Red Hat Enterprise Linux (RHEL) for AWS

I am currently working on dialing up telecom services that are due to telecommunication needs in Sri Lanka. We are using this for mother data center activities, not only as a solution but for multiple purposes. I am currently handling the data engineering team.

Red Hat Enterprise Linux (RHEL) , we are testing. Red Hat Enterprise Linux (RHEL)  ten point one is also there in beta. In that manner, Red Hat Enterprise Linux  (RHEL) does a couple of things. We are the partner of Red Hat Enterprise Linux  (RHEL) in our dialogue at the digital lab.

At the moment, we are using ten. Because we use it most of the time for the test bed, which is the development bed, ten is at the moment our version.

The main thing as a cloud-based solution is valuable. Beyond that, it is an on-premises solution. We are also using a stable established version called nine point two from Red Hat Enterprise Linux (RHEL). We are supposed to move to Red Hat Enterprise Linux (RHEL) as well.

Red Hat Enterprise Linux (RHEL) is paid. When it comes to the total Red Hat Enterprise Linux (RHEL) management, they are using project insight for part of the services. We will take that Red Hat Enterprise Linux (RHEL) Insight.

That is really helpful. It is a kind of dashboard, not only a dashboard. We can get decision-making capabilities going forward when it comes to security.

OpenShift gives a good solution for us on the Red Hat Enterprise Linux (RHEL) end. The session, not only the station, has the CI/CD pipeline and operators connecting. That is a really good improvement on the Red Hat Enterprise Linux (RHEL) side.

Sometimes we are lagging in the Red Hat Enterprise Linux (RHEL) part because we have to deploy in non-straightforward environments. Some environments have third party deployments where party enhancement happened.

Red Hat Enterprise Linux (RHEL) is lagging in these scenarios. The main problem we are facing is the cost factor. Because it comes to long and short terms, stakeholders do not want to move to a good business solution because of the cost factor. That is still where we are lagging.

I have been using this solution for more than industrial use, more than fifteen years, almost twenty.

I think that now, as of just now, there is no downside. It is not crashing, basically. The application is rebooting every time because of some kind of bug.

You have to master the tips and then come to Red Hat Enterprise Linux (RHEL). The knowledge base is actually lagging because most of the people do not want to work with the backend coding and Red Hat Enterprise Linux (RHEL). We are commanded to use it to upgrade anything.

Because of that knowledge gap and Red Hat Enterprise Linux (RHEL) in Manam, but people are not using much more. Even administrators are not using proper principles and guidelines to do so.

When I was in the consumer space, I realized console R is also more toward Red Hat Enterprise Linux (RHEL) kernel. Exadata and now Oracle are all moving to Red Hat Enterprise Linux (RHEL) because of the kernel quality.

It will help a lot. When it comes to big data development, we have twenty servers to deploy with all kinds of packages and modules. Then it will easily deploy using the Ansible  playbook to write the code and everything. So it is easier to deploy, actually.

It is an integrator, basically. It is cloud and cloud enablement because I had experiences when we were going to do that Cloudera migration.

That is really helpful now when it comes to the integration point of view. That is Red Hat Enterprise Linux (RHEL) too, I believe.

Then we are going to do some implementation. They are aligned with the Dell partners. Those kinds of matters come up because of the cost. This comparison comes to the picture.

When it comes to the backup solution, we are using tune the profile to utilize the backup solution. When we are using performance stack, we have tuned the performance stack to do a couple of testing in production as well. That is the main thing we are basically using most of the time.

Our engineers are supposed to do that base. Now they are implementing that base. I carry it forward to the next level, which is the business solution. When we are seeing Red Hat Enterprise Linux (RHEL) Insight, we can take the next action as much as the next action method allows. For instance, when we say we want to patch the environment, Red Hat Enterprise Linux (RHEL) we are testing. Red Hat Enterprise Linux (RHEL) ten point one is also there in beta. In that manner, Red Hat Enterprise Linux (RHEL) does a couple of things. We are the partner of Red Hat Enterprise Linux (RHEL) in our dialogue at the digital lab.

Next year, I will recommend Red Hat Enterprise Linux (RHEL) because they have a lot of features and functions, especially for the enhancements. When it comes to security, now they have a lot of features. For instance, saving us is a really good enhancement way to achieve the environment. When it comes to the use of solution, that is really interesting.

I am using Red Hat Enterprise Linux (RHEL) for almost fifteen years now. I really understand what Red Hat Enterprise Linux (RHEL) did then and what kind of solutions they provide. Accordingly, I am aligned and most of the time when I say I am going to do some kind of upgrade, I definitely use that release and knowledge, principle, and guidelines. Otherwise, we cannot do it. I have given this review a rating of ten out of ten.

I am a RHCE certified and RHCSA certified professional. I use Red Hat Enterprise Linux (RHEL)  to deploy the OS for node provisioning across any make of clusters. I work with the HPC cluster team and receive clusters on RHEL-based systems. Over the last seven years, I have been working with RHEL  7, RHEL 8, RHEL 9, and currently RHEL 10. I primarily work with HPC clusters.

Since creating HPC clusters is not part of my responsibilities, I focus mainly on installation, node provisioning, password management, SSH proxies, and NGINX  and web server configuration.

There are several valuable features I appreciate. I can obtain any versions, software, or RPM packages easily through the subscription manager or without it. Red Hat Enterprise Linux  (RHEL) is very hands-on for me and runs smoothly. It even runs on just 1 GB of RAM, which is excellent for my needs. The installation process is very easy compared to other distributions. Since I work with clusters, this simplicity is invaluable.

When comparing the installation process of Red Hat Enterprise Linux  (RHEL) to other distributions, I find that a non-technical person can easily follow the prompts. The installation guides are clear and documented step-by-step. For example, the first prompt asks for language, keyboard, and installation preferences, and each step is straightforward. In contrast, Ubuntu  and other distributions require creating disks and involve more complex UI elements that are not as user-friendly. Red Hat Enterprise Linux (RHEL) has a clean interface that allows even non-technical people to install the OS easily.

I have only studied from the direct books provided by Red Hat for RHCSA and RHCE certification, and every detail is available in their documentation and website. I appreciate the clean and detailed information provided in their resources.

I encounter pain points when trying to add patches for certain versions I need for RHEL purposes. While creating HPC clusters on RHEL 9, I sometimes need EPEL repositories for RHEL 7 or 8. Adding patches from these repositories is very painful because Red Hat Enterprise Linux (RHEL) 9 does not easily support these older package versions. This is a recurring problem I always face.

I have been using Red Hat Enterprise Linux (RHEL) since I started my career, which is 6.7 years.

I have not experienced stability issues. I have used multiple OEMs including HP, Dell, Exatron, and NVIDIA servers. I always prefer recommending Red Hat Enterprise Linux (RHEL) to my customers because it is very stable. I have only experienced one server crash in all my years, and that was due to an OEM issue, not Red Hat Enterprise Linux (RHEL) itself. I have never encountered data problems or server crashes from Red Hat Enterprise Linux (RHEL).

Scalability is not an issue. I can easily add more nodes to clusters. The installation is very fast, which allows me to scale quickly. I use Ansible  and PXE servers to facilitate this process, and I can scale to many servers very quickly with Red Hat Enterprise Linux (RHEL).

When I was working for a customer and faced an issue while installing a package, I requested Red Hat support and they helped me resolve it.

I have raised requests in the morning around 11:00 AM and received responses within one to two hours. They ask for logs and version information, and then provide a response within approximately 30 minutes. I give Red Hat support a nine out of 10 rating. I would give a full 10 if they could push their support to be slightly faster. When someone is on-site conducting installations and encounters an issue, that person needs to wait at least one or two hours for a response. Red Hat could improve by responding a bit more quickly.

Regarding the pricing of Red Hat Enterprise Linux (RHEL) subscription, I believe the pricing is fair. The support that Red Hat provides is very good. Whenever I encounter issues, Red Hat always provides fast resolution. The pricing is justified given the quality of support offered.

I have used Ubuntu  as an alternative distribution. However, I always choose Red Hat Enterprise Linux (RHEL) over every other distribution. I started my career learning from Red Hat Enterprise Linux (RHEL), which is the main reason I prefer it. Additionally, Ubuntu and other distributions have many dependencies that require adding different packages and configurations. When troubleshooting on Red Hat Enterprise Linux (RHEL), I find solutions easily. With Ubuntu, troubleshooting requires digging much deeper.

I have been working with Red Hat Enterprise Linux (RHEL) for approximately seven years.

Regarding updates and maintenance, I only need maintenance time when upgrading the OS. When upgrading the kernel version or transitioning from RHEL 8 to RHEL 9, I only need to install the RPMs and reboot the server once. Maintenance primarily involves patching and the subsequent reboot requirement.

Every time a cluster issue occurs, Red Hat never requests high downtime or suggests data loss scenarios. They maintain very low risk and require very low downtime.
