Its SELinux feature is a gold standard for security
What is our primary use case?
We prefer Red Hat Enterprise Linux as our operating system due to its excellent support. If a business wants something, we deliver it and we prefer a Red Hat Enterprise Linux-based system because of the support. It can be a simple application to a big system. It doesn't have pre-defined roles. It's a go-to operating system.
Our use cases for it vary from plain operating system management to handling specific tasks such as running Oracle databases or other similar applications. They include quite a broad spectrum of requirements. Also, they are not limited to predefined roles but encompass the entire operating system infrastructure.
What is most valuable?
The solution's SELinux feature is a gold standard for security. It also has the best ecosystem.
In addition, its automation platform, ITM, is a good product and works well for us.
What needs improvement?
Some of the solution's features need to be automated. We encounter the hassle of registering the system and attaching a subscription. Our company has development teams, and we have to develop subscriptions for them. Here, having the solution up and running on the developers' machines is a bit of a hurdle. Although we can run it on platforms like Red Hat Connect but, it needs to be somewhat more accessible so developers can just download it and start with the work.
For how long have I used the solution?
I have been using the solution for 10-15 years.
What do I think about the stability of the solution?
What do I think about the scalability of the solution?
The solution is scalable when combined with automation features. I rate its scalability a nine.
How are customer service and support?
The solution's customer service is good.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
I have used Ubuntu, Fedora, CentOS, and macOS. Initially, I worked as a Red Hat Certified Administrator in RHEL 5. Later, I began to work for its partner company. That is how I switched to the solution. It was not a conscious choice. It just evolved that way.
How was the initial setup?
The solution's initial setup process is straightforward. You have to follow the steps, copy the template and multiply it.
What's my experience with pricing, setup cost, and licensing?
The solution's price is reasonable. If you have a license for the support, they provide excellent services. The support team is always available for help in case of errors or system downtime issues.
What other advice do I have?
RHEL’s built-in security features for simplifying risk reduction and maintaining compliance are good. If you keep SELinux on, it is all good. If you have a system with SELinux off for a long time, it could get you in trouble. The system will make many changes, like restoring files could break your application later. In case you resolve the problems simultaneously, it is fine.
The troubleshooting feature of Red Hat is excellent. It can solve many issues on the machine right away. In addition, if you have an external scene, then Red Hat Insights is on. I sometimes go to this feature to see its status and what is happening.
I don't do this on a daily basis and only check it every two weeks, but it's nice to have. I mainly oversee the high-level view of all the systems. This way, I know if the clients' machines need a patch system.
There are some missing modules for SELinux in Ansible, like the playbook. It becomes a genuine hurdle to manipulate SELinux at the moment. I have to go to the machine, take a file to the repository, and deploy it.
I rate the solution a nine out of ten.
Which deployment model are you using for this solution?
On-premises
A stable and secure solution that reduces risk and maintains compliance
What is our primary use case?
We're using the product to test operating system stability and verify that it runs on the hardware that Trenton Systems produces. If it passes testing, it becomes a validated operating system that we can sell for the server. We plan to offer Red Hat in the coming months to anyone purchasing systems from our company.
What is most valuable?
The solution’s security feature is the most valuable feature for my company. We offer OS to military or government agencies. For these sectors, security becomes one of the highest priorities, especially the ability to wipe everything out if anything becomes compromised. Red Hat does a great job at that.
What needs improvement?
The product should be made more accessible to someone who isn't experienced with Linux.
For how long have I used the solution?
I have been using the solution for four to five months.
What do I think about the stability of the solution?
The solution is very stable. Compared to many other OSs we test for our company, Red Hat Enterprise Linux has not crashed out on me or given me any problems. Anytime something goes wrong, after some research, I find that it's going wrong because I'm doing it wrong, not because the OS is fighting me in any way.
How are customer service and support?
I haven't used support where I'm emailing or speaking to someone directly, but I've used a lot of the online support just by looking at different user guides, health guides, and things like that. Everything is really well documented.
Sometimes there are posts about similar issues but with different remediation based on different circumstances. You might have the answer open in a tab, but you've got nine tabs open to find the right answer.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
I have used Ubuntu, CentOS, openSUSE, and Mint. Red Hat Enterprise Linux definitely has an edge in security and the ability to control what the user at the end stage is doing. However, it is difficult to learn.
What's my experience with pricing, setup cost, and licensing?
The licensing makes perfect sense for the number of features you get with the operating system.
What other advice do I have?
We test Red Hat Enterprise Linux 9, the latest version. We do backtesting for versions 7 and 8 as well. The product is very secure. It took me a while to wrap my head around the whole Subscription Manager system and understand how that worked. Even at a base level, it provides a much higher level of security and the ability to take remediation steps if things go wrong. You can shut the whole system down and bring it back from the ground up.
From the keynote, it looks like steps are already being taken to make the solution more accessible to any regular user.
The product does a really fantastic job of reducing the overall risk to the user. If a user is doing something they’re not supposed to be doing, it's very easy for the system administrator to walk them out of doing it. As for maintaining compliance, if a user is only meant to have specific packs and is only meant to perform specific tasks, it's very, very easy to lock it into only being able to do that one specific thing.
Most people in IT enjoy a little learning. Everything I've done so far with Red Hat has been installing, setting up the account, getting everything registered, and then worrying about testing to validate. It is difficult to start with, but the more you learn about it, the easier it gets. The more I use it, the more capabilities I find within the system.
Overall, I rate the product a nine out of ten.
Which deployment model are you using for this solution?
On-premises
A stable solution that can be used for a long time without having to upgrade every other year
What is our primary use case?
We use the product to host operating systems, applications, or infrastructure for our customers. Our customers use the product as a long-term solution that they don't have to upgrade every other year. They can get people that know the solution from the get-go.
What is most valuable?
The biggest feature is the longevity of the distribution. Compared to any other product, Red Hat Enterprise Linux provides a stable backported solution for a long time. It is important because we have moved a lot of software containers. We want to update it but don't want to unless we have to. So it's great to have something stable for a long time.
What needs improvement?
The biggest thing that the solution could introduce is an even slimmer version of Red Hat Enterprise Linux. We are moving to containers, but we also have a lot of void loads that don't go into containers. It would be nice to have an even thinner operating system. Even if you choose minimally, you still get a lot of useless stuff you don't need.
For how long have I used the solution?
I have been using the solution for 20 years.
What do I think about the stability of the solution?
I rate the product’s stability a nine out of ten.
What do I think about the scalability of the solution?
I rate the solution’s scalability a seven out of ten.
How are customer service and support?
It's really difficult to get to someone that knows something. When you get to the right people, support is really good. But there are a lot of people that can only answer first-level questions.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
We're using a lot of different OSs. We use Red Hat Enterprise Linux because we are a partner.
How was the initial setup?
It's pretty simple to install the product. However, some tools required to install it are missing.
What's my experience with pricing, setup cost, and licensing?
The pricing is great for virtual systems. The pricing for physical systems is way too high.
The overall costs depend on the project and the company.
Which other solutions did I evaluate?
We continuously evaluate other options. The main difference between Red Hat Enterprise Linux and other solutions is the complete ecosystem's longevity and possibility. Other products may present something similar, but they don't have the ecosystem around them.
What other advice do I have?
We probably purchased the solution from a cloud provider. We are using versions 5 to 9 currently.
The solution’s built-in security features are pretty good, but it's not something that I would take as a major selling point. The portability is good because we have a stable baseline for applications and containers. Red Hat Enterprise Linux’s security posture is pretty good. I don’t know if it's the strongest selling point, but it's up there.
In some ways, Red Hat Enterprise Linux enables us to centralize development. However, that's not mostly what we focus on. The primary output from Red Hat Insights is targeted guidance. Targeted guidance has not affected our uptime much.
It makes sense to go with a stable distribution compared to others. Overall, I rate the product an eight out of ten.
Which deployment model are you using for this solution?
On-premises
A top-notch solution that provides copious and high-quality documentation and saves time
What is our primary use case?
We installed the product at a very large hospital as their underlying operating system for Kubernetes, but it is not OpenShift. We use it for one-off servers and lab machines.
What is most valuable?
Copious documentation is probably the best feature of the solution. If you have a lot of high-quality documentation in one location, it is easier to search and get exactly what you need. It's more efficient when I get stuck on a problem or need help configuring something. It saves us time searching through Google or looking through GitHub Issues to solve the problems. It is a top-notch solution.
What needs improvement?
If the solution were easier to use and understand, it would not get disabled as often as it does. The solution should be made more secure. The changes made to CentOS make it hard for somebody to spin up and test it without having a preexisting relationship and license.
If somebody wants to get something going quickly and is trying to settle on Red Hat, they don't have a free version to go to. Ubuntu and SUSE provide such platforms to the users. It is one Achilles heel in Red Hat at the moment.
Even if Red Hat would enable a full version trial for people to test it, it would be less than what others are doing. Others are giving it away for free until you actually need support, and then you can choose if you need to buy it. With SUSE you can install it with SUSE Leap. It's pretty much the same thing. When you want support, you must enable support, and it becomes SLES.
There's nothing in Red Hat where I can run along on the free version for as long as I need to, and then when I want support, activate support on the same product. I have to reinstall it if I want Red Hat. Even with CentOS, it still wasn't possible to just activate it for Red Hat and make it become Red Hat Enterprise Linux. That's been something that's long been lacking in the product.
For how long have I used the solution?
I have been using the solution since 1996 or 1997.
What do I think about the stability of the solution?
I have no complaints at all about the stability of the product.
What do I think about the scalability of the solution?
As time goes on, the solution gets better. It adopts new features. I would say that it does a pretty good job.
How are customer service and support?
The few times that I've encountered support, it was great. I don't really go through support channels. However, when I reach out and ask a question to the people I know in support, I get answers pretty quickly. I find that they have a good deal of product knowledge.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
When I first started using the product in the 90s, it was just Red Hat. So I used Red Hat, and I used IBM Slack. I've used quite a number of different Linux distributions. Red Hat Enterprise Linux has been around longer than Ubuntu. I still use other solutions along with Red Hat Enterprise Linux.
How was the initial setup?
Typically, the initial setup is pretty straightforward. If it's virtualization, it is really easy because we have an image already, or we can create one. We can use Kickstart. I used to run a 5000-node HPC cluster in the early 2000s based on Red Hat Enterprise Linux. We used a combination of SystemImager and Kickstart for it.
What other advice do I have?
It's the default posture of a lot of the third-party vendors that you should just disable and leave them off. With containerization being prevalent everywhere, portability is across the board. Red Hat Enterprise Linux adopted Podman as opposed to Docker. Podman is a good tool, and I like it. Red Hat Enterprise Linux is the standard on which many others have based their platforms.
Using SELinux is largely misunderstood. If used properly, it provides a great platform for us. Red Hat is a big corporation, and we have people we can reach out and talk to. The same goes for SUSE. For Ubuntu, I have always gone straight to NVIDIA for support. I personally don't know of any great differentiators between all the products. I know Red Hat. It's been around longer, and I've had a long history that makes me comfortable.
I wouldn’t recommend one over the other. It would come down to the use case. If someone wants Kubernetes on-prem, I would probably guide them toward OpenShift. I do have customers that don't run OpenShift on-prem. I often find that the customers already have a preference because they already have a license. So it's never really a decision that falls on me.
Red Hat Enterprise Linux uses firewalls, so configuring a firewall is easy. I have deployed the solution in multiple places. Overall, I rate the product an eight out of ten.
Which deployment model are you using for this solution?
On-premises
The Podman feature is most valuable as it allows you to recreate images
What is our primary use case?
There are multiple use cases, and I am mostly focused on information security. Before we promote an ACS policy to production, we should be able to test that build and see how that policy behaves for that build. We use Podman to build some test images and get them to our development box. Then we use commands that we scan against those images. That has been one of the major use cases.
In the future, we'll move our automation program from an on-premises Windows server to a Linux server. Over a period of time, we want to move those applications to the cloud and OpenShift. Currently, we have many legacy applications that are still being run on Windows Server, and we use the title job scheduler for that. Once we mature and gain more confidence, we want to containerize those applications and move them to OpenShift and Linux.
What is most valuable?
Red Hat Enterprise Linux's most valuable features are the Podman and a lot of packages that come inbuilt as part of the regular package. Podman gives you the opportunity to build those images. Since it's a public registry, you cannot pull those images from a docker, and proxy blocks that. If we know how to recreate that scenario, we use Podman to recreate that image.
What needs improvement?
Red Hat Enterprise Linux should provide more training because many people are not very familiar with Linux's user interface. If it is made very similar to Windows and people can relate to it, they would be more comfortable.
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 a stable solution.
How are customer service and support?
I have experience interacting with Red Hat support for ACS. The initial level of support is very minimal. They try to collect all the data, then go to developers or technical people, which usually takes time. So we don't get an immediate response. Hence, there is scope for improvement in Red Hat Enterprise Linux's customer support.
Raising a ticket and having somebody look into it takes time. I rate raising a ticket and addressing it a six to seven out of ten. However, we interact with a responsive relationship manager, who escalates and gets issues fixed. I rate this relationship manager an eight out of ten.
How would you rate customer service and support?
What was our ROI?
Since we have the capability to test vulnerable images, we know much in advance what their impact will be. We can test ACS policies against those vulnerable images. That gives us early visibility instead of deploying that application and finding what is happening there. Using Red Hat Enterprise Linux and all associated components gives us that visibility into vulnerable images, and we can set policies based on whatever we see. So in terms of business impact, we avoid many vulnerabilities that get into the production.
What other advice do I have?
We run some applications on the cloud, but they are not business-critical applications. We run all business-critical applications on-premises. We are not dependent on the cloud for business-critical applications. We are not locked with the vendor.
We use Qualys to scan the underlying node. We expect any critical vulnerabilities to be patched as early as possible. We have an enterprise policy wherein any business-critical vulnerabilities seen on business-critical applications or nodes need to be fixed within 30 days. If some running application is exposed to the internet, we want that to be prioritized. If vendors can prioritize a 30-day life cycle for critical vulnerabilities, that would really help many other organizations.
Red Hat Enterprise Linux is the only option we are currently looking at. We don't want to go with Windows. We already have this ecosystem where we use OpenShift, and it's already integrated with ACS. So we would not like to go with any other different OS. Red Hat Enterprise Linux will integrate easily with the entire ecosystem.
Overall, I rate Red Hat Enterprise Linux an eight out of ten.
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)
We can dynamically expand volumes and easily scale, and the solution offers excellent support
What is our primary use case?
We are currently using Red Hat Enterprise Linux's versions 6, 7, and 8. We run the OS both on-prem and in the cloud.
We use Red Hat Enterprise Linux for web applications, containers, Kubernetes, and simple scripting servers. The scripting servers are used to run scripts on run drops and so on. However, the biggest use cases are containers and web app workloads.
The cloud providers are AWS and Alibaba.
How has it helped my organization?
Red Hat helps our organization avoid cloud vendor lock-in because we can run Kubernetes and a few different workloads directly on Red Hat across different cloud providers. Since Red Hat is an operating system, we can migrate our workloads to any cloud provider that supports Red Hat.
Avoiding vendor lock-in and being able to move workflows between cloud providers has saved us hundreds of thousands of dollars per year.
Red Hat Enterprise Linux is easy to recover, especially from a backup. I believe this is because of its resilience. If I use an instance, I can go to my backups and restore it without much trouble. I was going to compare it to Windows for a moment, where there might be some additional steps required to clean things up after recovery. However, I haven't had many issues where I needed to do any cleanup afterward.
It is easy to move workloads between the cloud and our data center using Red Hat Enterprise Linux. The ease of migration depends on the cloud provider and what they allow us to do. However, for the most part, replication-based migration between cloud providers or on-premises works well.
What is most valuable?
Linux is good for hardening the operating system. Logical volumes allow us to dynamically expand volumes, which is valuable from an operational perspective. This is especially true in cloud environments, where we pay for every kilobyte of storage. By using logical volumes, we can expand the disk on demand without downtime, which can help us keep costs down.
What needs improvement?
The price has room for improvement.
For how long have I used the solution?
I have been using Red Hat Enterprise Linux for three years, but I have known about the OS since version four.
What do I think about the stability of the solution?
Red Hat Enterprise Linux is definitely resilient and easy to recover, especially when compared to Windows. I enjoyed working with Red Hat Enterprise Linux more than Microsoft Windows, especially because of its resilience.
What do I think about the scalability of the solution?
Red Hat Enterprise Linux's scalability is easy to manage. We can simply spin up more instances as needed, and then turn them off when we no longer need them. This means that Red Hat Enterprise Linux's scalability is not as much of an issue with the cloud provider.
We have around 2,500 instances of Red Hat Enterprise Linux in our environment.
How are customer service and support?
Red Hat support is generally good, but it can sometimes take a little longer than we would like to get a response, especially when the issue is through a web-based chat.
How would you rate customer service and support?
What's my experience with pricing, setup cost, and licensing?
The on-premises deployments are subscription based, and the cloud instances are from the providers which are AWS and Alibaba.
We can always ask for Red Hat Enterprise Linux to be less expensive but when we compare it to other options, there are savings in the long run.
Which other solutions did I evaluate?
Red Hat Enterprise Linux was our first choice because of its enterprise support. That was the key factor. We do also run other Linux distributions, but Red Hat Enterprise Linux is our primary choice because of the enterprise support.
The big difference between Red Hat Enterprise Linux and other Linux-based operating systems is the support. There isn't much difference other than the syntax, where the command is "at, get" versus Red Hat using YUM or DNF for installation. So outside of that, the support is the main difference.
What other advice do I have?
I give Red Hat Enterprise Linux a nine out of ten. No solution is perfect, but Red Hat Enterprise Linux is very close.
Our engineering team probably used the image-building tool. I am on the operations side, so I do not see that part of the process. I take the images that are already built and deploy them.
I think it's just a workflow issue. We need to improve our own workflows to be able to manage them better. Red Hat support is already good when we encounter something we're unfamiliar with. So, we need to get Enterprise CoreOS from Red Hat for those cases. I think as we encounter more of our own workloads, we'll need to improve our workflows even further.
Which deployment model are you using for this solution?
On-premises
Fair licensing cost, highly scalable, and helpful for standardization and compliance
What is our primary use case?
We use it to host applications, services, and backend databases. We aren't using it on the cloud. Most of my customers are DoD or some type of government agency. If it's not classified, it's siloed in some way. We don't get to use a lot of the functionality that makes Red Hat cool. It's all disconnected.
In terms of version, currently, mostly everything is on versions 7 and 8. I've started pulling up some of the things from version 9, but that won't go into production for a while.
How has it helped my organization?
We use it because it's stable. That's half the reason, and the other half is because the DoD standardizes on it because it has a support contract, so even though we're forced to use it, it's a very good product, and it's on-prem. We probably would use it anyway.
We needed to host applications, services, and backend databases. We have a lot of Java-based applications, and we wanted something that we could deploy in different places around the world and that everybody standardized. Windows didn't really work for us on that. Most of the time, we're not connected to the Internet. We find that Red Hat or Linux in general works a little bit better for us than macOS or Windows.
It's also across the board a little bit cheaper for what we're using it for. That's a benefit we're getting from it.
We get our compliance from DISA, which is the defense information service agency. They put out security technical implementation guides. There are specific ones for Red Hat Enterprise Linux 7 and 8. The reason we're not using Red Hat Enterprise Linux 9 is that there isn't one for it yet. In terms of how we harden the operating system we're using, it's whatever they tell us to do and then whatever extra we want to do. It's as good as any other Linux other than the fact that it's supported by the DoD. For example, SELinux helps us secure across the board with contacts across different directories and things like that. They tell us how standardized the SD-WAN layout should be. We're able to go a little bit deeper into that. Red Hat uses Podman, which has SELinux, and which by default helps us a lot.
What is most valuable?
We run Satellite on a lot of these, so having a central repository that we can use for patch management and remote execution is huge. That's something that is very difficult in a Windows environment. We're very compliance driven, so to have that built into Red Hat is easy. We don't need an agent or anything like that to get a lot of work done, so Satellite and centralized automation are the most valuable features for us. We're dabbling into Ansible but not as much as we should be.
It's obviously a security-focused operating system versus some of the other operating systems that lay you down in the terminal as root. In Red Hat Enterprise Linux 9, you can't even root. It's disabled by default now. Overall, they are definitely more security conscious, and that's also because of their primary customer space.
For how long have I used the solution?
I've been using it for ten years or so. I've been using the solution since version 6.
What do I think about the stability of the solution?
The stability of what we have deployed is good. The only time it crashes is if we do something or we try to configure a control that one of the engineers doesn't fully understand, which then breaks it. A lot of it's just like us breaking it ourselves or a customer asking for something that wasn't initially planned. Just pure deployment is good.
What do I think about the scalability of the solution?
Its scalability is good. It's what they excel at. If we have 10 machines or 100 machines, they have the platforms to scale that up.
How are customer service and support?
Overall, the customer support is good. It's better than Microsoft support. They are above and beyond that. They are better than others in terms of response time, getting somebody who knows what they're talking about, and not spinning their wheel. Usually, within the first response or two, people figure out what we're trying to troubleshoot here. We're not going from one queue to another queue or anything like that.
I'd rate them a ten out of ten. I've never had an issue with it.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
We had CentOS systems. When they changed upstream, we had to pivot some systems. We pivot some systems to Oracle Enterprise Linux, but then those eventually got transitioned to Red Hat as well.
The main reason for the switch to Red Hat was for the government customer and having a support contract. You can do Oracle Enterprise Linux without a support contract, but if you're going to buy one, you might as well get Red Hat at that point for the added benefits.
We use Kali for a couple of other use cases, and we probably won't replace it with Red Hat.
We've used a lot of flavors of Linux. One thing that sticks out for me, even in just the home lab environment or deploying at work, is that if there's some backward thing that we weren't planning on going into, if I look for a solution, nine out of ten times, I'm going to find an article on Red Hat's website where somebody has either a verified solution or somebody is talking about it and there are comments that are relevant. I hate going on ServerStack, Ubuntu Stack, or something like that, where somebody has the exact problem that you have, but there are no comments and no answers. I find that to be less true with the Red Hat platform.
How was the initial setup?
The initial setup is pretty straightforward but can be tedious at times because of the compliance things that we have to implement.
I just sat in on the training or the demo for the deployment platform, and we're already planning on setting up the Ansible automation platform where we also want to look into setting up this deployment tool because we do a lot of ISOs. We do a lot of kickstarts. We don't do any of the cloud tenants. We probably will switch to using the on-premise disconnected deployment capability because we can preconfigure everything and then run Ansible after the fact to get it all compliant.
What about the implementation team?
We're the integrators or implementors of the solution.
What was our ROI?
We're forced to buy the licensing, but it's also good. I and a couple of other staff members are all Red Hat certified engineers, and then we all have our own specialties, so we don't call them a lot, but when we submit tickets, it's definitely worth it.
The ROI is mainly in terms of needing to recover from any system downtime. If we don't have an engineer on a computer doing a certain piece of research, then we're wasting money or just not generating a product, so to have the support that we can call and then reach out to us in enough turnaround time holds value for us.
What's my experience with pricing, setup cost, and licensing?
The pricing is fair. The workstation licensing cost is fair. If you're running enterprise-level deployments, depending on what you're using, the volume licensing is good. I personally am worried that if they get so successful, they can increase the price, and then it won't matter because we'll be stuck on them. Hopefully, their open source mentality keeps that from happening. Where it's right now is good.
What other advice do I have?
In terms of the portability of applications and containers built on Red Hat Enterprise Linux, I don't know how much that applies to us. In our case, someone develops an application in a Podman container, and we ingest that and run it, but we're not doing much more than that. So, all of the Java-based applications that we run, are run within a couple of different containers, and that's about it.
I personally use Red Hat Insights in my home lab. We can't dial out for that for a lot of customer-based work, but I personally use it. It hasn't helped avoid any emergencies because it's super low risk for what I'm using it for, but I can see the benefit of it. In a more enterprise setup, such as health care where I used to work, things probably would have been interconnected, and we would have been using Insights, but we're not using it currently.
Overall, I'd rate Red Hat Enterprise Linux a 10 out of 10.
Which deployment model are you using for this solution?
On-premises
Improves uptime, and it's very stable, scalable, and secure
What is our primary use case?
We are running our critical applications on it. We are using versions 7, 8, and 9, and we are running our workload on private clouds. We are currently testing Azure, but we don't have the production workload on it.
How has it helped my organization?
By implementing Red Hat Enterprise Linux, we wanted to solve some of the reboot problems of Windows. Every patch on Windows affected our applications because the system had to be rebooted. Red Hat Enterprise Linux has improved the uptime of the applications.
For our company, Red Hat Enterprise Linux is a very secure operating system. It's much better than the Windows system. It's great for us. SELinux is a great tool to protect us from attackers. SELinux is the most important for us.
We have been Agile for two years, and Red Hat Enterprise Linux has been a part of it.
What is most valuable?
Its stability is most valuable. I'm a technical guy, and I love Linux. For me, it's the best platform.
What needs improvement?
Writing SELinux policies is sometimes very hard if you want to deploy a new application on it.
For how long have I used the solution?
I started working in 2006, and my first job was administering the Red Hat Enterprise Linux system.
What do I think about the stability of the solution?
What do I think about the scalability of the solution?
Its scalability is extremely good. You can scale it everywhere if you want. We have 600 to 700 Red Hat Enterprise Linux systems.
How are customer service and support?
The support from Red Hat is very good. The response time is rather low. We have premium support, and we sometimes get an answer to our questions in one hour. If you explain to the support guy your problem, you will get the current answer. Overall, I'd rate them a nine out of ten because you sometimes get someone who doesn't understand your question.
I don't know about the knowledge base of Red Hat Enterprise Linux, but I know the knowledge base of OpenShift is very good now. In the past, it was updated in one single version, whereas now, the change is there for each major and minor version. There is separate documentation, and that's much better than in the past.
How would you rate customer service and support?
How was the initial setup?
It's getting better and better. In the past, versions 3 and 4 were very complex, but now, it's very easy to do it. We are now creating images and deploying it on our VMware farms, and it's much easier than making a PXE boot from our bare metal systems.
Which other solutions did I evaluate?
We evaluated other solutions. We went for Red Hat Enterprise Linux because of better handling. It might also have been cheaper, but I'm not sure. My company decided to go with Red Hat.
What other advice do I have?
As an operating system, I would rate Red Hat Enterprise Linux a ten out of ten.
Robust, provides good control, and has great a knowledge base and support
What is our primary use case?
As a whole, our organization is using it on Bare Metal on-prem and the private cloud, and then also in more than one public cloud environment. We probably have all three cloud providers. We definitely have Azure and Google Cloud. The environment that I support has about 40 apps in one cloud or another, but the organization as a whole definitely has hundreds of apps in Google Cloud or Azure. They're predominantly in Azure. The Google Cloud adoption is pretty recent compared to our Azure utilization.
I'm supporting a capital markets environment. A substantial portion of my environment is still Bare Metal at Colos. I'm sure on the application side, there's plenty of JBoss in our environment. There have been recent conversations around OpenShift on-prem that I'm working on, and our enterprise cloud teams are looking at or are using ARO in the cloud. In the next year, our use of the Ansible Platform will go from zero to full throttle as quickly as we can make that happen. We found the event-driven Ansible very interesting.
How has it helped my organization?
They've helped us work on employing technologies suitable to our various use cases. We're pretty slow adapters of containers, but that seems to be changing fairly quickly at the moment. That certainly gives us portability for workloads. They helped us with some aspects there, and they've helped us with a lot of automation conversation at the summit this week as well around Ansible.
When it comes to resilience in terms of disaster recovery, the operating system is robust. If it fails, it's probably an app issue. The majority of work in any of our DR scenarios is dependent on whether we have got cold standby or hot standby. If it's hot, the data replication is already there, and things are already spinning. Maybe it's on or you turn it on. Other times, you may have to start up something. Nearly all of those things are application architecture decisions as opposed to dependencies or things from an OS perspective, but in terms of the ecosystem for managing our Linux environment, using Satellite and so on has been very good.
What is most valuable?
I prefer it to Windows because of the level of configuration, level of control, and the ability to see the performance of processes on a given system. I prefer the control over logging and the ability that logging gives you to investigate a problem.
Its community is also valuable. It's open source, and Red Hat-supported streams are also valuable.
The level of communication we've got with them is fantastic.
What needs improvement?
The integration with the apps and support could be better.
A colleague was talking about having some recommendations for the Ansible Cloud on the console and having some way of identifying your dev or prod path and whether you've got read or execute access to a playbook. There were different things like that, and they made a lot of sense, especially if you're in a dev or prod environment because mistakenly running something in prod would be a huge issue. There could be something that Red Hat configures, or there could be a text field where organizations can add labels to a part of the console to distinguish that for themselves. Those would be things that would be useful. I can't imagine it's hard to implement but being able to know which environment you're in matters a ton.
For how long have I used the solution?
As a part of my professional career, I've been using it since 2004. I joined my current organization in 2018. It has been almost five years since I've been working with Red Hat Enterprise Linux in the security environment of our organization.
What do I think about the stability of the solution?
It's stable. We rarely have our systems crashing.
What do I think about the scalability of the solution?
It's pretty easy and getting easier. It's not an OS issue. In terms of scalability, even while running our trading apps, we don't run into limitations related to the OS. Our limitations are more hardware-defined, and even then, we're running Red Hat Enterprise Linux on servers with eighty cores and almost a terabyte of RAM, and the OS doesn't have any issues.
How are customer service and support?
Their knowledge base is great. There are lots of times when we don't even have to open a support case because we find what we're looking for.
I've spent a lot of time with the Red Hat account team over the past nine months. They've helped me understand products. They've helped develop the skills of my team. They've helped us with technology conversations with other parts of my organization. They've been hugely supportive of the technology conversation we're having with other parts of the bank.
They've been over and above the expectations in most cases. I'd rate them a ten out of ten. I don't know if it could be better. It has been extremely good. They've been extremely helpful in reaching out and figuring out what they can contribute. The account manager that they have working with us is a former colleague, so it's a really smart decision because we have a very good relationship with the guy. He knows our environment. It has been extremely positive.
It's a growing relationship with Red Hat. We have been using Red Hat Enterprise Linux for a very long time, and I don't know if we can even compare it to the other OS vendors, but having the account team working with us with that level of experience with our environment helps them work with us. It helps us accomplish what we're trying to do. It has been a very good partnership.
How would you rate customer service and support?
What's my experience with pricing, setup cost, and licensing?
We get our licenses directly through Red Hat.
What other advice do I have?
We haven't used the image builder tool or insights, but it's something that we might explore in the coming months.
I'd rate it a ten out of ten. It's very customizable and very supportive. It never seems to crash. There could be better integration with apps, but from an OS perspective, it's excellent.
Great support, predictable, and does what I need
What is our primary use case?
It's pretty much everything that we have. We don't have a lot of Windows in our environment.
I've been using it a lot for several years. In the past, I ran a small web hosting company, and we used it for web servers, mail servers, FTP servers, and other things like that. After that, I was in casinos, and those were mostly Windows, but here, it's a lot of Linux, and it's all Red Hat. In my team, we just build it and make sure it keeps running, and the application teams do what they do.
We use Red Hat Enterprise Linux on-premises. We support the in-house server-based things, and we have another team that supports all the cloud-based things, so I don't have a lot of visibility into the cloud.
In terms of the version, we're trying to phase out version 7. We just brought in version 8. Our Satellite is a little bit behind. By the time that gets caught up, our version 8 should be a little bit more solid, and then they can start testing version 9.
How has it helped my organization?
I haven't been on this team for a very long time. I've only been on this team for a couple of years, and it was already in place. In the past, we used it to get the stability and the support that we needed because, for a web hosting company, it was either IIS or Apache, and that was back in the NT days, so obviously, we went with Apache. I find it a better server operating system, so that's what we use.
I don't use it in a hybrid cloud environment, but my organization does. I like its built-in security features when it comes to simplifying risk reduction and maintaining compliance. All the firewall features and iptables have been fine for me. SELinux has been great for me. With the hosting that we used to do, SELinux was great because we had to share files with customers. It made it easy to make sure that files stayed secure and only changed by whoever needed to touch them.
What is most valuable?
I just use it. I'm strictly into command lines, and they just do what I need them to do, and I know how to use them. Everything is just stable and works well.
What needs improvement?
It works fine for me, and it does what I need already. It does everything I needed to do, and it has for so many years. The only change that stumped me was the networking in version 9. I preferred the ifconfig way of doing things, but the system changes of it have grown on me. I preferred the ifconfig way because of familiarity. I knew how to manipulate things. I knew how to get things running and stay running and script ways to keep them running and notify me if the thing went wrong. My only gripe has been the networking change and the inability to use ifconfig anymore. I talked to some people, and they did point out that it's good if you're moving from one environment to another environment—like a laptop, but for servers, I don't need that. I just put my config file where I can find it and make the changes that I need.
For how long have I used the solution?
I've been in this organization for a couple of years, but I've been using Red Hat since version 3. It has been a long time.
What do I think about the stability of the solution?
The stability has been pretty great. There are some things that we're still working on, but once we solve them, I know they'll remain solved.
What do I think about the scalability of the solution?
Scalability has been great too because when we need more, we just add more, and we're good.
How are customer service and support?
They've been great. I've worked with them a lot lately. They've been a ten out of ten. They're always there for us, and they answer us quickly.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
I've personally used everything from Slackware to OpenBSD, FreeBSD, Red Hat, Fedora, and Ubuntu. I've used everything.
I like the way that everything is predictable with Red Hat Enterprise Linux. You know what you're getting. You know where everything is, and you know that you can find support if you need it. When we're upgrading or if we're adding something, I always know where I could find what I need to find.
What was our ROI?
I would think that we have seen an ROI. Our licensing has been very fair, but I don't have a lot of visibility into that.
What's my experience with pricing, setup cost, and licensing?
I like my developer account. The free sixteen licenses that they give with the developer account are great because that gives me the ability to keep using it at home instead of trying CentOS or something like that. Once CentOS went away or changed, I had the ability to just make a developer account and spin up my entire lab in Red Hat, which made it better anyway because that's what we use at work, and now I have a one-to-one instead of a clone-to-one.
What other advice do I have?
I've been trying to find a reason to use containers, but I just can't. I know our company uses it a lot, and they love it. They love the ability to shift things around and bring down servers when they want, and all of that, but for my own use cases, I haven't had a reason.
Overall, I'd rate Red Hat Enterprise Linux a ten out of ten. Everything is great.
