Red Hat Enterprise Linux (RHEL) Reviews

Our primary use case is that we use it for transaction servers.

We have it on-premises, mostly virtualized.

RHEL helps speed up our deployments. We don't use things like Kickstart and Satellite for deployments, because we usually just clone systems. But the ability to script customizations during deployments is particularly useful for us. It enables us to tailor each machine the way it needs to be.

We use RHEL to run multiple versions of the same application or database on a specific operating system and its features for managing them, things like Satellite and Insights, make management of multiple versions of an application server much simpler.

We use Red Hat Insights to monitor the systems and it is a godsend. It's like having an extra person on staff. Insights is a constantly updated database of CVEs and configuration best practices. It checks everything in the environment to make sure that it is patched, up-to-date, configured properly, and using industry best practices. When you look at the Insights control panel, you know either that everything is good or, if you have an issue, you know exactly where to look and how to fix it. Nine times out of ten, it even gives you an automation script to fix it automatically.

Other than Satellite, we also use Red Hat Ansible, but not Ansible Tower. They integrate very well with RHEL. They're tooled for integrating with it and they do that well. That integrated approach makes my life much easier. The primary function we use Satellite for is patching. Having something that's built to manage application environments and make sure that everything is patched correctly to use Ansible, plugs into everything else, including Satellite. You can use it to manage RHEL, Satellite, and other things, such as Windows and networking equipment. The tightest integration is with Red Hat.

RHEL enables us to deploy applications and emerging workloads across bare-metal and virtualized environments and I find those workloads to be extremely reliable. The reliability is so good that I rarely find myself calling Red Hat support any longer. Support is the first benefit of using RHEL, but the second thing is that the platform is so stable that the need to use support is negligible.

There is potential for improvement when it comes to ease of use. It has become easier to use over the years but could be better still. Linux, in general, has never been a simple solution. It's usually a more complex solution than something like Windows. If there is a downside, it's that it is more complex than some of the other solutions.

I've been using Red Hat Enterprise Linux (RHEL) for about 10 years.

One of its most valuable features is its stability and reliability.

We have applications that we've scaled quite significantly, with over a dozen servers running the same application, load-balanced, and RHEL scales quite well.

We have an installation of about 200 servers and about another 800 servers in our SaaS environment. We're looking to grow the environment where it makes sense. I like to take the approach of considering the appropriate tool for the job. We are primarily a Windows shop, but often the right tool for the job is Red Hat. That's where we would grow our environment, where it's appropriate and the right tool for the job.

Our engagements with RHEL support are usually good. It's been a while since I've had to contact them, but they're good even when it's a significant issue that takes time. They don't even have any problems moving issues around through time zones and having support work on them around the world.

Positive

The initial setup of RHEL is very straightforward. It's all menu-driven and most of the time there are only a few answers that need to be given during the setup procedure to get a system up and fully running in a few minutes.

We can get a system up and running in about 15 or 20 minutes if we need to. We can do a custom build and use the full build process, or sometimes we do virtual cloning and then just run scripts to individualize the machines.

RHEL's single subscription and install repository for all types of systems may be a bit of a stumbling point. It seems that the descriptions of the subscriptions change every year or two and it gets a little complicated. And the naming conventions they use in the subscriptions can be a little complicated.

As for maintenance and administration of RHEL, there are just two people in our organization who handle that, me and another engineer.

The prices are comparable, and good for what is being provided.

RHEL is certainly more difficult to use than Windows, but it requires fewer hardware resources than Windows and, in my experience, it has also been more robust.

The fact that RHEL is an open-source solution isn't a concern, directly. Where it might be a factor would be when we're looking at using a tool for a particular need and we're looking for the best platform for it. That's the biggest factor.

Make sure that you have well-trained engineers who are familiar with RHEL. If you are looking for a solution that runs in a mission-critical environment, you always want a supported solution. If you're looking for Linux, I don't think that there's a better-supported solution than RHEL.

In our particular scenario, our underlying infrastructure is either VMware virtualized or bare metal, although the latter was mostly in the past. Rolling out to a virtualized solution or rolling out to bare metal with RHEL—with the exception of the bits that are unique to those platforms—the operating system installation and the like are going to be very similar.

Overall, RHEL is a very solid solution.

My primary use case for Red Hat Enterprise Linux is for cloud-related tasks, such as working on AWS. Specifically, I create virtual servers on Amazon EC2 instances. My department has 50 people using the solution.

Red Hat Enterprise Linux has increased our productivity by making monitoring more manageable and allowing us to be more proactive. We get more information we need from the virtual machines using the command line. It's also a highly secured system with built-in protections. We've also saved time because command-line operations are more efficient. Time is money, so we also save money by decreasing our time on these tasks. 

When I started working with Red Hat Enterprise Linux in March 2021, I did not immediately realize its benefits. It took me several months to understand the full power of Red Hat Enterprise Linux and the problems it solves. After three to six months, I recognized the full power of Red Hat Enterprise Linux. 

The most valuable feature of Red Hat Enterprise Linux is its command-line capabilities, which allow you to execute large operations quickly. For example, let's say you want to create a hundred files or directories. In Windows, you need to create each one by hand, which is difficult and time-consuming. Linux has multiple commands to create files in a few seconds. It also has the "top" command that gives you all the processes running and their utilization of resources like CPU, RAM, etc. That isn't possible with a management console or GUI.

Red Hat Enterprise Linux has good security features, so it's harder to breach than Windows. There's also a large Red Hat Enterprise Linux user community, so when I get stuck, I can go to Stack Overflow or other user forums and get help. I typically get a solution within a few hours when I post a question. 

I don't handle patching and provisioning because I don't have much experience, but I've heard from senior engineers that it's easy on Red Hat Enterprise Linux. 

Red Hat Enterprise Linux could make some back-end improvements. On the front end, Red Hat Enterprise Linux could make the interface more colorful and improve the user experience. A better-looking interface would attract more customers.

I have been using Red Hat Enterprise Linux since March 2021.

Red Hat Enterprise Linux is stable, providing a reliable platform for our operations.

I would rate the scalability of Red Hat Enterprise Linux as nine out of ten, indicating it scales well with our needs.

I rate Red Hat support eight out of 10. The technical support is excellent. They are readily available to assist with any technical issues that arise. Their documentation is clear and built into the GUI, so you can easily access information if you're curious about a topic. Red Hat has a large, well-informed user community.

Positive

Previously, I used only Windows, but now I use Windows, Linux, and AWS environments. I transitioned to Red Hat Enterprise Linux as it enhances productivity, reducing the time-consuming aspects of software development and project management.

Setting up Red Hat Enterprise Linux wasn't complex, but also not overly simple. It was about average. It took about half an hour to deploy the solution at one location. After deployment, we need to install updates, but that process has gone pretty smoothly.

We have a team of more than twelve individuals working with Red Hat Enterprise Linux.

Red Hat Enterprise Linux has saved us time and increased productivity. We've also saved money by not purchasing other operating systems, such as Windows or Mac. 

Most Indians will find Red Hat Enterprise Linux a little costly. It's slightly above average. Its pricing has room for improvement because it's more expensive in the local market due to purchasing power parity in India. 

I highly recommend Red Hat Enterprise Linux to others due to its productivity benefits and efficient command-line operations. It offers key advantages in terms of time-saving, security, and community support.

Our containerized workloads utilize Docker and Kubernetes and run on Red Hat Enterprise Linux to support Final Shell operations.

Red Hat Enterprise Linux helps to partially centralize our development.

The primary advantage of using Red Hat Enterprise Linux for containerized workloads is the robust support it offers in case of any issues.

Red Hat Enterprise Linux has worked well for our business critical applications.

The built-in security features are great.

One of the most significant advantages is having Red Hat behind us. If we encounter problems, we can always call them for assistance, so we are not alone with our problems.

Red Hat Enterprise Linux helps reduce our TCO.

The support from Red Hat is valuable. Having Red Hat behind us provides reassurance, and they deny unauthorized applications the ability to perform actions they shouldn't.

Red Hat Enterprise Linux's SELinux can be challenging to manage and troubleshoot, often causing frustration. While we've resolved these issues, improvements to SELinux would be greatly appreciated. Though not yet explored, Red Hat Insights could potentially aid in resolving broader Linux problems.

I have been using the Red Hat Enterprise Linux for about ten years.

We have yet to encounter problems related to Red Hat.

We install a new server if needed, and it works seamlessly.

Red Hat provides proactive support, including monthly check-ins and arranging calls to address any issues that may arise.

Positive

We do not have any other realistic options besides Red Hat.

The greatest return on investment lies in the platform's user-friendliness. Red Hat seamlessly manages all aspects of versioning and security, eliminating the need for my intervention.

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

If your budget allows, I recommend testing Red Hat Enterprise Linux. It's quite easy to install, with Red Hat providing a comprehensive setup that eliminates configuration concerns.

We use Red Hat Enterprise Linux for Ansible, network monitoring systems, and similar applications.

We implemented Red Hat Enterprise Linux because it is widely used in our region and offers excellent support.

Red Hat Enterprise Linux has enabled partial centralization of our development processes.

It performs well for our business-critical applications and has robust built-in security features.

Red Hat Enterprise Linux has contributed to business continuity and compliance efforts.

The built-in security features are quite good.

Red Hat Enterprise Linux has ongoing potential for improved integration with hosting solutions and VPNs as the demand for these technologies grows.

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

The support has a good community. It's easy to find almost every resource needed.

Positive

The biggest return on investment when using Red Hat Enterprise Linux is that it's Linux. I've lived so long with Red Hat Linux, so it has always had a good history.

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

When considering a third-party Linux OS, Red Hat Enterprise Linux is a strong option due to its excellent support and robust ecosystem.

Our primary use case for Red Hat Enterprise Linux is to set up and manage servers for various application teams, especially those dealing with hospital ADT applications. These applications handle critical data related to patient admissions and management within healthcare facilities. 

While configuring Red Hat Enterprise Linux and its associated tools can be complex and sometimes frustrating, I have found that leveraging the support and resources provided by Red Hat is invaluable. Through collaboration with Red Hat's support team and a better understanding of the intricacies involved, we have significantly improved the speed and efficiency of managing our extensive infrastructure, making the process smoother and more manageable than before.

Red Hat Enterprise Linux has improved our system's security. 

While measuring uptime is important, what matters most to us is improving the value and efficiency of patch and reboot cycles. Red Hat Enterprise Linux's tools, including Satellite and Ansible, provide valuable visibility and transparency regarding vulnerabilities, packages, and infected systems, helping enhance security and patch management.

The most valuable feature of Red Hat Enterprise Linux is the Ansible Automation Platform, closely followed by Satellite. These two tools are integral to our environment. 

Satellite helps with provisioning, managing metadata, and licensing, while Ansible ensures uniform setup across our extensive environment, making the management of our infrastructure much smoother and more efficient.

Red Hat Enterprise Linux could be improved in several ways, especially regarding transparency and communication of new features. Enhancements could include better documentation and quick reference materials for various user groups, including developers, system administrators, etc. 

Additionally, there could be improved visibility for new and improved commands within Red Hat Enterprise Linux. Many users still rely on outdated commands when newer, more efficient alternatives are available. Providing frequent updates and maintenance for resources like the admin blog would help improve communication and transparency regarding Red Hat Enterprise Linux's capabilities and features.

I have been using Red Hat Enterprise Linux for 11 years.

I would rate the support for Red Hat Enterprise Linux an eight out of ten. There has been a noticeable improvement in their support, particularly after their acquisition by IBM.

Positive

The deployment of Red Hat Enterprise Linux was initially complex because we were not aware of all the available tools to streamline the process. We had to learn, but now we are more proficient. 

Tasks that once took a month can now be completed in a week. We worked directly with Red Hat Enterprise Linux, without an integrated reseller or consultant.

We have seen a return on investment with Red Hat Enterprise Linux. By transitioning applications to the Red Hat Linux platform, we have been able to reduce our data center footprint and associated costs, such as electricity. This cost savings in other areas has been a clear benefit of using Red Hat Enterprise Linux.

Our upgrade and migration plans are focused on a balance between stability and staying current with the latest and most secure versions of Red Hat. 

While there is a desire to be on the cutting edge, we must consider what is currently in use by our clinicians and staff who rely on our hospital systems. We aim to strike a balance between these factors and leverage a sandbox environment to test the latest versions before deploying them in our production environment. 

We have been thoroughly impressed with Red Hat Insights and are currently in the process of exploring Leapp, which has shown great results in our evaluations. The web console has been invaluable for us, particularly when collaborating with application custodians who may not be familiar with the command line interface. 

We use Ansible for managing our Red Hat Enterprise Linux systems for provisioning and patching, which has improved visibility and reduced issues compared to third-party solutions. Overall, I would rate Red Hat Enterprise Linux as a nine out of ten.

We use Red Hat Enterprise Linux for virtualization and multi-cloud environment integrations.

Red Hat Enterprise Linux has improved our organization by at least 10% in the business unit and multiplies across the other business units as well.

The most valuable features of Red Hat Enterprise Linux are the mobile applications and getting real-time notifications. With other solutions, each cloud infrastructure is hard to manage with different notifications coming on, but Red Hat Enterprise Linux is able to go on-premises and cloud.

A lot of improvement is required to get security compliance, especially with the privacy of the data, managing it, and storing it.

I have been using Red Hat Enterprise Linux for five to seven years.

The solution's initial setup involves initial hiccups going back and forth to the requirements and the architecture, but so far, so good.

We have seen a return on investment with Red Hat Enterprise Linux regarding timely customer delivery, leading with innovation, and going into cloud solutions. It has progressed, and the maturity level has improved. So, we are learning as we go along this journey.

A lot of improvement is required to get security compliance, especially with the privacy of the data, managing it, and storing it. I'm sure Red Hat Enterprise Linux will be able to improve in the future.

Red Hat Enterprise Linux's effect on our system's uptime or security has been really positive. Especially with the customer's feedback coming out, I would definitely like to continue its usage.

It has enabled us to achieve 50% security standards certification. It doesn't fall into that domain, but the overall security policies do help integrate with it.

We use Red Hat Enterprise Linux in a hybrid-cloud environment. It has not yet supported our hybrid cloud strategy. It's still a work in progress, but I'm sure they will be able to do it in the future.

The knowledge base offered by Red Hat Enterprise Linux is really helpful, especially in connecting different cross-functional communities.

Our in-house monitoring services team with the network operating center manages our Red Hat Enterprise Linux systems regarding provisioning and patching. It has quite a good integration with Red Hat.

We have tried Red Hat Insights, and it's really helpful for the market competitive intelligence portal we have in-house and how it interacts with external parties.

We have tried Red Hat Enterprise Linux system roles, and it is helpful for on-time delivery.

We have tried the Red Hat Enterprise Linux web console. It has helped us 50%, and it still needs to be reviewed in more detail.

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

We are a telecommunications operator using Red Hat Enterprise Linux for our technical applications due to its supportability and robust management features.

Red Hat Enterprise Linux's built-in security features aid in simplifying risk reduction. In the past, patches fortified the security features, but now, with playbooks, we can automate and address any findings for any Common Platform Enumeration. When integrated with Red Hat Insights, the solution can identify the CPE and provide the remediation playbook. This expedites detection, remediation, and testing by Red Hat, thanks to the playbooks provided by satellite as well as malware detection.

Maintaining compliance with Red Hat Enterprise Linux is easy because it supports various out-of-the-box compliance policies, such as CIS. Whether we are running OpenSCAP on-premises or Insights, we can perform compliance testing using OpenSCAP to verify adherence to the Red Hat Enterprise Linux security guidelines, as well as other well-known guidelines and framework compliance. I have found that all the compliance policies I required were already included out of the box.

Red Hat Enterprise Linux is ready to help keep our organization agile when it comes to the portability of applications and containers because all the applications are developed by the vendor. Red Hat Enterprise Linux is the preferred choice in our industry because the applications we use are swiftly certified by the vendor, so we don't have to verify them ourselves.

Red Hat Enterprise Linux provides enhanced security for our servers, and we are aware of patching requirements in advance. Additionally, the pre-certification of Red Hat Enterprise Linux applications expedites deployment as we no longer need to go through the certification process ourselves. Moreover, Red Hat Enterprise Linux offers excellent support, ensuring that any issues that may arise are promptly addressed, which is crucial for our environment where we must maintain an uptime of 99.99999 percent.

Red Hat Enterprise Linux enables us to achieve security standards certification because it is driven by various compliance policies that include everything we need out of the box. This makes it easy to enforce security rules, and security patches are applied regularly. With Insights, we have malware detection, CPE filings, and remediation capabilities. In addition to the reactive approach, we also benefit from a proactive approach, allowing us to stay informed about the events around us, which helps us implement temporary solutions if needed until a permanent fix becomes available.

With Red Hat Enterprise Linux, we can build with confidence, knowing that it is available across physical, virtual, and cloud infrastructures. The operating system provides certifications, ensuring that we can deploy with 100 percent certainty, knowing that the applications will work. Additionally, it offers identity security and excellent support from the Red Hat team. Without this support, we would have to rely on searching within the community and downloading untested patches, which may function in small environments but not for larger ones with sensitive applications.

Red Hat Insights helps us prevent emerging issues related to security or noncompliance settings. One of the steps we take before going live is using OpenSCAP to ensure compliance with our standards. This is followed by our own security scanning and verification process. If any issues are not known within Red Hat, we can always refer to all the findings. Once the system is in production, regular monitoring allows us to use Insights to identify any new findings and apply necessary patches or workarounds. The knowledge base available on the servers enables us to take proactive measures even before a security patch becomes available. The new malware detection feature in Insights helps protect end-user information.

Insights provide vulnerability alerts and specific guidance. With each system, we can view the detected Common Platform Enumeration and receive advice on how to address it. These features have protected our systems from potential attacks, thereby increasing our uptime.

Red Hat has introduced a fast server, where Red Hat Enterprise Linux can be integrated or connected to via a client. This connection allows us to identify numerous vulnerabilities in malware easily and facilitates simpler patching. Activating the Red Hat addons on this server creates a perfect match when seeking a well-hardened OS using the gold image, as it eliminates the need to address issues from an existing image. Additionally, Red Hat Insights is a valuable and essential tool. In the telecom industry, we rely on basic products that necessitate an OS with robust security support and regular patches. 

We have not succeeded in creating an image from Red Hat Insights for Red Hat Enterprise Linux, including custom partitioning and custom scripts. This would have been helpful.

Red Hat Insights reporting can be enhanced by incorporating performance components, making it a central tool for vulnerability assessment, compliance monitoring, and much more. The performance component is available on Red Hat Enterprise Linux, but we need to maintain the dashboard on-premises, which requires us to switch between systems instead of performing all tasks from a single location.

Managing the destination for netting on the Netserver using Red Hat Enterprise Linux could be made more user-friendly.

I would like to have enhancements in the data files to help with deployments.

I have been using Red Hat Enterprise Linux for over ten years. I started in 2012 using version five.

Red Hat Enterprise Linux is stable.

Red Hat Enterprise Linux is scalable, but the scalability is achieved at a different layer compared to adding memory to a virtual machine or container.

Compared to other support departments for Red Hat products, the Red Hat Enterprise Linux support team stands out as one of the fastest, most cooperative, and understanding teams.

Positive

The initial setup is straightforward. In the past, it was complex when Red Hat acquired Ansible because many of the modules were community resources that lacked full support. As a result, creating a playbook to deploy the OS was a painful process, as there was a chance it would not work, and we would not have the necessary support. However, currently, deploying Red Hat Enterprise Linux is easy. We have never deployed only one operating system at a time, but it would take less than one hour to do so.

I would rate Red Hat Enterprise Linux an eight out of ten due to the complexity of its network boost management issue.

We have Red Hat Enterprise Linux deployed in one location.

Red Hat Enterprise Linux is used in our environment to run the application for all of our customers, and only around ten people have access to it.

Red Hat Enterprise Linux requires maintenance for applying new patches, releases, and debugging. 

We use a combination of Red Hat and Oracle Linux in different parts of the organization. We have a cluster, where RHEL is running. The instances are both virtualized and real, depending on which part of the cluster you're utilizing. They are set up as either RAC or single instance, depending on what we are trying to achieve in terms of performance.

We have PeopleSoft systems that are all deployed on Red Hat. We also use it for deploying simple websites. PostgreSQL is running on the systems, along with a frontend that was created by the developers. We also use it for DNS fallback authentication.

We have quite a few Windows systems, as well, and some of the applications that we used to run on Linux have now been migrated to Windows.

We have a mixed environment, although, in the cluster, our deployment is primarily on-premises. There are some deployments into different cloud providers, depending on the service that we're looking for. However, when we head into the cloud, we tend to go to Product as a Service rather than Infrastructure as a Service or the like. This means that we're less concerned about the underlying operating system and we try to avoid interacting with it as much as possible. So, it is just virtualization in this case.

We rely on RHEL for stability, control, and reliable updates. There may be other Linux variants that work as well or better but we're quite happy with this solution.

We try very hard to ensure that everything is working irrespective of what it's running on, in terms of the operating system and middleware, including what database is running. RHEL helps maintain consistency of application and user experience, regardless of the underlying infrastructure, simply by not being part of the problem.

RHEL enables us to deploy applications across bare metal servers and virtualized environments, and it's an area where everything seems to be working okay. It is reliable and there is nothing that is causing us grief at the moment. The only ones causing us trouble are the applications that we're customizing, although that is nothing at the operating system level.

You can set up the security services quite quickly, which we found very useful in our context because we're a highly public organization and we need to ensure that we've got things patched as quickly as possible.

This is a very robust product that doesn't require a lot of handling. It just works. It doesn't really matter whether we've got Apache components on it or anything else. It'll run.

We have used RHEL's monitoring tools, albeit very rarely. The last time we used this feature, we were trying to track down a problem with one of our LDAP services and we were not getting any useful response back from support for that service. Ultimately, we were able to track the issue to a particular character in a user's surname.

There is nothing to work on in terms of speed and performance.

We started using Red Hat Linux approximately 15 years ago.

Overall, the stability is very good.

The most recent stuff that's been a little bit kinky was in the release of version 8. They were looking to change things around with how the product is built, so it just took us a while before we started using it.

I think we waited until version 8.1 was out and then we were fine. It was a case of us letting that version settle a little bit, as opposed to version 6 and version 7, which we went straight to once released.

Scalability-wise, it suits the needs of our organization and we haven't tried to do anything more than that. When we had multinode, Oracle RAC systems, we had a four-node RAC, each of them had four CPUs and 64 gigs of RAM, and they were all running one database. Performance was not an issue with the database.

This is one of those systems that people can use without knowing it, in a web context. Pretty much all of our research staff and students are using it, at least to a degree, even if it's just for storage management. From their perspective, if you ask them what they're using then it's just a Windows share, but in reality, it's RHEL. There are between 30,000 and 50,000 users in this category, and the majority of them wouldn't even know it was Red Hat.

We've got a fairly straightforward Red Hat implementation but the users do a variety of jobs. Some of the work that we do is implementation integration, so there are no specific users per see. It's just about migrating data and files, depending on what we need. The people that use it in this capacity are academic staff, finance staff, libraries, IT staff, students, and researchers. It is also used by systems engineers, senior systems engineers, the senior security person, my manager, and his boss. There is also a deputy director and the director.

We're probably not going to increase our usage by any level of significance. At the same time, we're probably not going to decrease in any great rush either. We're in a phase where we're looking at what can be put into cloud systems, and we are targeting Product as a Service in that space rather than infrastructure.

Essentially, we're looking to move away from managing operating systems when we put stuff in the cloud, but we still have hundreds of servers, just in one of our locations. The majority of them have no plans to move at this stage, so our installed base is fairly stable.

Primarily, we haven't had to use technical support and I can't recall the last time we actually had to log a call with them. It's a really good situation to be in.

It's an interesting situation because we use Oracle Enterprise Linux primarily. It is really not very different from RHEL because it's just recompiled and they resend it. We use RHEL on one of our clusters, which has about 300 nodes in it and is used in research. In short, we use both Oracle Linux and Red Hat Linux, but the reality is that nothing much is different between the two of them.

We initially implemented Red Hat and we consolidated everything to Oracle Linux because it was cheaper from a support standpoint. That was when Red Hat Enterprise Linux version 4 was out. I think that version 5 had only just been released and we switched to Oracle, which is the same thing anyway.

The last time the research cluster was updated, it switched from the IRIX operating system to Red Hat on HP. They weren't necessarily going to implement Red Hat but we had to make sure that everything was licensed correctly, and that's how it came into play. Since it is not using our Oracle license, but it's already bought and paid for, we have not consolidated it. We could consolidate again but it doesn't make a lot of difference in terms of what we do on a day-to-day basis. It runs the same and it operates the same.

We were running version 7 of Red Hat on the cluster and we have versions 4, 5, 6, 7, and 8 running in the Oracle Linux space. The applications running on version 4 will only run on that version, and there are only two of those left. We have three instances of version 5, about 30 running on version 6. We are trying to reduce this number and we had more than 60 running on version 6 a few months ago. The fact that this is going down is nice.

Versions 7 and 8 are still supported, so the specific version is not a concern.

Prior to using Linux, we used Digital's TruCluster. However, after Digital was bought by HP, they discontinued the product.

The initial setup was fairly straightforward. We put in the satellite server and then ran the config on each of the nodes to tell them where it was. After that, the updates were happening and there wasn't anything else to be done.

We did not use a formal approach for our implementation and deployment. It was probably more haphazard than structured.

We implemented it in-house.

We have four people that support it, although they do not work on it full-time. For example, the person who works on it most consistently also does work in the networking and firewall space, as well as identity management. We have more support staff for Windows within our environment.

The most recent change we made is a flag that had to be set on the kernel for some of the machines. Setting the flag means that you can patch it without having to reboot. This wasn't particularly problematic, although we had to make sure that it was in place because we now have patching occurring on a monthly basis.

In general, there is not much to do in terms of maintenance. The biggest drama has come from organizing upgrades to the application side that sits on top, rather than the operating system itself.

We've had some done ROI analysis over the years and it's always interesting when you read them. When you consider the initial implementation and you couple that with what we did with Oracle, we saved about $500,000 USD on purchasing all of the different parts by going with Red Hat.

This is significant as well because we still had the same capability with the hardware.

We've had similar kinds of examples thrown at us over the years, but primarily that's when comparing HP-UX and other vendor-closed products.

The price is something that can be improved, as they are still being undercut.

We are an educational institution and as such, what we pay is less than the average company. There are no costs in addition to the standard licensing fees.

Red Hat's single subscription and install repository for all types of systems is something that we're quite interested in because it's simpler and easy to manage hundreds of virtual machines. However, from a pricing standpoint, it's part of the problem because it's what Red Hat utilizes to explain why they cost more.

The Oracle licensing of support for the same Red Hat product is cheaper, and it's cheaper to the level of significance that it makes it worthwhile. We have spoken with the salespeople at Red Hat about it, and they have said that there was nothing they could do.

It's starting to become a question mark over the patching with version eight. We might be changing, but we're unlikely to be changing from Red Hat. It's more a case of who's running our support, be it Oracle or Red Hat. However, we would need to look at the numbers next time we renew, which is not until next year.

Prior to choosing RHEL, we looked at a number of different things. We conducted a fairly large scan of product offerings and our analysis included cost, availability, and support. It took us about three months to go through the process and Red Hat was successful.

The fact that Red Hat is open-source was a consideration, but it wasn't necessarily a winning ticket at the time. We came from a closed source product that we were very happy with but when we were looking at the alternative closed source options, none of them were even close in terms of product offering. Also, they were actually more expensive. So, when looking at the open-source with support opportunity that we were presented with from Red Hat, it was very much a cheaper option that also brought with it a lot of reliability. That is why we chose it.

RHEL provides features that help to speed deployment, although we don't use their tools. We use tools from a third party.

My advice for anybody who is looking into implementing RHEL is to make sure that it is going to work for you. Ensure that it supports all of the products that you need it to support once you've actually assessed all of those things. It is a quality product, there's no doubt about that. Once you have made that assessment, I would say, "Great, go for it."

In summary, this is one of the products that works well and does what we need.

I would rate this solution a nine out of ten.
