We use Red Hat Enterprise Linux servers and Satellite for patch management. We're also using Ansible for automation and hardening. Additionally, I'm doing a migration project from RHEL 7 to RHEL 9. Our environment is a mixture of on-prem and cloud systems. We are a hospital, so we can't keep some information on the cloud for compliance reasons. 

We have a separate team for the hybrid, and I'm part of that team. We've been migrating a few servers from on-prem to the cloud. Everything used to be on a hardware server, but now we use the cloud for the storage network. We share workloads between the cloud and the physical data center. Our Rubrik data backup archives to the cloud with Microsoft Azure. We also partner with Pure Storage, which we use for on-prem storage.

We have physical Red Hat Enterprise Linux servers for the Splunk environment, which is the security solution we use. Hadoop went to the cloud, but it used to be on Red Hat Enterprise Linux. We have VMware, and our VMs are reserved for Red Hat Enterprise Linux.

We have been using Red Hat since I was hired. All the app owners want Red Hat. Red Hat Enterprise Linux supports SQL and Oracle databases, which is helpful.

Red Hat Enterprise Linux has made significant improvements in terms of storage. You can mount an 18 terabyte file system. It also supports NFS shares and the SIP share for the photos. There have been many features added since RHEL 6. It's more user-friendly and graphical. 

We use Ansible as a go-to for provisioning and hardening the servers. It's so much easier with Ansible because we used scripts in the past. We had to log into each server as such, and it took a long time. With Ansible, we just run one playbook, and it takes care of everything. 

I used Leapp for my upgrade from RHEL 7 to 8. It's an excellent utility tool. When I run the Leapp script, it tells me everything I need to take care of before I run a migration. Red Hat Insight is good because it tells you about the future patches available. 

We use Red Hat Enterprise Linux image builder. Our golden image is a real image. We harden it, and it's our golden server. When we need a new VM, we can just make a snapshot of that. If it's a physical server, then I have to do it manually.

AIX will be out of support in the next few years, so that is a problem because a lot of the clinical apps use AIX. 

I have used Red Hat Enterprise Linux since I started working at this hospital six years ago.  

I rate Red Hat support eight out of 10. It's helpful when we face hardware issues, kernel panics, or the server is hanging. We always open a support case with Red Hat, and they're helpful at every level. It used to be in the United States, but now they outsource everything to India, so there is a big time difference. That's the only issue. 

Positive

We have always used Red Hat, but they use CentOS for a few applications. Most are using Red Hat. Another team uses Microsoft Windows 2016. It's a different team. The application team decides which one they prefer, but most clinicians use Red Hat Enterprise Linux servers.

The application owners like Red Hat instead of CentOS or another flavor of Linux because the support is reliable. If something breaks, they can call Red Hat support. It's the enterprise standard Linux.

I do the Red Hat Enterprise Linux upgrades. It's straightforward because I can just run Leapp to upgrade it

I rate Red Hat Enterprise Linux nine out of 10. 

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.

The SAP solution subscriptions have made things a lot easier because it's a standard build. 

The solutions were premium and standard, which were not the same. They've combined those into just one standard version. Only the support hours are different. That is fantastic for us. It makes life easier.

For the standard subscriptions, in the past, updating the OS could increase your downtime. With the production ones, it did not. It got our non-production and production out of sync. Now, they've combined that all into one. It's just the support hours that are different. They're fantastic.

We use the SAP solution subscriptions only for SAP, which are great. 

We also use Ansible. Ansible is a wonderful tool for automation. We use it to automate our patching. We use Ansible to get playbooks to take care of anything that's manual.

We were able to achieve our security standard certifications.

Red Hat Enterprise Linux has affected our HA systems in a negative way. We're working through some of those issues.

Red Hat Enterprise Linux 8 came up with a new feature that's like a MOM API in our cluster. It goes out into the AWS side and it needs to be adjusted. It does a retry that causes a cluster to failover pretty quickly, so we turned that feature off. That's something that could be improved. 

I have been using Red Hat Enterprise Linux for a long time. It has been at least 10 to 15 years.

Support has been great. We get the right people for what we need.

Positive

The patching has been good, but we scan with Qualys all the time. It comes up with thousands of EIDs all the time, but putting on the patches seems to resolve that.

We're operating right now from 7.9 to 8.6. We have to go with the supported versions. We did qualify for RHEL 9. 

We used Unix in the past. We did have to come up with the SAP side. It was always Unix.

Overall, I would rate the solution an eight out of ten. 

We are currently in the midst of a POC phase with a standalone cluster. This cluster consists of both coordinator and worker nodes, with a metadata store for storing various metadata. The entire setup is deployed on Red Hat Enterprise Linux 8, and we have established a connection to the OpenShift UI.

While using it, we encountered far fewer complexities, and the entire process is much smoother and streamlined. For patching purposes, we simply need to communicate with our system administrator. They take care of the patching process, so we don't have to get involved and we can easily connect to the artifact repository and download the necessary artifacts to install in our system. 

We have a set of JSON files containing YAML configurations where all the required image details are documented and this setup makes it very straightforward for us.As for the Web Console, if you're talking about the user interface for tasks like creating ports, deploying applications, managing secrets, and other functions, I haven't encountered any significant issues. 

The process is generally straightforward and quick, taking just a few minutes. OpenShift offers two types of interfaces: one where you can edit YAML files for more advanced customization, and the other where you can use forms for faster deployment, though with fewer features.

Continuous improvement is essential to enhance user experiences and address evolving needs.

I have been working with it for approximately six months.

Our experience with its customer support is very good. Whenever we encounter any issues, we receive prompt and comprehensive assistance. There's no need to wait or take any additional steps to get the help we require, which is highly appreciated. I would rate it nine out of ten.

Positive

In the past, our work primarily involved Hadoop, and we also dealt with Solid Cloud for security and other purposes, but we found that this setup was slow and not open source. On the other hand, the DLP solution we're currently using is not only cost-effective but also significantly faster. 

I also used a Linux browser, specifically the KCL browser which required me to go through the process of installing packages and various components, while in the current setup, everything is seamlessly connected. We simply use the OC command with a private key to connect to OpenShift. There are no extra or additional steps required, making the whole process exceptionally fast and efficient. It's quite remarkable and makes the workflow truly hassle-free.

The initial setup was easy.

The deployment process is straightforward. I simply had to deploy the images using OC commands, and the process of connecting to OpenShift was remarkably fast and smooth.

Overall, I would rate it nine out of ten.

Our use case for Red Hat Enterprise Linux is for production applications. 

We are a Managed Service Provider. Red Hat Enterprise Linux enables us not to be worried about vulnerabilities, security, and patching.

The most valuable features are the subscriptions and upgrades. 

We need to have more flexibility on the developed versions. Not everybody is ready to subscribe to enterprise versions. They would like to test the tool without subscriptions. 

We chose Red Hat Enterprise Linux because of its security. 

We use Red Hat Enterprise Linux with AWS. We started our practice with AWS, and most customers use it instead of GCP or Azure. We use the product in a hybrid environment, mostly when shifting the containers or existing workloads from legacy systems. 

Most of the customers use Red Hat Enterprise Linux because it is the only approved OS. The tool's knowledge base is good but is limited to subscriptions. 

The upgrade migration is straightforward. For the initial projects, we used to execute CLI scripts. We plan to upgrade the system if everything works well in the lower environment. 

I have used the image builder feature. I rate the overall product a nine out of ten. 

We use Red Hat Enterprise Linux for VMs and physical servers. 

The containerized platform will help us use ROSA. 

The tool's most valuable feature is OpenShift. We plan to move all our applications to microservices. The container platform is integrated into one.

I opened a few cases, and the tool's support responded quickly. 

Positive

Deployment is simple if you have been using the solution for a long time. However, it can be complex if you are new to it. 

We use RHEL 7 and RHEL 8 on on-premises. RHEL 8 is on the AWS. There is a security policy like CIS when deploying the solution. You can embed it on the image. I am not sure if there is HIPAA compliance yet. 

Migration from RHEL 8 to RHEL 9 is easy. Upgrade depends on the application that is running on each instance. You need to check if it is compatible with the kernel. We need to plan things before migrating to the latest version. We need to stay current to ensure compliance. We plan to move from RHEL 7 to RHEL 9 and use RHEL 8 and RHEL 9. 

We use Red Hat insights but do not utilize them. It helps with the remediation. I use Image Builder to build AWS and GCP images. I haven't deployed them. 

I rate the product a nine out of ten. 

We have over a thousand VMs or physical machines running on Red Hat Enterprise Linux. We have various applications, and we also run the OpenShift Container Platform on-prem, so we have a lot of containers. They are migrating a lot of apps from the mainframe over to Spring Boot type of app. It fits well in the container.

Red Hat Enterprise Linux gave us stability. There is somebody to call when we have issues.

Red Hat Enterprise Linux has affected our system's uptime or security.

Red Hat Enterprise Linux has not yet enabled us to achieve security standards certification because we do not go after any of those. There are some products that we will have to do once we get there, but so far, we have not had to certify anything.

Red Hat Insights gives a lot of insights into known issues that we do not think about unless we call support. It tells us to proactively fix something.

I have used Image Builder and System Roles mainly for Red Hat Enterprise Linux for Edge. It builds out the OS tree build for us, which is very helpful. I do not like to do that myself.

I use the Red Hat console every now and then, but I do not use it heavily. I am old school.

The security updates and the support that comes along with it for applications are valuable.

Red Hat Insights was a nice feature to discover. I did not know about Ansible until probably eight years ago. I learned that language, and that was a void or something that was missing for over 25 years.

I like the SCAP Workbench interface that I can use to build some security around. I use Ansible to go out and do configuration management checks as well. Overall, I feel it is very easy to get the data I need.

We finally started doing Red Hat Enterprise Linux for Edge. That one definitely is an improvement. One piece that is missing is that we are required to use moby-engine, but currently, Red Hat Enterprise Linux for Edge forces Podman, so we have to work around it.

I have been using Red Hat Enterprise Linux for a decade in my current organization, but overall, I have been using Red Hat for over 25 years.

Early on, support was closer to a six, but now, it is a nine out of ten.

Positive

I have used them all back from the early nineties. I have used CentOS and others. The reasons for companies switching from those to Red Hat Enterprise Linux are that most of it is open source, and they get more product features. There is a market. If other companies are doing it, they tend to switch over. Containerization is a major reason as well.

I was involved in the OpenShift deployments. We are also directly involved in every version of Red Hat Enterprise Linux. We are involved in the proof of concept. Its deployment is straightforward.

We used Red Hat with the OpenShift deployments to make sure we were doing it right, and then a lot of other things, such as Red Hat Enterprise Linux 8 or Red Hat Enterprise Linux 9, we just did ourselves.

In terms of our upgrade and/or migration plans to stay current, we are upgrading everything to Red Hat Enterprise Linux 8, and we are going to Red Hat Enterprise Linux 9 already. We are making that a product feature. We are using Red Hat Enterprise Linux for Edge for our remote deployments.

In terms of provisioning and patching, we deploy the base image, and then we use Ansible for the configuration behind it. For Red Hat Enterprise Linux for Edge, we use the OS builders to build out that same image. I use Kickstart to build the base image before the configuration.

I do not track that in the company, but I am sure we have seen an ROI.

It seems to be fair. It is not overpriced. I went to the simple model, and that makes it easier for us to deploy.

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

We use Red Hat Enterprise Linux for off-the-shelf applications and Oracle databases. 

The tool is simple and easy to use. It has good support and doesn't have many outages due to the OS. 

The cockpit server doesn't work and is useless. I don't like the images shown in GCP. I prefer the ones in AWS. It seems like the solution is in tune with what we deploy on the private cloud. 

I have been using the solution for ten years. 

We open a case whenever we need support. Whenever I need support, I contact the technical guy assigned to us and provide him with the documentation. 

Positive

I have used different OS like Motorola, Unix Flavors, Solaris, HP-UX, AIX, DG/UX, and Sonos OS. Unix is dying, and everything is moving to Linux. Linux is open-source and easier to use. 

We build our own deployment method. 

Red Hat Enterprise Linux is expensive. We have changed the cloud provider's subscription to a pay-as-you-go model. 

We use the on-premise, cloud, and hybrid versions. We have deployed it on AWS, Microsoft Azure, and Google Cloud. Most of our infrastructure is in the Azure cloud. I work in the server infrastructure team, and other data collectors work on AWS and GCP. We haven't used the tool's features like the image builder. 

The product supports our hybrid cloud strategy. We have been migrating using tools from Microsoft Azure. Its knowledge base is good. Sometimes, finding an article is difficult. However, once I reach them, it contains good information. 

We used Azure's tools for migration to the cloud. It is straightforward. We have no problems deploying the servers. Our main strategy focused on data centers.

We use the Leapp tool to manage the upgrades. It works smoothly on our Oracle databases. Leapp is straightforward to use. 

We use Red Hat Insights quite a bit. I have not explored all the features yet. We use it to look for events our monitoring hasn't picked up. It also helps us with tips and hints for fine-tuning applications like SAP and Oracle. We go by these recommendations and follow them to put the applications in place. I have downloaded the Playbooks for remediation. 

I use system rules for SAP tuning in Oracle. I do not use the image builder since we already have a process to do the server builds. I use the web console once in a while. 

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

For the past couple of years, our contractor team has been engaged with the Department of Veterans Affairs, focusing on developing and deploying software and containers and we use Red Hat Enterprise Linux for that.

One of the most valuable aspects is the ease of installing packages on the server. When we need to run specific software, adding and installing packages on Red Hat Enterprise Linux is quite straightforward.

When we initially began working with containers, we encountered some challenges with compatibility. Red Hat provided an older and somewhat outdated version of Docker, which made the early stages of our container journey more challenging than I would have preferred.

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

The customer support they provide is highly commendable. I would rate it nine out of ten.

Positive

I've mainly used Windows on my computer or laptop. However, it was a different scenario when we were developing in the cloud and were given Red Hat Enterprise Linux servers to work with.

We regularly perform upgrades on our OpenShift clusters, typically on a monthly basis. When it comes to the Red Hat Enterprise Linux servers, we frequently update the images on our virtual machines to ensure that we stay current with the latest versions. We're actively working on implementing automation using Ansible to streamline and facilitate these tasks.

Overall, I would rate it nine out of ten.
