Debian Linux, and Ubuntu.

The initial setup is straightforward for our use case. As long as you understand what you're doing, the technologies that are involved, the proper way to style, secure, and prepare them, everything will be fine.

After you have the guide, the printed procedure, the deployment is straightforward. The operating system can be deployed in less than an hour.

Okay, and how long did the deployment take?

The solution requires maintenance, and it is a shared responsibility. They take different maintenance actions or tasks, and sometimes it's the operating system, database system, or application front band that needs maintenance.

The number one advice would be to keep the division between testing and production.

There's one system that you need to set up for testing purposes only, and this testing system can be obtained free of license. There's an evaluation license that can be easily applied. When developing the application on the Red Hat 7 system, stay using the evaluation version until the requirements are fully met, only then should you migrate them to a paid supported version.

The biggest lesson that you learn by using this solution is, you easily reach a point where a single person or a single team can no longer respond to the complexities and challenges of the security or the different versions of the applications. At that moment you need to rely on a serious fused team, that team that is backing the effort.

I rate Red Hat Enterprise Linux an eight out of ten.
