We evaluated Microsoft Windows Server, Ubuntu Server, and Red Hat Enterprise Linux before ultimately choosing Red Hat Enterprise Linux.

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

I recommend Red Hat Enterprise Linux for its support and stability.

Red Hat Enterprise Linux is used within our organization to orchestrate a multitenant, microservice-based architecture. This supports a distributed system of predominantly web-based applications and frontends. A typical deployment involves around 60 to 70 Amazon EC2 instances working in concert.

The primary use cases involve running interconnected applications with requirements such as low latency and high availability, often achieved through redundant, multi-tenant, and load-balanced architectures. These applications may utilize read or write-optimized instances or be memory or processor-optimized, depending on their specific needs. Optimization is achieved through the processor, RAM, and connected protocols. The foundation for these applications is Red Hat Enterprise Linux.

Red Hat Enterprise Linux facilitates seamless workload migration between diverse cloud environments and data centers. In DevOps, workload portability between cloud and data centers is crucial, so we prioritize operating systems supported by multiple cloud providers and available locally. Key considerations include stability, security hardening capabilities, and the ability to obtain government or compliance organization approvals, which are incredibly stringent in sectors like banking and securities exchange. Red Hat Enterprise Linux meets these requirements by providing a secure, reliable, and consistently delivered operating system that facilitates approvals and ensures seamless workload mobility.

Regarding Red Hat Enterprise Linux provisioning and patching, both processes are generally straightforward. Patching can be completed within a few hours.

Setting up a correct pipeline ensures smooth provisioning regardless of the OS.

Implementing Red Hat Enterprise Linux has resulted in significant resource savings due to its efficient usage of minimal resources. Compared to other operating systems, Red Hat Enterprise Linux requires less RAM and CPU allocation, which translates to cost savings. Additionally, its stability and minimal downtime contribute to operational efficiency.

The Red Hat command line interface is more user-friendly than the Windows command line interface. Red Hat makes it easier to perform tasks like reviewing logs, checking network connectivity, checking DNS, and setting up a proxy. Additionally, searching for specific characters within numerous log files is simpler in a Red Hat Enterprise Linux instance compared to other operating systems.

The implementation and limitations of SELinux should be re-evaluated. Its current configuration presents numerous challenges and restricts certain functionalities, hindering the overall usability of Red Hat Enterprise Linux. Addressing these limitations would significantly enhance the operating system's flexibility and efficiency.

I've been using Red Hat Enterprise Linux for six years.

Red Hat Enterprise Linux is almost perfect in terms of stability. It works consistently with minimal downtime and very few bugs or glitches, deserving a high rating for stability.

There are no issues with scalability when it comes to Red Hat Enterprise Linux. It scales efficiently, fulfilling our needs without difficulty.

My experience contacting Red Hat technical support was positive, with knowledgeable and supportive staff, particularly during early hours. However, I found more detailed knowledge through community interactions on platforms like Stack Overflow.

Positive

Before adopting Red Hat Enterprise Linux for production applications, other Linux operating systems like Ubuntu and Windows servers were used for monitoring and testing purposes. Red Hat Enterprise Linux became the choice for critical server applications.

The initial setup of Red Hat Enterprise Linux is straightforward. Once the images and database information are available, the automation process is simple and efficient, taking only a couple of hours to complete.

Using Red Hat Enterprise Linux can yield resource savings of 200 percent to 300 percent compared to Windows Server instances. Its minimal RAM and CPU usage allows for smaller instances, resulting in significant cost reductions.

Red Hat Enterprise Linux is a more cost-effective solution than Windows Servers. Windows Servers base their cost on the number of users and have high licensing fees, while Red Hat Enterprise Linux offers free versions alongside its paid, supported versions. This makes Red Hat Enterprise Linux a good option for startups and organizations with limited budgets. While the free versions may lack direct vendor support, the availability of paid support options and the robust Red Hat Enterprise Linux ecosystem provides flexibility for growing businesses. Additionally, the presence of compatible open-source alternatives further enhances cost-effectiveness and choice. Overall, Red Hat Enterprise Linux presents a compelling advantage in terms of cost compared to other operating systems, especially for nascent organizations.

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

While Red Hat offers free license versions and CentOS provides a similar platform, the official Red Hat documentation may not be the most helpful resource. More valuable support can often be found in community-driven platforms like Stack Overflow, where users share their knowledge and experiences through questions and answers. This user-generated content often proves more practical and supportive than the official Red Hat resources.

Red Hat Enterprise Linux is deployed in a multi-region configuration with three availability zones per region. Data is replicated from region one to region two, which serves as a read-only replica. Traffic is load-balanced across all availability zones within a region, ensuring automatic failover to the remaining zones in case of an outage. Similarly, if an entire region fails, traffic is redirected to the other available region. This setup provides high availability and disaster recovery capabilities. We have a couple of thousand users in our organization.

Red Hat Enterprise Linux requires periodic updates. To manage logs, a retrieval and deletion method is necessary, which can be achieved using built-in features like cron jobs. Red Hat supports these features. Additionally, security patches should be applied as they become available.

I recommend Red Hat Enterprise Linux, particularly for enterprise implementation, due to its lightweight and secure design. Its robust community support and extensive availability of solutions in forums and unofficial resources make it preferable to other operating systems.

I use Red Hat Enterprise Linux to manage pre-configured web servers, troubleshooting issues such as "524 errors" and missing configurations in EMV files. Furthermore, I constructed an on-premises Kubernetes cluster on Red Hat Enterprise Linux 9 and configured it for ELK.

The Red Hat Enterprise Linux knowledge base is excellent. When I encountered an error, they were able to quickly identify the issue and guide me through the necessary steps to resolve it.

The Red Hat Enterprise Linux Web Console functioned properly throughout the lab courses.

Red Hat Enterprise Linux is excellent for commercial use and enterprise tools. It's best to use Red Hat for enterprises because it provides robust support available twenty-four by seven, which I have experienced.

To start working with Red Hat Linux was straightforward and user-friendly. I didn't encounter any complexities.

The most valuable feature of Red Hat Enterprise Linux is its comprehensive ecosystem. The detailed documentation eliminates the need to consult external resources, and the knowledgeable support team provides expert assistance with both technical issues and site navigation.

Improvement is needed for supporting Kubernetes clusters because it is less supported by Red Hat according to my experience. There are also some gaps in documentation which affect configuring Kubernetes clusters.

I have been using Red Hat Enterprise Linux for four to six months.

I have not faced any downtime or stability issues with Red Hat Enterprise Linux.

I have not encountered any scalability issues with Red Hat Enterprise Linux.

The technical support is excellent. They promptly addressed my concerns regarding permission issues when I contacted them.

Positive

I used CentOS for non-enterprise purposes but switched to Red Hat for enterprise applications due to its superior support and stability. However, Ubuntu is generally preferred for Kubernetes deployments.

Red Hat Enterprise Linux is nine out of ten.

Red Hat Enterprise Linux does not require maintenance.

Our mid-size organization has between 20 and 50 employees, including our DevOps team, who use Red Hat Enterprise Linux.

I recommend Red Hat Enterprise Linux due to its support and strategy.

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.

The solution is used for on-premises data centers. Multiple private data centers run workloads on VMware Cloud solutions, and Red Hat Enterprise Linux is deployed on critical systems. We use KVM virtualization technology to host various virtual machines on Red Hat Enterprise Linux that run workloads and applications.

Red Hat Enterprise Linux improved our compliance by working with third-party security providers, like CIS Enterprise Internet Security. It's a nonprofit organization that provides many security solutions and benchmarking for each operating system. CIS and Red Hat jointly developed a CIS-approved operating system. They work with various public cloud providers like App Engine, Google, and AWS to provide comprehensive CIS-approved images in Red Hat Enterprise Linux. 

The US federal government has already certified the OS for FIPS compliance. FIPS is the organization that designs cryptography algorithms for federal agencies, and they approved Red Hat Enterprise Linux. 

It takes some time to realize the benefits. Some customers cannot see a direct benefit because the licensing is a bit complex. In a huge enterprise environment, you could see an immediate effect, but a smaller or medium-sized organization may take a while to yield a return on investment.

The most significant advantage is that it is more stable and secure than other operating systems. Years ago, we worked on Windows-based systems with more challenges regarding patch management and vulnerabilities than Unix operating systems. We get more frequent patch releases from the vendor weekly, monthly, and quarterly. It also has strong security features, is OIS and FIPS certified, and has built-in Linux security configurations.

In addition to Linux's built-in security tools, it has Red Hat Enterprise Linux configuration features that provide robust security controls. We also have third-party solutions that provide more in-depth solutions for our cloud and on-premises infrastructure. We have to provide security at each layer of the OSI models. For example, on the application layer, we have to provide web solutions or application gateways, but it provides good security features for the OS layer. 

We use another Red Hat product called Ansible to automate patching tasks and infrastructure deployment. We don't have a large number of servers, so we manage patching and configuration through Ansible. For bigger deployments, they have solutions like Satellite, but we use Ansible. 

We use Image Builder to create a Golden Image for our CICD pipelines. We have a CIS-approved image that integrates their security controls for our automation tools and some of the ones specific to our organization. We added some of the controls from the Red Hat management framework that govern how an image should be created and what controls must be integrated into this base image. 

The web console is useful for people without Linux backgrounds who lack experience working with the command prompt. The web console helps them manage the system better without knowing all the commands.

Red Hat Enterprise Linux licensing is a bit complex. The solution operates on a subscription-based model, which may not provide immediate return on investment for small to medium-sized organizations. It also has a steep learning curve for employees unfamiliar with Linux, and it demands a skilled team or a dedicated service center to operate effectively.

I have used Red Hat Enterprise Linux for about four to six years.

Red Hat Enterprise Linux offers great stability and performance compared to other operating systems. It does not have issues with crashing or substantial downtime.

I rate Red Hat support seven out of 10. We have only opened one or two cases with technical support, but we've had good experiences. They respond immediately based on the SLA level. In the future, we plan to use Red Hat's OpenShift and Kubernetes solutions, so we expect to work with the support team more because we're new to those products. 

Red Hat's Knowledgebase is an excellent support resource. It stays updated about new things coming to our region and provides lots of articles about the products. It's a good starting point for troubleshooting without the need to call the support team. We use the knowledgebase to resolve issues as often as we can, but we contact support if we get stuck and can't find the solution. 

Neutral

We have physical systems running SUSE Linux and Windows, but we're gradually migrating them to Red Hat Enterprise Linux. Some systems are running Solaris, and we haven't decided whether we'll migrate to Red Hat Enterprise Linux or other operating systems.

Our operations team takes care of migrations and installations. We're primarily responsible for business impact assessments and helping the operations team do a POC to determine the effect on the application environment. We consider the licensing and give the operations team approval to do the migrations and install the new operating system. 

The team consists of two or three people. We cannot migrate directly from one system to another. We simulate everything in the POC environment and perform migrations in the development environment using our in-house tools. They will check the source machines and find out what applications are running. It will assess them and look into the destination systems. Using some replication technology, it will do a direct synchronous verification between one storage to the other.

We need some downtime to complete the migration, and most of the data is stored in SAN storage. That is called a long migration. Once the operating systems and associated patches and applications have been migrated, we have to migrate them manually for the storage side.

The subscription-based pricing can be costly, particularly for smaller deployments. The more subscriptions you have, the easier it is to see a return on investment because it helps larger organizations more. It may be considered expensive compared to other solutions like CentOS or Ubuntu, which offer some of the same features without additional costs.

I rate Red Hat Enterprise Linux eight out of 10. I recommend new users get some training on the platform because installations and migrations can be complex. Setting up clusters can be challenging for new users who don't have hands-on Linux experience without vendor assistance. 

We are using Red Hat Enterprise Linux (RHEL) primarily in the health care industry for AI modeling and edge computing. One use case involves specific monitoring in a room with equipment and hardware.

I'm keen on this product because everything works as expected. It has embedded compliance features. We expect more in version 10. The keynote mentioned embedded OpenSCAP reporting, which is something everyone wants.

Red Hat Enterprise Linux has a lot of specialized documentation. Typically, people search on the Internet and find solutions by trial and error. However, everything about Red Hat Enterprise Linux is there in the documentation. You only need to follow it correctly. 

The security features have room for improvement, especially for highly regulated industries like health care. That's why it isn't the primary OS in health care. It would be great if they added some features to address the specific challenges health care providers face. 

It isn't hard to patch, but migrating between versions is difficult. We have the the latest version, but the previous version is still working very well. It's hard to leave a working version to upgrade. I would like more AI features, but those will be added to the next version. We are in an AI age, and it's an area where we need to keep pace. 

I have been using Red Hat Enterprise Linux since version 3, starting around 2000. Currently, we use version 9.4.

The stability of Red Hat Enterprise Linux is excellent. I have nothing negative to report in this area.

Scaling Red Hat Enterprise Linux as our needs change has been good. The older versions continue to work well even as we introduce newer solutions.

I rate Red Hat support nine out of 10. They provide competent support and help resolve issues quickly. You don't need to spend a long time searching for a solution. I don't rely on them much, but it has been a big help for my colleagues.

Positive

I have been using Red Hat Enterprise Linux for many years, so it is my default choice when selecting an operating system.

I'm a technical guy, so I'm not dealing with the money side of things, but we've seen a return on investment in terms of time saved due to the good documentation and support. 

Red Hat Enterprise Linux is expensive, but I'm not paying anything because it's the company's money. However, it's priced comparably to other enterprise Linux solutions. It costs a lot because you have a large staff working on the concept and improving everything. There is an open-source developer part that is free, so you can test everything before buying it. 

I rate Red Hat Enterprise Linux eight out of 10.  I know this is a good product because I've used it for many years, and it continues to improve. The OS is great, so I continue to use it. If I'm working on a new project and given a choice between another solution and Red Hat Enterprise Linux, I would always choose Red Hat for the community, support, and documentation. 

There's a free developer version. If you are thinking about purchasing Red Hat Enterprise Linux, you can try the developer version for free. Practice using Red Hat Enterprise Linux, and you will see the difference between the other distributions and Linux. If you want the product to perform at an enterprise level, you need to learn the product. There a plenty of tools and also the Red Hat Academy.

I use Red Hat Enterprise Linux (RHEL) for its specific security features.

Red Hat Enterprise Linux has specific security checks that are beneficial. We follow its support and it helps with security verification.

The security features are the most valuable. The long-term support for weekends is also beneficial.

Risks, for example, specific to Linux, need improvements.

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

I am a database administrator, and we mostly use Red Hat Enterprise Linux to manage databases. Primarily, we use it for Postgres, as it works best on Red Hat Enterprise Linux (RHEL). It's easiest to set up and has the best documentation.

I'm aware of one customer that is thinking about it. But I'm not sure what specific projects they want to use it for. I think there's one customer who is interested in it and is trying to find a solution that might benefit from it. 

Red Hat Enterprise Linux (RHEL) contributes significantly to our business continuity and compliance efforts. The best example is uptime. Many critical businesses need to be operational twenty-four hours a day. If a database goes down for some reason, it is seldom Red Hat Enterprise Linux that is the issue. This provides peace of mind.

It has helped us centralize development because Red Hat Enterprise Linux has many tools that aren't accessible to our Windows customers. 

Red Hat Enterprise Linux's most valuable feature is its reliability. I don't have to worry about the operating system. It's one of the easiest operating systems for databases, and the integration is excellent. It gives me peace of mind because I can focus on my database work without worrying about my OS. I want to ensure I have applications that run on the OS without searching for temporary fixes or workarounds. 

It has some of the best out-of-the-box security features of any Linux distributor. Red Hat Enterprise Linux has more built-in security features than most standard flavors, or it has implemented them better. 

I haven't identified anything that needs to be proved, but I hope Red Hat Enterprise Linux maintains its reliability.

I have used Red Hat Enterprise Linux for the past five years.

Red Hat Enterprise Linux has been perfect. My Windows customers experience a lot more downtime and bugs. Our critical businesses need to be up 24/7. It's rarely its fault if a database goes down. I would estimate that there's about 10 percent less downtime compared to Windows customers. 

I haven't been involved in any real project that necessitates scaling as our needs change.

The support is excellent compared to other solutions like Oracle. They're knowledgeable and easier to work with. We have a nice, transparent working relationship. 

Positive

The biggest ROI is from Red Hat Enterprise Linux's reliability. If I run databases on Windows, I have to find other tools or workarounds. It's a big hassle. Red Hat Enterprise Linux lowers the total cost of ownership for my customers because I bill fewer hours than I would in a Windows environment. Open-source databases run better on Red Hat Enterprise Linux than on Windows. Most things I need are built-in or can be downloaded from the repo. 

Ubuntu is commonly used, and there's a decent amount of documentation for databases, but it can't compare to Red Hat Enterprise Linux. Setting up Postgres or any open-source database on Red Hat Enterprise Linux is way easier. The documentation is more extensive. It's also easier support because many customers have a subscription with Red Hat.

I rate Red Hat Enterprise Linux nine out of 10.

My advice would be to focus on reliability and ease of integration when choosing a Linux OS.
