We use Red Hat Enterprise Linux in the enterprise for production environments. We mostly use it on bare metal servers, which are dedicated. In terms of deployment, we use the on-premises version of Red Hat Enterprise Linux.

Red Hat Enterprise Linux has given us better insights and allowed us to manage the environment more effectively. In terms of overall performance improvements, it has provided us with increased visibility into security, which has been helpful for our cybersecurity team.

Its built-in security features seem pretty sufficient for our purposes, but we have other teams that manage the security and build aspects. I am more involved in the maintenance of it, but in terms of the built-in security features, I find it sufficient. The security team also takes care of the compliance aspect.

I mainly use the Red Hat database for vulnerabilities. It is pretty good for determining whether or not a vulnerability has been resolved. 

We use Red Hat Satellite for patching. I like Red Hat Satellite for patching and keeping us secure.

We have used Red Hat Enterprise Linux in hybrid environments. It seems to work fairly well. For hybrid environments, it is probably one of the easier ones to deploy because it allows us to scale.

We were able to realize the benefits of Red Hat Enterprise Linux immediately after the deployment.

In terms of the organization and structure, the support is on point. The reporting and other things are very standardized. It does not leave much room for error when working in production environments.

When we first deploy Red Hat Enterprise Linux, it is very challenging to determine which security features have been deployed. It would be beneficial to have more insight into this. Additionally, once it is built, there does not seem to be an option to retroactively change security features, which can make it difficult to ascertain which ones have been deployed.

Their knowledge base is very verbose. There is too much information. It can complicate things a little bit. It is very detailed. If they can shorten it, that might be helpful.

We have been using Red Hat Enterprise Linux for a few years now, approximately seven to eight years.

I would rate the stability of Red Hat Enterprise Linux as seven out of ten. We do encounter problems, most of which can be resolved. Occasionally, we face issues that cannot be resolved until the kernel developers address them. These are typically dealt with through quarterly releases or major upgrades.

In terms of scalability, I would rate Red Hat Enterprise Linux about a nine out of ten. It is easy for us to make snapshots when we are patching. If we need to clone, we can do so, although they might not be full backups necessarily.

We use their portal for contacting support. The support from Red Hat is quite quick because it operates on a service-level agreement (SLA). For the paid support features, they are very responsive.

Positive

I am familiar with CentOS, and I have used OpenSUSE and SUSE Enterprise for testing and comparison purposes.

CentOS did not have as many security features. Of course, CentOS had the community support. CentOS was bought by Red Hat, and then the support started lacking. It was then discontinued to promote Red Hat Enterprise Linux.

We have done some physical to virtual migrations using VMware. We have been mostly involved in that. We have done a little bit of virtual-to-cloud migration but not as much as physical-to-virtual.

The migration is more on the complex side. There are quite a few players involved. We need to collaborate with different teams. We need to make sure that the database is there, and that the database team is always involved. It is not terribly simple. It requires quite a bit of project planning and coordination. We usually have a six-month project so that it can be planned and tested.

It does require maintenance on our end but not very frequently.

Red Hat Enterprise Linux licensing is quite costly, but I personally do not deal with pricing.

My advice to new users would be to focus more on the build aspect because it can be overlooked by many new users.

The Leapp utility works well when you do not have a much-customized environment. The more customized your environment is, the more complicated it gets to get Leapp to work to switch over to Red Hat Enterprise Linux. It is possible, but the more customized your environment is, the harder it is because it will require the kernel module. Convert2RHEL is pretty much the same as Leapp. The more customized the environment, the harder it is. It is feasible. It is just a matter of how much time you are willing to spend on it.

I would rate Red Hat Enterprise Linux a seven out of ten.

I use Red Hat Enterprise Linux to control my Docker systems and build and run containers on them. I also use it for a tokenization project I'm working on.

Red Hat Enterprise Linux (RHEL) has improved the availability and security of our systems. The knowledge base, Wiki forums, and other resources are very helpful in simplifying my daily operations. We realized the benefits immediately after deployment. 

The most valuable features of Red Hat Enterprise Linux are the availability, file system performance, and overall system availability. The kernel is more secure than my previous operating systems, such as Windows.  Red Hat's knowledge base is helpful. I consult it several times in my daily work. I can ask questions on the forums and get help in my daily operations.

Using Red Hat Enterprise Linux's image builder is easy. I can use GitAI to pull any image I want to build on my system and reach into it using Red Hat. I use Convert2RHEL to publish my work on tokenization. I'm publishing more than 70 prints on my system daily, and saving this file. It's easy to use.

There are performance issues with the response time when accessing the console, but I'm unsure if that's Red Hat Enterprise Linux's fault or if it's due to the lack of CPU or memory on our machines. The enterprise interface could be improved. I can only use the keyboard to transfer files from one system to another. I want to use my mouse on the interface, not just scroll up and down. I would also like my logs archived as an RAR and sent to me. 

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

Stability is critical to us. Red Hat Enterprise Linux ensures our machine's availability and reduces the need for frequent restarts.

I have not contacted customer or technical support myself. Our infrastructure team handles any contacts with Red Hat support.

Positive

I have used Ubuntu before. Red Hat has a more robust knowledge base, and finding solutions to any problem is easier.

The infrastructure team handled the initial setup. I'm a software engineer working on my applications. The infrastructure team builds the machine, and I only use it. It was relatively easy, depending on the complexity of the deployment configuration. After deployment, we have maintenance on our machine if there are new patches to deploy. I have three machines, and each one is identical, with the same containers, so I don't need to do maintenance on our machines more than once monthly. 

It is important to use the knowledge base and familiarize oneself with key commands to gain more about Linux and ease its usage.

We use this operating system for our on-prem servers because it is more secure and reliable. We can install whatever application we want.

I chose Red Hat Enterprise Linux because it is more secure and reliable than other operating systems. Red Hat has a feature called SELinux. I always use it because it is more secure than the other operating systems. I am using it with most of the applications. It is our baseline OS for any application.

The built-in security features are helpful when it comes to simplifying risk reduction and maintaining compliance.

Red Hat has very useful documentation. I always use it when I face an error or something like that. It is very reliable, and I use it all the time.

Over the last three to four years, I did not work in just one environment. I worked in two environments, but all the time we used Red Hat Enterprise Linux, we got more security and reliability. We have seen performance enhancement and less downtime for our main application. There is more reliability and better performance. It has improved our environment. We now have better performance, more reliability, and more security. There is about 30% to 50% improvement.

I have previously worked in the banking sector for one of the banks. We can now configure Red Hat Enterprise Linux for PCI-DSS Compliance. It has improved in that aspect.

SELinux is valuable. The main reasons for using Red Hat Enterprise Linux are security, reliability, and efficiency. The system is very reliable, and it is more efficient than others.

It is not very easy to manage because it has a command line interface, and it can be a little bit confusing from one version to another. For example, the administration of Red Hat Enterprise Linux 8 is a bit different than Red Hat Enterprise Linux 9. It is a little bit hard but not that much.

The GUI experience can be better. They can make it easier to access files and copy them. We should be able to do that without the command line. For example, if you compare it with Windows, Windows is easier to use. They can just simplify the user experience.

I have been using Red Hat Enterprise Linux for three to four years.

It is stable. I would rate it an eight out of ten for stability.

I did not face any issue with scalability, so I would rate it a nine out of ten.

We implemented it at the HQ and the DR site. We used it at two locations. We had 100 to 200 users using these servers.

I have experience with Windows Server. From a security perspective, Red Hat Enterprise Linux is more secure. From a performance perspective, Red Hat Enterprise Linux has better performance, but from the ease of management perspective, Windows is better.

The installation at the application layer is a little bit complex. The duration depends on the application, but most of the application takes months. Implementing an easy application or service, such as a web service, takes two to three days.

When it comes to the management, I manage it locally. I go through SSH on the command line and manage it. For security patching and updates, most of the time, I use Red Hat Satellite. It is a product from Red Hat for managing updates. Red Hat Satellite is easy to use and very helpful. I have upgraded from Red Hat Enterprise Linux 7 to Red Hat Enterprise Linux 8.

When it comes to security patches, they require a restart. That can cause some downtime.

I do not have much knowledge of licensing. That is handled by the procurement team, but I know that it is expensive. If they can provide more licensing options, it will be much easier for companies to buy.

I would recommend Red Hat Enterprise Linux because it is more secure, reliable, and scalable.

I used System Roles two years ago. It was simple to use System Roles. I succeeded in implementing them, so it was simple. They can be managed, but I used them only one time, so I do not have this much experience with them. 

I also used a service called Cockpit. It was easy to use. It was very helpful and easy.

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

I work on SAP HANA, which is on Red Hat Enterprise Linux.

Red Hat Enterprise Linux has a good support portal that I rely on.

The system rules are helpful for segregation of duties, as they provide us with more feasible access to the system, allowing us to register it accordingly.

We immediately see the benefits of Red Hat Enterprise Linux.

From an administrative perspective, the cloud platform is the best because we don't have to wait long. It's a portal, so we can access whatever we want through it, whether the Azure portal or the AWS portal; we click, and it'll purchase it for us. Some deployments take 30 to 40 minutes. But in most cases, especially for small services, it's just a few seconds to three minutes. From a business perspective, the pay-as-you-go concept is where we only pay for what we use. So those are the two things I like most about the cloud version of Red Hat Enterprise Linux.

Using Red Hat Enterprise Linux on the cloud can become costly over the long term.

I have been using Red Hat Enterprise Linux for six years.

Red Hat Enterprise Linux on the cloud is stable with a 99.9 percent uptime. Regional redundancies are used to ensure data accessibility.

The initial deployment was a little challenging until I became familiar with the solution through the portal. We did encounter a handshaking issue with Azure that required submitting a ticket to Microsoft, but otherwise, the process went smoothly. A team of four were involved in the deployment.

The implementation was completed in-house.

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

We have to apply patches weekly, monthly, or quarterly, depending on their purpose.

We had no concerns about using Red Hat Enterprise Linux in the cloud because both AWS and Azure supported it, and they provided support if needed.
